MERIDIA (Capsule)
dailymed-instance:dosage
The recommended starting dose of MERIDIA is 10 mg administered once daily with or without food. If there is inadequate weight loss, the dose may be titrated after four weeks to a total of 15 mg once daily. The 5 mg dose should be reserved for patients who do not tolerate the 10 mg dose. Blood pressure and heart rate changes should be taken into account when making decisions regarding dose titration (see WARNINGS andPRECAUTIONS). Doses above 15 mg daily are not recommended. In most of the clinical trials, MERIDIA was given in the morning. Analysis of numerous variables has indicated that approximately 60% of patients who lose at least 4 pounds in the first 4 weeks of treatment with a given dose of MERIDIA in combination with a reduced-calorie diet lose at least 5% (placebo-subtracted) of their initial body weight by the end of 6 months to 1 year of treatment on that doseof MERIDIA. Conversely, approximately 80% of patients who do not lose at least 4 pounds in the first 4 weeks of treatment with a given dose of MERIDIA do not lose at least 5% (placebo-subtracted) of their initial body weight by the end of 6 months to 1 year of treatment on that dose. If a patient has not lost at least 4 pounds in the first 4 weeks of treatment, the physician should consider reevaluation of therapy which may include increasing the dose or discontinuation of MERIDIA. The safety and effectiveness of MERIDIA, as demonstrated in double-blind, placebo-controlled trials, have not been determined beyond 2 years at this time.

Mode of Action: Sibutramine produces its therapeutic effects by norepinephrine, serotonin and dopamine reuptake inhibition. Sibutramine and its major pharmacologically active metabolites (Mand M) do not act via release of monoamines.<br/>Pharmacodynamics: Sibutramine exerts its pharmacological actions predominantly via its secondary (M) and primary (M) amine metabolites. The parent compound, sibutramine, is a potent inhibitor of serotonin (5-hydroxytryptamine, 5-HT) and norepinephrine reuptake in vivo, but not in vitro. However, metabolites Mand Minhibit the reuptake of these neurotransmitters both in vitro and in vivo. In human brain tissue, Mand Malso inhibit dopamine reuptake in vitro, but with ~3-fold lower potency than for the reuptake inhibition of serotonin or norepinephrine. A study using plasma samples taken from sibutramine-treated volunteers showed monoamine reuptake inhibition of norepinephrine>serotonin>dopamine; maximum inhibitions were norepinephrine = 73%, serotonin = 54% and dopamine = 16%. Sibutramine and its metabolites (Mand M) are not serotonin, norepinephrine or dopamine releasing agents. Following chronic administration of sibutramine to rats, no depletion of brain monoamines has been observed. Sibutramine, Mand Mexhibit no evidence of anticholinergic or antihistaminergic actions. In addition, receptor binding profiles show that sibutramine, Mand Mhave low affinity for serotonin (5-HT, 5-HT, 5-HT, 5-HT, 5-HT), norepinephrine (��,��,��,��and��), dopamine (Dand D), benzodiazepine, and glutamate (NMDA) receptors. These compounds also lack monoamine oxidase inhibitory activity in vitro and in vivo.<br/>Pharmacokinetics:<br/>Absorption: Sibutramine is rapidly absorbed from the GI tract (Tof 1.2 hours) following oral administration and undergoes extensive first-pass metabolism in the liver (oral clearance of 1750 L/h and half-life of 1.1 h) to form the pharmacologically active mono- and di-desmethyl metabolites Mand M. Peak plasma concentrations of Mand Mare reached within 3 to 4 hours. On the basis of mass balance studies, on average, at least 77% of a single oral dose of sibutramine is absorbed. The absolute bioavailability of sibutramine has not been determined.<br/>Distribution: Radiolabeled studies in animals indicated rapid and extensive distribution into tissues: highest concentrations of radiolabeled material were found in the eliminating organs, liver and kidney. In vitro, sibutramine, Mand Mare extensively bound (97%, 94% and 94%, respectively) to human plasma proteins at plasma concentrations seen following therapeutic doses.