Tanafed DMX Suspension


Pronunciation: dex-klor-fen-EER-a-meen/dex-troe-meth-OR-fan/sue-doe-eh-FED-rin
Generic Name: Dexchlorpheniramine/Dextromethorphan/Pseudoephedrine
Brand Name: Examples include TanaCof DM and Tanafed DMX


Tanafed DMX Suspension is used for:

Relieving symptoms of sinus congestion, runny nose, sneezing, cough due to colds, upper respiratory infections, and allergies. It may also be used for other conditions as determined by your doctor.


Tanafed DMX Suspension is a decongestant, antihistamine, and cough suppressant combination. It works by constricting blood vessels and reducing swelling in the nasal passages. The antihistamine works by blocking the action of histamine, which helps reduce symptoms, such as watery eyes and sneezing, while the cough suppressant works in the brain to help decrease the cough reflex to reduce a dry cough.


Do NOT use Tanafed DMX Suspension if:


  • you are allergic to any ingredient in Tanafed DMX Suspension

  • you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, or severe heart problems

  • you are unable to urinate or are having an asthma attack

  • you take sodium oxybate (GHB) or you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (eg, phenelzine) within the last 14 days

Contact your doctor or health care provider right away if any of these apply to you.

Xodol



hydrocodone bitartrate and acetaminophen

Dosage Form: tablet

Warning




HEPATOTOXICITY


ACETAMINOPHEN HAS BEEN ASSOCIATED WITH CASES OF ACUTE LIVER FAILURE, AT TIMES RESULTING IN LIVER TRANSPLANT AND DEATH. MOST OF THE CASES OF LIVER INJURY ARE ASSOCIATED WITH THE USE OF ACETAMINOPHEN AT DOSES THAT EXCEED 4000 MILLIGRAMS PER DAY, AND OFTEN INVOLVE MORE THAN ONE ACETAMINOPHEN-CONTAINING PRODUCT.



Xodol Description

Hydrocodone bitartrate and acetaminophen is supplied in tablet form for oral administration.


WARNING: May be habit-forming (see PRECAUTIONS, Information for Patients/Caregivers, and DRUG ABUSE AND DEPENDENCE).

This product complies with USP dissolution test 2.



Xodol - Clinical Pharmacology


Hydrocodone is a semisynthetic narcotic analgesic and antitussive with multiple actions qualitatively similar to those of codeine. Most of these involve the central nervous system and smooth muscle. The precise mechanism of action of hydrocodone and other opiates is not known, although it is believed to relate to the existence of opiate receptors in the central nervous system. In addition to analgesia, narcotics may produce drowsiness, changes in mood and mental clouding.


The analgesic action of acetaminophen involves peripheral influences, but the specific mechanism is as yet undetermined. Antipyretic activity is mediated through hypothalamic heat regulating centers. Acetaminophen inhibits prostaglandin synthetase. Therapeutic doses of acetaminophen have negligible effects on the cardiovascular or respiratory systems; however, toxic doses may cause circulatory failure and rapid, shallow breathing.



Pharmacokinetics


The behavior of the individual components is described below.


Hydrocodone: Following a 10 mg oral dose of hydrocodone administered to five adult male subjects, the mean peak concentration was 23.6 ± 5.2 ng/mL. Maximum serum levels were achieved at 1.3 ± 0.3 hours and the half-life was determined to be 3.8 ± 0.3 hours. Hydrocodone exhibits a complex pattern of metabolism including O-demethylation, N-demethylation and 6-keto reduction to the corresponding 6-α- and 6-β-hydroxymetabolites. See OVERDOSAGE for toxicity information.


Acetaminophen: Acetaminophen is rapidly absorbed from the gastrointestinal tract and is distributed throughout most body tissues. The plasma half-life is 1.25 to 3 hours, but may be increased by liver damage and following overdosage. Elimination of acetaminophen is principally by liver metabolism (conjugation) and subsequent renal excretion of metabolites. Approximately 85% of an oral dose appears in the urine within 24 hours of administration, most as the glucuronide conjugate, with small amounts of other conjugates and unchanged drug. See OVERDOSAGE for toxicity information.



Indications and Usage for Xodol


Xodol® is indicated for the relief of moderate to moderately severe pain.



Contraindications


This product should not be administered to patients who have previously exhibited hypersensitivity to hydrocodone or acetaminophen.


Patients known to be hypersensitive to other opioids may exhibit cross sensitivity to hydrocodone.



Warnings



Hepatotoxicity


Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing product. The excessive intake of acetaminophen may be intentional to cause self-harm or unintentional as patients attempt to obtain more pain relief or unknowingly take other acetaminophen-containing products.


