Uses
INDICATIONS AND USAGE: Phendimetrazine tartrate is indicated in the management of exogenous obesity as a short term adjunct (a few weeks) in a regimen of weight reduction based on caloric restriction in patients with an initial body mass index (BMI) of 30 kg/m 2 or higher who have not responded to appropriate weight reducing regimen (diet and/or exercise) alone. 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 kilograms (kg), divided by the patient’s height, in meters (m), squared. Metric conversions are as follows: pounds ÷ 2.2 = kg; inches x 0.0254 = meters. Phendimetrazine tartrate is indicated for use as monotherapy only. bmi index
Dosage
DOSAGE AND ADMINISTRATION: Usual Adult Dosage: 1 tablet (35 mg) twice a day or three times a day one hour before meals. Dosage should be individualized to obtain an adequate response with the lowest effective dosage. In some cases, ½ tablet (17.5 mg) per dose may be adequate. Dosage should not exceed 2 tablets three times a day.
Side Effects
ADVERSE REACTIONS: Cardiovascular: Palpitations, tachycardia, elevated blood pressure, ischemic events. Valvular heart disease associated with the use of some anorectic agents such as fenfluramine and dexfenfluramine, both independently and especially when used in combination with other anorectic drugs, have been reported. However, no case of this valvulopathy has been reported when phendimetrazine tartrate has been used alone. Central Nervous System: Overstimulation, restlessness, insomnia, agitation, flushing, tremor, sweating, dizziness, headache, psychotic state, blurring of vision. Gastrointestinal: Dryness of the mouth, nausea, diarrhea, constipation, stomach pain. Genitourinary: Urinary frequency, dysuria, changes in libido.
Warnings
WARNINGS: Phendimetrazine tartrate should not be used in combination with other anorectic agents, including prescribed drugs, over-the-counter preparations and herbal products. In a case-control epidemiological study, the use of anorectic agents, including phendimetrazine tartrate, was associated with an increased risk of developing pulmonary hypertension, a rare, but often fatal disorder. The use of anorectic agents for longer than three months was associated with a 23-fold increase in the risk of developing pulmonary hypertension. Increased risk of pulmonary hypertension with repeated courses of therapy cannot be excluded. CONTRAINDICATIONS: Known hypersensitivity or idiosyncratic reactions to sympathomimetics. Advanced arteriosclerosis, symptomatic cardiovascular disease, moderate and severe hypertension, hyperthyroidism, and glaucoma. Highly nervous or agitated patients. Patients with a history of drug abuse. Patients taking other CNS stimulants, including monoamine oxidase inhibitors.