<br/>Metabolism: Sibutramine is metabolized in the liver principally by the cytochrome P450 (3A) isoenzyme, to desmethyl metabolites, Mand M. These active metabolites are further metabolized by hydroxylation and conjugation to pharmacologically inactive metabolites, Mand M. Following oral administration of radiolabeled sibutramine, essentially all of the peak radiolabeled material in plasma was accounted for by unchanged sibutramine (3%), M(6%), M(12%), M(52%), and M(27%). Mand Mplasma concentrations reached steady-state within four days of dosing and were approximately two-fold higher than following a single dose. The elimination half-lives of Mand M, 14 and 16 hours, respectively, were unchanged following repeated dosing.<br/>Excretion: Approximately 85% (range 68-95%) of a single orally administered radiolabeled dose was excreted in urine and feces over a 15-day collection period with the majority of the dose (77%) excreted in the urine. Major metabolites in urine were Mand M; unchanged sibutramine, M, and Mwere not detected. The primary route of excretion for Mand Mis hepatic metabolism and for Mand Mis renal excretion.<br/>Effect of Food: Administration of a single 20 mg dose of sibutramine with a standard breakfast resulted in reduced peak Mand Mconcentrations (by 27% and 32%, respectively) and delayed the time to peak by approximately three hours. However, the AUCs of Mand Mwere not significantly altered.<br/>Special Populations:<br/>Drug-Drug Interactions: In vitro studies indicated that the cytochrome P450 (3A)-mediated metabolism of sibutramine was inhibited by ketoconazole and to a lesser extent by erythromycin. Phase 1 clinical trials were conducted to assess the interactions of sibutramine with drugs that are substrates and/or inhibitors of various cytochrome P450 isozymes. The potential for studied interactions is described below.

Pulmonary Hypertension: Certain centrally-acting weight loss agents that cause release of serotonin from nerve terminals have been associated with pulmonary hypertension (PPH), a rare but lethal disease. In premarketing clinical studies, no cases of PPH have been reported with sibutramine capsules. Because of the low incidence of this disease in the underlying population, however, it is not known whether or not MERIDIA may cause this disease.<br/>Seizures: During premarketing testing, seizures were reported in<0.1% of sibutramine treated patients. MERIDIA should be used cautiously in patients with a history of seizures. It should be discontinued in any patient who develops seizures.<br/>Bleeding: There have been reports of bleeding in patients taking sibutramine. While a causal relationship is unclear, caution is advised in patients predisposed to bleeding events and those taking concomitant medications known to affect hemostasis or platelet function.<br/>Gallstones: Weight loss can precipitate or exacerbate gallstone formation.<br/>Renal Impairment: MERIDIA should be used with caution in patients with mild to moderate renal impairment. MERIDIA should not be used in patients with severe renal impairment, including those with end stage renal disease on dialysis (see Pharmacokinetics-Special Populations-Renal Insufficiency).<br/>Hepatic Dysfunction: Patients with severe hepatic dysfunction have not been systematically studied; MERIDIA should therefore not be used in such patients.<br/>Interference With Cognitive and Motor Performance: Although sibutramine did not affect psychomotor or cognitive performance in healthy volunteers, any CNS active drug has the potential to impair judgment, thinking or motor skills.