The risk of acute liver failure is higher in individuals with underlying liver disease and in individuals who ingest alcohol while taking acetaminophen.


Instruct patients to look for acetaminophen or APAP on package labels and not to use more than one product that contains acetaminophen. Instruct patients to seek medical attention immediately upon ingestion of more than 4000 milligrams of acetaminophen per day, even if they feel well.



Hypersensitivity/anaphylaxis


There have been post-marketing reports of hypersensitivity and anaphylaxis associated with use of acetaminophen. Clinical signs included swelling of the face, mouth, and throat, respiratory distress, urticaria, rash, pruritus, and vomiting. There were infrequent reports of life-threatening anaphylaxis requiring emergency medical attention. Instruct patients to discontinue Xodol® immediately and seek medical care if they experience these symptoms. Do not prescribe Xodol® for patients with acetaminophen allergy.



Respiratory Depression


At high doses or in sensitive patients, hydrocodone may produce dose-related respiratory depression by acting directly on the brain stem respiratory center. Hydrocodone also affects the center that controls respiratory rhythm, and may produce irregular and periodic breathing.



Head Injury and Increased Intracranial Pressure


The respiratory depressant effects of narcotics and their capacity to elevate cerebrospinal fluid pressure may be markedly exaggerated in the presence of head injury, other intracranial lesions or a pre-existing increase in intracranial pressure. Furthermore, narcotics produce adverse reactions which may obscure the clinical course of patients with head injuries.



Acute Abdominal Conditions


The administration of narcotics may obscure the diagnosis or clinical course of patients with acute abdominal conditions.



Precautions



General


Special Risk Patients: As with any narcotic analgesic agent, hydrocodone bitartrate and acetaminophen tablets should be used with caution in elderly or debilitated patients, and those with severe impairment of hepatic or renal function, hypothyroidism, Addison’s disease, prostatic hypertrophy or urethral stricture. The usual precautions should be observed and the possibility of respiratory depression should be kept in mind.


Cough Reflex: Hydrocodone suppresses the cough reflex; as with all narcotics, caution should be exercised when hydrocodone bitartrate and acetaminophen tablets are used postoperatively and in patients with pulmonary disease.



Information for Patients/Caregivers


  • Do not take Xodol® if you are allergic to any of its ingredients.

  • If you develop signs of allergy such as a rash or difficulty breathing, stop taking Xodol® and contact your healthcare provider immediately.

  • Do not take more than 4000 milligrams of acetaminophen per day. Call your doctor if you took more than the recommended dose.

Hydrocodone, like all narcotics, may impair mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery; patients should be cautioned accordingly.


Alcohol and other CNS depressants may produce an additive CNS depression, when taken with this combination product, and should be avoided.


Hydrocodone may be habit-forming. Patients should take the drug only for as long as it is prescribed, in the amounts prescribed, and no more frequently than prescribed.



Laboratory Tests


In patients with severe hepatic or renal disease, effects of therapy should be monitored with serial liver and/or renal function tests.



Drug Interactions


Patients receiving other narcotics, antihistamines, antipsychotics, antianxiety agents, or other CNS depressants (including alcohol) concomitantly with hydrocodone bitartrate and acetaminophen tablets may exhibit an additive CNS depression. When combined therapy is contemplated, the dose of one or both agents should be reduced.


The use of MAO inhibitors or tricyclic antidepressants with hydrocodone preparations may increase the effect of either the antidepressant or hydrocodone.



Drug/Laboratory Test Interactions


Acetaminophen may produce false-positive test results for urinary 5-hydroxyindoleacetic acid.



Carcinogenesis, Mutagenesis, Impairment of Fertility


No adequate studies have been conducted in animals to determine whether hydrocodone or acetaminophen have a potential for carcinogenesis, mutagenesis, or impairment of fertility.



Pregnancy


Teratogenic Effects

Pregnancy Category C


There are no adequate and well-controlled studies in pregnant women. Xodol® should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.


Nonteratogenic Effects

Babies born to mothers who have been taking opioids regularly prior to delivery will be physically dependent. The withdrawal signs include irritability and excessive crying, tremors, hyperactive reflexes, increased respiratory rate, increased stools, sneezing, yawning, vomiting and fever. The intensity of the syndrome does not always correlate with the duration of maternal opioid use or dose. There is no consensus on the best method of managing withdrawal.



Labor and Delivery


As with all narcotics, administration of this product to the mother shortly before delivery may result in some degree of respiratory depression in the newborn, especially if higher doses are used.



