Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzphetamine is a sympathomimetic amine that acts as a central nervous system stimulant. It primarily works by promoting the release of norepinephrine and dopamine from presynaptic nerve terminals in the brain, which leads to appetite suppression and increased energy expenditure.
CNS stimulant; increases extracellular dopamine and norepinephrine levels by blocking their reuptake and enhancing release.
25-50 mg orally once daily, may increase by 25 mg increments at weekly intervals; maximum 100 mg/day.
37.5 mg orally once daily in the morning; may increase by 18.75 mg weekly to a maximum of 112.5 mg/day.

Benzphetamine has a long elimination half-life of 10-16 hours (up to 20 hours in some individuals). Its active metabolites (amphetamine and methamphetamine) have half-lives of 10-12 hours and 9-11 hours, respectively. Steady state is reached within 3-4 days. The long half-life supports once-daily dosing but carries risk of accumulation with renal impairment.
Terminal elimination half-life is 12-30 hours in children (mean 19 hours) and 8-14 hours in adults; the long half-life supports once-daily dosing, but accumulation can occur with repeated dosing
Primarily renal (approximately 70-90% of the dose excreted unchanged in urine, with the remainder as metabolites including amphetamine and methamphetamine). Fecal excretion is minimal (<5%).
Primarily renal (80-90% as unchanged drug and metabolites, with 50-60% as unchanged pemoline), minor biliary/fecal elimination (<10%)