<br/>Information For Patients: Physicians should instruct their patients to read the patient package insert before starting therapy with MERIDIA and to reread it each time the prescription is renewed. Physicians should also discuss with their patients any part of the package insert that is relevant to them. In particular, the importance of keeping appointments for follow-up visits should be emphasized. Patients should be advised to notify their physician if they develop a rash, hives, or other allergic reactions. Patients should be advised to inform their physicians if they are taking, or plan to take, any prescription or over-the-counter drugs, especially weight-reducing agents, decongestants, antidepressants, cough suppressants, lithium, dihydroergotamine, sumatriptan (Imitrex), or tryptophan, since there is a potential for interactions. Patients should be reminded of the importance of having their blood pressure and pulse monitoredat regular intervals.<br/>Drug Interactions:<br/>CNS Active Drugs:: The use of MERIDIA in combination with other CNS-active drugs, particularly serotonergic agents, has not been systematically evaluated. Consequently, caution is advised if the concomitant administration of MERIDIA with other centrally-acting drugs is indicated (see CONTRAINDICATIONS and WARNINGS). In patients receiving monoamine oxidase inhibitors (MAOIs) (e.g., phenelzine, selegiline) in combination with serotonergic agents (e.g., fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine), there have been reports of serious, sometimes fatal, reactions ("serotonin syndrome;" see below). Because sibutramine inhibits serotonin reuptake,MERIDIA should not be used concomitantly with a MAOI (see CONTRAINDICATIONS ). At least 2 weeks should elapse between discontinuation of a MAOI and initiation of treatment with MERIDIA. Similarly, at least 2 weeks should elapse between discontinuation of MERIDIA and initiation of treatment with a MAOI. The rare, but serious, constellation of symptoms termed "serotonin syndrome" has also been reported with the concomitant use of selective serotonin reuptake inhibitors and agents for migraine therapy, such as Imitrex (sumatriptan succinate) and dihydroergotamine, certain opioids, such as dextromethorphan, meperidine, pentazocine and fentanyl, lithium, or tryptophan. Serotonin syndrome has also been reported with the concomitant use of two serotonin reuptake inhibitors. The syndrome requires immediate medical attention and may include one or more of the following symptoms: excitement, hypomania, restlessness, loss of consciousness, confusion, disorientation, anxiety, agitation, motorweakness, myoclonus, tremor, hemiballismus, hyperreflexia, ataxia, dysarthria, incoordination, hyperthermia, shivering, pupillary dilation, diaphoresis, emesis, and tachycardia. Because sibutramine inhibits serotonin reuptake, in general, it should not be administered with other serotonergic agents such as those listed above. However, if such a combination is clinically indicated, appropriate observation of the patient is warranted.<br/>Drugs That May Raise Blood Pressure and/or Heart Rate: Concomitant use of MERIDIA and other agents that may raise blood pressure or heart rate have not been evaluated. These include certain decongestants, cough, cold, and allergy medications that contain agents such as ephedrine, or pseudoephedrine. Caution should be used when prescribing MERIDIA to patients who use these medications.<br/>Alcohol: In a double-blind, placebo-controlled, crossover study in 19 volunteers, administration of a single dose of ethanol (0.5 mL/kg) together with 20 mg of sibutramine resulted in no psychomotor interactions of clinical significance between alcohol and sibutramine. However, the concomitant use of MERIDIA and excess alcohol is not recommended.<br/>Oral Contraceptives: The suppression of ovulation by oral contraceptives was not inhibited by sibutramine. In a crossover study, 12 healthy female volunteers on oral steroid contraceptives received placebo in one period and 15 mg sibutramine in another period over the course of 8 weeks. No clinically significant systemic interaction was observed; therefore, no requirement for alternative contraceptive precautions are needed when patients taking oral contraceptives are concurrently prescribed sibutramine.