Nursing Mothers


Acetaminophen is excreted in breast milk in small amounts, but the significance of its effects on nursing infants is not known. It is not known whether hydrocodone is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from hydrocodone and acetaminophen, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.



Pediatric Use


Safety and effectiveness in pediatric patients have not been established.



Geriatric Use


Clinical studies of hydrocodone bitartrate and acetaminophen tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.


Hydrocodone and the major metabolites of acetaminophen are known to be substantially excreted by the kidney. Thus the risk of toxic reactions may be greater in patients with impaired renal function due to the accumulation of the parent compound and/or metabolites in the plasma. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.


Hydrocodone may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of hydrocodone bitartrate and acetaminophen tablets and observed closely.



Adverse Reactions


The most frequently reported adverse reactions include lightheadedness, dizziness, sedation, nausea and vomiting. These effects seem to be more prominent in ambulatory than in non-ambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down.


Other adverse reactions include:


Central Nervous System: Drowsiness, mental clouding, lethargy, impairment of mental and physical performance, anxiety, fear, dysphoria, psychic dependence, mood changes.


Gastrointestinal System: Prolonged administration of hydrocodone bitartrate and acetaminophen tablets may produce constipation.


Genitourinary System: Ureteral spasm, spasm of vesical sphincters and urinary retention have been reported with opiates


Respiratory Depression: Hydrocodone bitartrate may produce dose-related respiratory depression by acting directly on the brain stem respiratory centers (see OVERDOSAGE).


Special Senses: Cases of hearing impairment or permanent loss have been reported predominantly in patients with chronic overdose.


Dermatological: Skin rash, pruritus.


The following adverse drug events may be borne in mind as potential effects of acetaminophen: allergic reactions, rash, thrombocytopenia, agranulocytosis. Potential effects of high dosage are listed in the OVERDOSAGE section.



Drug Abuse and Dependence


Controlled Substance: Xodol® is classified as a Schedule III controlled substance.


Abuse and Dependence: Psychic dependence, physical dependence, and tolerance may develop upon repeated administration of narcotics; therefore, this product should be prescribed and administered with caution. However, psychic dependence is unlikely to develop when hydrocodone bitartrate and acetaminophen tablets are used for a short time for the treatment of pain.


Physical dependence, the condition in which continued administration of the drug is required to prevent the appearance of a withdrawal syndrome, assumes clinically significant proportions only after several weeks of continued narcotic use, although some mild degree of physical dependence may develop after a few days of narcotic therapy. Tolerance, in which increasingly large doses are required in order to produce the same degree of analgesia, is manifested initially by a shortened duration of analgesic effect, and subsequently by decreases in the intensity of analgesia. The rate of development of tolerance varies among patients.



Overdosage


Following an acute overdosage, toxicity may result from hydrocodone or acetaminophen.



Signs and Symptoms


Hydrocodone: Serious overdose with hydrocodone is characterized by respiratory depression (a decrease in respiratory rate and/or tidal volume, Cheyne-Stokes respiration, cyanosis), extreme somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, and sometimes bradycardia and hypotension. In severe overdosage, apnea, circulatory collapse, cardiac arrest and death may occur.


Acetaminophen: In acetaminophen overdosage: dose-dependent, potentially fatal hepatic necrosis is the most serious adverse effect. Renal tubular necrosis, hypoglycemic coma, and coagulation defects may also occur. Early symptoms following a potentially hepatotoxic overdose may include: nausea, vomiting, diaphoresis and general malaise. Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion.



Treatment


A single or multiple drug overdose with hydrocodone and acetaminophen is a potentially lethal polydrug overdose, and consultation with a regional poison control center is recommended. Immediate treatment includes support of cardiorespiratory function and measures to reduce drug absorption.


Oxygen, intravenous fluids, vasopressors, and other supportive measures should be employed as indicated. Assisted or controlled ventilation should also be considered.


For hydrocodone overdose, primary attention should be given to the reestablishment of adequate respiratory exchange through provision of a patent airway and the institution of assisted or controlled ventilation. The narcotic antagonist naloxone hydrochloride is a specific antidote against respiratory depression which may result from overdosage or unusual sensitivity to narcotics, including hydrocodone. Since the duration of action of hydrocodone may exceed that of the antagonist, the patient should be kept under continued surveillance, and repeated doses of the antagonist should be administered as needed to maintain adequate respiration. A narcotic antagonist should not be administered in the absence of clinically significant respiratory or cardiovascular depression.


