HIDE SMILES / InChI
Benzphetamine is a sympathomimetic agent with properties similar to dextroamphetamine. It is used in the management of exogenous obesity as a short term (a few weeks) adjunct in a regimen of weight reduction based on caloric restriction in patients with an initial body mass index (BMI) of 30 kg/m2 or higher who have not responded to appropriate weight reducing regimen (diet and/or exercise) alone. Presumably, benzphetamine produces its effects through mechanisms similar to amphetamine via induces synaptic vesicular amine transporter, but precise mechanism of action of benzphetamine is not known.

Sample Use Guides

Dosage should be individualized according to the response of the patient. The suggested dosage ranges from 25 to 50 mg one to three times daily. Treatment should begin with 25 to 50 mg once daily with subsequent increase in individual dose or frequency according to response. A single daily dose is preferably given in mid-morning or mid-afternoon, according to the patient's eating habits. In an occasional patient it may be desirable to avoid late afternoon administration. Use of benzphetamine hydrochloride is not recommended in individuals under 12 years of age.