<br/>Carcinogenesis, Mutagenesis, Impairment of Fertility:<br/>Carcinogenicity: Sibutramine was administered in the diet to mice (1.25, 5 or 20 mg/kg/day) and rats (1, 3, or 9 mg/kg/day) for two years generating combined maximum plasma AUC's of the two major active metabolites equivalent to 0.4 and 16 times, respectively, those following a daily human dose of 15 mg. There was no evidence of carcinogenicity in mice or in female rats. In male rats there was a higher incidence of benign tumors of the testicular interstitial cells; such tumors are commonly seen in rats and are hormonally mediated. The relevance of these tumors to humans is not known.<br/>Mutagenicity: Sibutramine was not mutagenic in the Ames test, in vitro Chinese hamster V79 cell mutation assay, in vitro clastogenicity assay in human lymphocytes or micronucleus assay in mice. Its two major active metabolites were found to have equivocal bacterial mutagenic activity in the Ames test. However, both metabolites gave consistently negative results in the in vitro Chinese hamster V79 cell mutation assay, in vitro clastogenicity assay in human lymphocytes, in vitro DNA-repair assay in HeLa cells, micronucleus assay in mice and in vivo unscheduled DNA-synthesis assay in rat hepatocytes.<br/>Impairment of Fertility: In rats, there were no effects on fertility at doses generating combined plasma AUC's of the two major active metabolites up to 32 times those following a human dose of 15 mg. At 13 times the human combined AUC, there was maternal toxicity, and the dams' nest-building behavior was impaired, leading to a higher incidence of perinatal mortality; there was no effect at approximately 4 times the human combined AUC.<br/>Pregnancy:<br/>Teratogenic Effects:<br/>Nursing Mothers: It is not known whether sibutramine or its metabolites are excreted in human milk. MERIDIA is not recommended for use in nursing mothers. Patients should be advised to notify their physician if they are breast-feeding.<br/>Pediatric Use: The efficacy of sibutramine in adolescents who are obese has not been adequately studied. Sibutramine's mechanism of action inhibiting the reuptake of serotonin and norepinephrine is similar to the mechanism of action of some antidepressants. Pooled analyses of short-term placebo-controlled trials of antidepressants in children and adolescents with major depressive disorder (MDD), obsessive compulsive disorder (OCD), and other psychiatric disorders have revealed a greater risk of adverse events representing suicidal behavior or thinking during the first few months of treatment in those receiving antidepressants. The average risk of such events in patients receiving antidepressants was 4%, twice the placebo risk of 2%. No placebo-controlled trials of sibutramine have been conducted in children or adolescents with MDD, OCD, or other psychiatric disorders. In a study of adolescents with obesity in which 368 patients were treated with sibutramine and 130 patients with placebo, one patient in the sibutramine group and one patient in the placebo group attempted suicide. Suicidal ideation was reported by 2 sibutramine-treated patients and none of the placebo patients. It is unknown if sibutramine increases the risk of suicidal behavior or thinking inpediatric patients. The data are inadequate to recommend the use of sibutramine for the treatment of obesity in pediatric patients.<br/>Geriatric Use: Clinical studies of sibutramine did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Pharmacokinetics in elderly patients are discussed in "CLINICAL PHARMACOLOGY."
dailymed-instance:overdosag...
Overdose Management: There is limited experience of overdose with sibutramine. The most frequently noted adverse events associated with overdose are tachycardia, hypertension, headache and dizziness. Treatment should consist of general measures employed in the management of overdosage: an airway should be established as needed; cardiac and vital sign monitoring is recommended; general symptomatic and supportive measures should be instituted. Cautious use of��-blockers may be indicated to control elevated blood pressure or tachycardia. The results from a study in patients with end-stage renal disease on dialysis showed that sibutramine metabolites were not eliminated to a significant degree with hemodialysis. (see Pharmacokinetics-Special Populations-Renal Insufficiency).