Gastric decontamination with activated charcoal should be administered just prior to N-acetylcysteine (NAC) to decrease systemic absorption if acetaminophen ingestion is known or suspected to have occurred within a few hours of presentation. Serum acetaminophen levels should be obtained immediately if the patient presents 4 hours or more after ingestion to assess potential risk of hepatotoxicity; acetaminophen levels drawn less than 4 hours post-ingestion may be misleading. To obtain the best possible outcome, NAC should be administered as soon as possible where impending or evolving liver injury is suspected. Intravenous NAC may be administered when circumstances preclude oral administration.


Vigorous supportive therapy is required in severe intoxication. Procedures to limit the continuing absorption of the drug must be readily performed since the hepatic injury is dose dependent and occurs early in the course of intoxication.



Xodol Dosage and Administration


Dosage should be adjusted according to the severity of the pain and the response of the patient. However, it should be kept in mind that tolerance to hydrocodone can develop with continued use and that the incidence of untoward effects is dose related.


Xodol® 5/300 (Hydrocodone Bitartrate and Acetaminophen Tablets, USP 5 mg/300 mg): The usual adult dosage is one or two tablets every four to six hours as needed for pain. The total daily dosage should not exceed 8 tablets.


Xodol® 7.5/300 (Hydrocodone Bitartrate and Acetaminophen Tablets, USP 7.5 mg/300 mg): The usual adult dosage is one tablet every four to six hours as needed for pain. The total daily dosage should not exceed 6 tablets.


Xodol® 10/300 (Hydrocodone Bitartrate and Acetaminophen Tablets, USP 10 mg/300 mg): The usual adult dosage is one tablet every four to six hours as needed for pain. The total daily dosage should not exceed 6 tablets.

In women transferring from sequential HRT regimens, treatment should start right after their withdrawal bleeding has ended.



If the patient has forgotten to take a tablet, the tablet should be taken as soon as possible within the next twelve hours. If more than 12 hours has passed the tablet should be discarded. Forgetting a dose may increase the likelihood of breakthrough bleeding and spotting.



4.3 Contraindications

Known, past or suspected oestrogen-dependent malignant tumours (e.g. endometrial cancer)



Undiagnosed genital bleeding



Untreated endometrial hyperplasia



Previous idiopathic or current venous thromboembolism (deep venous thrombosis, pulmonary embolism)



Active or recent arterial thromboembolic disease (e.g. angina, myocardial infarction)



Acute liver disease or a history of liver disease as long as liver function tests have failed to return to normal



Known hypersensitivity to the active substances or to any of the excipients

4.4 Special Warnings And Precautions For Use



For the treatment of postmenopausal symptoms, HRT should only be initiated for symptoms that adversely affect quality of life. In all cases, a careful appraisal of the risks and benefits should be undertaken at least annually and HRT should only be continued as long as the benefit outweighs the risk.



Medical examination/follow-up



Before initiating or reinstituting HRT, a complete personal and family medical history should be taken. Physical (including pelvic and breast) examination should be guided by this and by the contraindications and warnings for use. During treatment periodic check-ups are recommended of a frequency and nature adapted to the individual woman. Women should be advised what changes in their breasts should be reported to their doctor or nurse (please see "Breast cancer" section below). Investigations, including mammography, should be carried out in accordance with currently accepted screening practices, modified to the clinical needs of the individual.



Conditions which need supervision



If any of the following conditions are present, have occurred previously and/or have been aggravated during pregnancy or previous hormone treatment, the patient should be closely supervised. It should be taken into account that these conditions may recur or be aggravated during treatment with Kliovance, in particular:



Leiomyoma (uterine fibroids) or endometriosis



A history of, or risk factors for, thromboembolic disorders (see below)



Risk factors for oestrogen dependent tumours, e.g. 1st degree heredity for breast cancer



Hypertension



Liver disorders (e.g. liver adenoma)



Diabetes mellitus with or without vascular involvement



Cholelithiasis



Migraine or (severe) headache



Systemic lupus erythematosus



A history of endometrial hyperplasia (see below)



Epilepsy



Asthma



Otosclerosis



Reasons for immediate withdrawal of therapy



Therapy should be discontinued in case a contra-indication is discovered and in the following situations:



- Jaundice or deterioration in liver function



- Significant increase in blood pressure



- New onset of migraine-type headache



- Pregnancy



Endometrial hyperplasia



The risk of endometrial hyperplasia and carcinoma is increased when oestrogens are administered alone for prolonged periods (see section 4.8). The addition of a progestagen for at least 12 days per cycle in non-hysterectomised women greatly reduces this risk.



Breakthrough bleeding and spotting may occur during the first months of treatment. If breakthrough bleeding or spotting appears after some time on therapy, or continues after treatment has been discontinued, the reason should be investigated, which may include endometrial biopsy to exclude endometrial malignancy.



