Overview
Phendimetrazine tartrate, as the dextro isomer, has the chemical name of (2 s ,3 s ,)-3,4-dimethyl-2-phenylmorpholine L-(+)-tartrate (1:1). The structural formula is as follows: Phendimetrazine tartrate is a white, odorless crystalline powder. It is freely soluble in water; sparingly soluble in warm alcohol; insoluble in chloroform, acetone, ether and benzene. Each tablet, for oral administration, contains 35 mg of phendimetrazine tartrate. Inactive Ingredients: confectioner’s sugar (sucrose and corn starch), lactose monohydrate, povidone, pregelatinized starch, silicon dioxide and stearic acid. The yellow tablets also contain: FD&C yellow No. 5 (see PRECAUTIONS ).
Indications & Usage
Phendimetrazine tartrate tablets are 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. The limited usefulness of agents of this class (see CLINICAL PHARMACOLOGY ) should be measured against possible risk factors inherent in their use such as those described below.
Dosage & Administration
Usual Adult Dose: 1 tablet (35 mg) b.i.d. or t.i.d., one hour before meals. Dosage should be individualized to obtain an adequate response with the lowest effective dosage. In some cases 1/2 tablet (17.5 mg) per dose may be adequate. Dosage should not exceed 2 tablets t.i.d.
Warnings & Precautions
WARNINGS Tolerance to the anorectic effect of phendimetrazine develops within a few weeks. When this occurs, its use should be discontinued; the maximum recommended dose should not be exceeded. Use of phendimetrazine tartrate within 14 days following the administration of monoamine oxidase inhibitors may result in a hypertensive crisis. Abrupt cessation of administration following prolonged high dosage results in extreme fatigue and depression. Because of the effect on the central nervous system, phendimetrazine may impair the ability of the patient to engage in potentially hazardous activities such as operating machinery or driving a motor vehicle; the patient should therefore be cautioned accordingly.