In placebo-controlled studies, 9% of patients treated with sibutramine (n = 2068) and 7% of patients treated with placebo (n = 884) withdrew for adverse events. In placebo-controlled studies, the most common events were dry mouth, anorexia, insomnia, constipation and headache. Adverse events in these studies occurring in���1% of sibutramine treated patients and more frequently than in the placebo group are shown in the following table. The following additional adverse events were reported in���1% of all patients who received sibutramine in controlled and uncontrolled premarketing studies.<br/>Body as a Whole: fever.<br/>Digestive System: diarrhea, flatulence, gastroenteritis, tooth disorder.<br/>Metabolic and Nutritional: peripheral edema.<br/>Musculoskeletal System: arthritis.<br/>Nervous System: agitation, leg cramps, hypertonia, thinking abnormal.<br/>Respiratory System: bronchitis, dyspnea.<br/>Skin and Appendages: pruritus.<br/>Special Senses: amblyopia.<br/>Urogenital System: menstrual disorders.<br/>Other Adverse Events:<br/>Clinical Studies:<br/>Postmarketing Reports: Voluntary reports of adverse events temporally associated with the use of sibutramine are listed below. It is important to emphasize that although these events occurred during treatment with sibutramine, they may have no causal relationship with the drug. Obesity itself, concurrent disease states/risk factors, or weight reduction may be associated with an increased risk for some of these events.<br/>Psychiatric: Cases of depression, suicidal ideation and suicide have been reported rarely in patients on sibutramine treatment. However, a relationship has not been established between the occurrence of depression and/or suicidal ideation and the use of sibutramine. If depression occurs during treatment with sibutramine, further evaluation may be necessary.<br/>Hypersensitivity: Allergic hypersensitivity reactions ranging from mild skin eruptions and urticaria to angioedema and anaphylaxis have been reported (see CONTRAINDICATIONS and PRECAUTIONS-Information For Patients, and other reports of allergic reactions listed below).<br/>Other Postmarketing Reported Events::
dailymed-instance:warning
Blood Pressure and Pulse: MERIDIA SUBSTANTIALLY INCREASES BLOOD PRESSURE AND/OR PULSE RATE IN SOME PATIENTS. REGULAR MONITORING OF BLOOD PRESSURE AND PULSE RATE IS REQUIRED WHEN PRESCRIBING MERIDIA. In placebo-controlled obesity studies, sibutramine 5 to 20 mg once daily was associated with mean increases in systolic and diastolic blood pressure of approximately 1 to 3 mm Hg relative to placebo, and with mean increases in pulse rate relative to placebo of approximately 4 to 5 beats per minute. Larger increases were seen in some patients, particularly when therapy with sibutramine was initiated at the higher doses (see table below). In premarketing placebo-controlled obesity studies, 0.4% of patients treated with sibutramine were discontinued for hypertension (SBP���160 mm Hg or DBP���95 mm Hg), compared with 0.4% in the placebo group, and 0.4% of patients treated with sibutramine were discontinued for tachycardia (pulse rate���100 bpm), compared with 0.1% in the placebo group. Blood pressure and pulse should be measured prior to starting therapy with MERIDIA and should be monitored at regular intervals thereafter. For patients who experience a sustained increase in blood pressure or pulse rate while receiving MERIDIA, either dose reduction or discontinuation should be considered. MERIDIA should be given with caution to those patients with a history of hypertension (see DOSAGE AND ADMINISTRATION), and should not be given to patients with uncontrolled or poorly controlled hypertension.<br/>Potential Interaction With Monoamine Oxidase Inhibitors: MERIDIA is a norepinephrine, serotonin and dopamine reuptake inhibitor and should not be used concomitantly with MAOIs (see PRECAUTIONS, Drug Interactions subsection). There should be at least a 2-week interval after stopping MAOIs before commencing treatment with MERIDIA. Similarly, there should be at least a 2-week interval after stopping MERIDIA before starting treatment with MAOIs.<br/>Concomitant Cardiovascular Disease: MERIDIA substantially increases blood pressure and/or pulse rate in some patients. Therefore, MERIDIA should not be used in patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke.<br/>Glaucoma: Because MERIDIA can cause mydriasis, it should be used with caution in patients with narrow angle glaucoma.<br/>Miscellaneous: Organic causes of obesity (e.g., untreated hypothyroidism) should be excluded before prescribing MERIDIA.
dailymed-instance:indicatio...
MERIDIA is indicated for the management of obesity, including weight loss and maintenance of weight loss, and should be used in conjunction with a reduced calorie diet. MERIDIA is recommended for obese patients with an initial body mass index���30 kg/m, or���27 kg/min the presence of other risk factors (e.g., diabetes, dyslipidemia, controlled hypertension). Below is a chart of Body Mass Index (BMI) based on various heights and weights. BMI is calculated by taking the patient's weight, in kg, and dividing by the patient's height, in meters, squared. Metric conversions are as follows: pounds��2.2 = kg; inches��0.0254 = meters.