Breast cancer



A randomised placebo-controlled trial, the Women's Health Initiative study (WHI), and epidemiological studies, including the Million Women Study (MWS), have reported an increased risk of breast cancer in women taking oestrogens, oestrogen-progestagen combinations or tibolone for HRT for several years (see Section 4.8).



For all HRT, an excess risk becomes apparent within a few years of use and increases with duration of intake but returns to baseline within a few (at most five) years after stopping treatment.



In the MWS, the relative risk of breast cancer with conjugated equine oestrogens (CEE) or estradiol (E2) was greater when a progestagen was added, either sequentially or continuously, and regardless of type of progestagen. There was no evidence of a difference in risk between the different routes of administration.



In the WHI study, the continuous combined conjugated equine oestrogen and medroxyprogesterone acetate (CEE + MPA) product used was associated with breast cancers that were slightly larger in size and more frequently had local lymph node metastases compared to placebo.



HRT, especially oestrogen-progestagen combined treatment, increases the density of mammographic images which may adversely affect the radiological detection of breast cancer.



Venous thromboembolism



HRT is associated with a higher relative risk of developing venous thromboembolism (VTE), i.e. deep vein thrombosis or pulmonary embolism. One randomised controlled trial and epidemiological studies found a two- to threefold higher risk for users compared with non-users. For non-users it is estimated that the number of cases of VTE that will occur over a 5 year period is about 3 per 1000 women aged 50-59 years and 8 per 1000 women aged between 60-69 years. It is estimated that in healthy women who use HRT for 5 years, the number of additional cases of VTE over a 5 year period will be between 2 and 6 (best estimate=4) per 1000 women aged 50-59 years and between 5 and 15 (best estimate=9) per 1000 women aged 60-69 years. The occurrence of such an event is more likely in the first year of HRT than later.



Generally recognised risk factors for VTE include a personal history or family history, severe obesity (Body Mass Index> 30 kg/m2) and systemic lupus erythematosus (SLE). There is no consensus about the possible role of varicose veins in VTE.



Patients with a history of VTE or known thrombophilic states have an increased risk of VTE. HRT may add to this risk. Personal or strong family history of thromboembolism, or recurrent spontaneous abortion, should be investigated in order to exclude a thrombophilic predisposition. Until a thorough evaluation of thrombophilic factors has been made or anticoagulant treatment initiated, use of HRT in such patients should be viewed as contraindicated. Those women already on anticoagulant treatment require careful consideration of the benefit-risk of use of HRT.



The risk of VTE may be temporarily increased with prolonged immobilisation, major trauma or major surgery. As in all postoperative patients, scrupulous attention should be given to prophylactic measures to prevent VTE following surgery. Where prolonged immobilisation is liable to follow elective surgery, particularly abdominal or orthopaedic surgery to the lower limbs, consideration should be given to temporarily stopping HRT four to six weeks earlier, if possible. Treatment should not be restarted until the woman is completely mobilised.



If VTE develops after initiating therapy, the drug should be discontinued. Patients should be told to contact their doctors immediately when they are aware of a potential thromboembolic symptom (e.g. painful swelling of a leg, sudden pain in the chest, dyspnea).



Coronary artery disease (CAD)



There is no evidence from randomised controlled trials of cardiovascular benefit with continuous combined conjugated oestrogens and medroxyprogesterone acetate (MPA). Two large clinical trials (WHI and HERS i.e. Heart and Estrogen/progestin Replacement Study) showed a possible increased risk of cardiovascular morbidity in the first year of use and no overall benefit. For other HRT products there are only limited data from randomised controlled trials examining effects in cardiovascular morbidity or mortality. Therefore, it is uncertain whether these findings also extend to other HRT products.



Stroke



One large randomised clinical trial (WHI-trial) found, as a secondary outcome, an increased risk of ischaemic stroke in healthy women during treatment with continuous combined conjugated oestrogens and MPA. For women who do not use HRT, it is estimated that the number of cases of stroke that will occur over a 5 year period is about 3 per 1000 women aged 50-59 years and 11 per 1000 women aged 60-69 years. It is estimated that for women who use conjugated oestrogens and MPA for 5 years, the number of additional cases will be between 0 and 3 (best estimate=1) per 1000 users aged 50-59 years and between 1 and 9 (best estimate=4) per 1000 users aged 60-69 years. It is unknown whether the increased risk also extends to other HRT products.



Ovarian cancer



Long-term (at least 5 or 10 years) use of oestrogen-only HRTs and oestrogen plus progestogen HRTs has been associated with an increased risk of ovarian cancer in some epidemiological studies.



Other conditions



Oestrogens may cause fluid retention, and therefore patients with cardiac or renal dysfunction should be carefully observed. Patients with terminal renal insufficiency should be closely observed, since it is expected that the level of circulating active ingredients in Kliovance will increase.



Women with pre-existing hypertriglyceridemia should be followed closely during oestrogen replacement or hormone replacement therapy, since rare cases of large increases of plasma triglycerides leading to pancreatitis have been reported with oestrogen therapy in this condition.



Oestrogens increase thyroid binding globulin (TBG), leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 levels (by column or by radio-immunoassay) or T3 levels (by radio-immunoassay). T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Other binding proteins may be elevated in serum, i.e. corticoid binding globulin (CBG), sex-hormone-binding globulin (SHBG) leading to increased circulating corticosteroids and sex steroids, respectively. Free or biological active hormone concentrations are unchanged. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-I-antitrypsin, ceruloplasmin).



There is no conclusive evidence for improvement of cognitive function. There is some evidence from the WHI trial of increased risk of probable dementia in women who start using continuous combined CEE and MPA after the age of 65. It is unknown whether the findings apply to younger post-menopausal women or other HRT products.



Kliovance tablets contain lactose monohydrate. Patients with rare heredity problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



The metabolism of oestrogens and progestagens may be increased by concomitant use of substances known to induce drug-metabolising enzymes, specifically cytochrome P450 enzymes such as anticonvulsants (e.g. phenobarbital, phenytoin, carbamazepin) and anti-infectives (e.g. rifampicin, rifabutin, nevirapine, efavirenz).



Ritonavir and nelfinavir, although known as strong inhibitors, by contrast exhibit inducing properties when used concomitantly with steroid hormones. Herbal preparations containing St John's Wort (Hypericum perforatum) may induce the metabolism of oestrogens and progestagens.



Clinically, an increased metabolism of oestrogens and progestagens may lead to decreased effect and changes in the uterine bleeding profile.



Drugs that inhibit the activity of hepatic microsomal drug metabolizing enzymes e.g. ketoconazole, may increase circulating levels of the active substances in Kliovance.



4.6 Pregnancy And Lactation



Kliovance is not indicated during pregnancy.



If pregnancy occurs during medication with Kliovance, treatment should be withdrawn immediately.



Data on a limited number of exposed pregnancies indicate adverse effects of norethisterone on the foetus. At doses higher than normally used in OC and HRT formulations masculinisation of female foetuses was observed. The results of most epidemiological studies to date relevant to inadvertent foetal exposure to combinations of oestrogens and progestagens indicate no teratogenic or foetotoxic effect.



Lactation



Kliovance is not indicated during lactation.



4.7 Effects On Ability To Drive And Use Machines



No effects known.



4.8 Undesirable Effects



Clinical experience:



The most frequently reported adverse events in the clinical trials with Kliovance were vaginal bleeding and breast pain/tenderness, reported in approximately 10% to 20% of patients. Vaginal bleeding usually occurred in the first months of treatment. Breast pain usually disappeared after a few months of therapy. All adverse events observed in the randomised clinical trials with a higher frequency in patients treated with Kliovance as compared to placebo and which on an overall judgement are possibly related to treatment are presented in the table below.

Breast cancer



According to evidence from a large number of epidemiological studies and one randomised placebo-controlled trial, the Women's Health Initiative (WHI), the overall risk of breast cancer increases with increasing duration of HRT use in current or recent HRT users.



For oestrogen-only HRT, estimates of relative risk (RR) from a reanalysis of original data from 51 epidemiological studies (in which>80% of HRT use was oestrogen-only HRT) and from the epidemiological Million Women Study (MWS) are similar at 1.35 (95%CI 1.21 – 1.49) and 1.30 (95%CI 1.21 – 1.40), respectively.



For oestrogen plus progestagen combined HRT, several epidemiological studies have reported an overall higher risk for breast cancer than with oestrogens alone.



The MWS reported that, compared to never users, the use of various types of oestrogen-progestagen combined HRT was associated with a higher risk of breast cancer (RR = 2.00, 95%CI: 1.88 – 2.12) than use of oestrogens alone (RR = 1.30, 95%CI: 1.21 – 1.40) or use of tibolone (RR=1.45; 95%CI 1.25-1.68).



The WHI trial reported a risk estimate of 1.24 (95%CI 1.01 – 1.54) after 5.6 years of use of oestrogen-progestagen combined HRT (CEE + MPA) in all users compared with placebo.



The absolute risks calculated from the MWS and the WHI trial are presented below:



The MWS has estimated, from the known average incidence of breast cancer in developed countries, that:



• For women not using HRT, about 32 in every 1000 are expected to have breast cancer diagnosed between the ages of 50 and 64 years.



• For 1000 current or recent users of HRT, the number of additional cases during the corresponding period will be






 




• For users of oestrogen-only replacement therapy








 




• between 0 and 3 (best estimate = 1.5) for 5 years' use




 




• between 3 and 7 (best estimate = 5) for 10 years' use.






 




• For users of oestrogen plus progestagen combined HRT,








 




• between 5 and 7 (best estimate = 6) for 5 years' use




 




• between 18 and 20 (best estimate = 19) for 10 years' use.



The WHI trial estimated that after 5.6 years of follow-up of women between the ages of 50 and 79 years, an additional 8 cases of invasive breast cancer would be due to oestrogen-progestagen combined HRT (CEE + MPA) per 10,000 women years.



According to calculations from the trial data, it is estimated that:



• For 1000 women in the placebo group,






 




• about 16 cases of invasive breast cancer would be diagnosed in 5 years.



• For 1000 women who used oestrogen + progestagen combined HRT (CEE + MPA), the number of additional cases would be






 




• between 0 and 9 (best estimate = 4) for 5 years' use.



The number of additional cases of breast cancer in women who use HRT is broadly similar for women who start HRT irrespective of age at start of use (between the ages of 45-65) (see section 4.4).



Endometrial cancer



In women with an intact uterus, the risk of endometrial hyperplasia and endometrial cancer increases with increasing duration of use of unopposed oestrogens. According to data from epidemiological studies, the best estimate of the risk is that for women not using HRT, about 5 in every 1000 are expected to have endometrial cancer diagnosed between the ages of 50 and 65. Depending on the duration of treatment and oestrogen dose, the reported increase in endometrial cancer risk among unopposed oestrogen users varies from 2-to 12-fold greater compared with non-users. Adding a progestagen to oestrogen-only therapy greatly reduces this increased risk.



Ovarian cancer



Long-term use of oestrogen-only and combined oestrogen-progestogen HRT may slightly increase the risk of ovarian cancer, as reported in some epidemiological studies (see Section 4.4)



Post marketing experience:



In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported, and are by an overall judgement considered possibly related to Kliovance treatment. The reporting rate of these spontaneous adverse drug reactions is very rare (<1/10,000 patient years). Post-marketing experience is subject to underreporting especially with regard to trivial and well known adverse drug reactions. The presented frequencies should be interpreted in that light:



Neoplasms benign and malignant (incl. cysts and polyps): Endometrial cancer



Immune system disorder: Hypersensitivity



Psychiatric disorders: Insomnia, anxiety, libido decreased, libido increased



Nervous system disorders: Dizziness



Eye disorders: Visual disturbances



Vascular disorders: Hypertension aggravated



Gastrointestinal disorders: Dyspepsia, vomiting



Hepatobilitary disorders: Gallbladder disease, cholelithiasis, cholelithiasis aggravated, cholelithiasis re-occurrence



Skin and subcutaneous tissue disorder: Seborrhoea, rash, angioneurotic oedema



Reproductive system and breast disorders: Hyperplasia endometrial, vulvovaginal pruritus



Investigations: Weight decreased, blood pressure increased



Other adverse reactions have been reported in association with oestrogen/progestagen treatment:



- Oestrogen-dependent neoplasms benign and malignant, e.g. endometrial cancer



- Venous thromboembolism, i.e. deep leg or pelvic venous thrombosis and pulmonary embolism, is more frequent among hormone replacement therapy users than among non-users. For further information, see section 4.3 Contraindications and 4.4 Special warnings and precautions for use.



- Myocardial infarction and stroke



- Skin and subcutaneous disorders: chloasma, erythema multiforme, erythema nodosum, vascular purpura.



- Probable dementia (see section 4.4)



4.9 Overdose



Overdose may be manifested by nausea and vomiting. Treatment should be symptomatic.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: progestogens and estrogens, fixed combination, ATC code: G03FA01



Estradiol: The active ingredient, synthetic 17 beta-estradiol, is chemically and biologically identical to endogenous human estradiol. It substitutes for the loss of oestrogen production in menopausal women, and alleviates menopausal symptoms.



Oestrogens prevent bone loss following menopause or ovariectomy.



Norethisterone acetate: As oestrogens promote the growth of the endometrium, unopposed oestrogens increase the risk of endometrial hyperplasia and cancer. The addition of a progestagen greatly reduces the oestrogen-induced risk of endometrial hyperplasia in non-hysterectomised women.



In clinical trials with Kliovance, the addition of the norethisterone acetate component enhanced the vasomotor symptom relieving effect of 17 beta-estradiol.



Relief of menopausal symptoms is achieved during the first few weeks of treatment.



Kliovance is a continuous combined HRT given with the intent of avoiding the regular withdrawal bleeding associated with cyclic or sequential HRT. Amenorrhoea (no bleeding or spotting) was seen in 90% of the women during months 9-12 of treatment. Bleeding and/or spotting appeared in 27% of the women during the first three months of treatment and in 10% during months 10-12 of treatment.



Oestrogen deficiency at menopause is associated with an increasing bone turnover and decline in bone mass. The effect of oestrogens on the bone mineral density is dose-dependent. Protection appears to be effective for as long as treatment is continued. After discontinuation of HRT, bone mass is lost at a rate similar to that in untreated women.



Evidence from the WHI trial and meta-analysed trials shows that current use of HRT, alone or in combination with a progestagen – given to predominantly healthy women – reduces the risk of hip, vertebral, and other osteoporotic fractures. HRT may also prevent fractures in women with low bone density and/or established osteoporosis, but the evidence for that is limited.



The effects of Kliovance on bone mineral density were examined in two 2-year, randomised, double-blind, placebo-controlled clinical trials in postmenopausal women (n=327 in one trial, including 47 on Kliovance and 48 on Kliofem (2 mg estradiol and 1 mg norethisterone acetate); and n=135 in the other trial, including 46 on Kliovance). All women received calcium supplementation ranging from 500 to 1000 mg daily. Kliovance significantly prevented bone loss at the lumbar spine, total hip, distal radius and total body in comparison with calcium supplemented placebo-treated women. In early postmenopausal women (1 to 5 years since last menses), the percentage change from baseline in bone mineral density at lumbar spine, femoral neck and femoral trochanter in patients completing 2 years of treatment with Kliovance was 4.8+0.6%, 1.6+0.7% and 4.3+0.7% (mean + SEM), respectively, while with the higher dose combination containing 2 mg E2 and 1 mg NETA (Kliofem) it was 5.4+0.7%, 2.9+0.8% and 5.0+0.9%, respectively. The percentage of women who maintained or gained bone mineral density during treatment with Kliovance and Kliofem was 87% and 91%, respectively, after 2 years of treatment. In a study conducted in postmenopausal women with a mean age of 58 years, treatment with Kliovance for 2 years increased the bone mineral density at lumbar spine by 5.9+0.9%, at total hip by 4.2+1.0%, at distal radius by 2.1±0.6%, and at total body by 3.7+0.6%.



5.2 Pharmacokinetic Properties



Following oral administration of 17 beta-estradiol in micronized form, rapid absorption from the gastrointestinal tract occurs. It undergoes extensive first-pass metabolism in the liver and other enteric organs, and reaches a peak plasma concentration of approximately 35 pg/ml (range 21-52 pg/ml) within 5-8 hours. The half-life of 17 beta-estradiol is about 12-14 hours. It circulates bound to SHBG (37%) and to albumin (61%), while only approximately 1-2% is unbound. Metabolism of 17 beta-estradiol, occurs mainly in the liver and gut but also in target organs, and involves the formation of less active or inactive metabolites, including estrone, catecholestrogens and several oestrogen sulphates and glucuronides. Oestrogens are excreted with the bile, where they are hydrolysed and reabsorbed (enterohepatic circulation), and mainly in urine in biologically inactive form.



After oral administration norethisterone acetate is rapidly absorbed and transformed to norethisterone (NET). It undergoes first-pass metabolism in the liver and other enteric organs, and reaches a peak plasma concentration of approximately 3.9 ng/ml (range 1.4-6.8 ng/ml) within 0.5-1.5 hour. The terminal half-life of NET is about 8-11 hours. NET binds to SHBG (36%) and to albumin (61%). The most important metabolites are isomers of 5α-dihydro-NET and of tetrahydro-NET, which are excreted mainly in the urine as sulfate or glucuronide conjugates.



The pharmacokinetics in the elderly has not been studied.



5.3 Preclinical Safety Data



Acute toxicity of oestrogens is low. Because of marked differences between animal species and between animals and humans preclinical results possess a limited predictive value for the application of oestrogens in humans.



In experimental animals estradiol or estradiol valerate displayed an embryolethal effect already at relatively low doses; malformations of the urogenital tract and feminisation of male foetuses were observed.



Norethisterone, like other progestagens, caused virilisation of female foetuses in rats and monkeys. After high doses of norethisterone embryolethal effects were observed.



Preclinical data based on conventional studies of repeated dose toxicity, genotoxicity and carcinogenic potential revealed no particular human risks beyond those discussed in other sections of the SPC.
