Phenmetrazine is described as a stimulant with which typical duration and routes?

• A. Duration: 2-4 hours; Uses: oral/injected
• B. Duration: 8-12 hours; Uses: smoked
• C. Duration: 1-2 hours; Uses: sniffed
• D. Duration: 24-48 hours; Uses: topical

Answer: (A)

The key idea here is matching phenmetrazine’s typical duration of action with plausible routes of administration. Phenmetrazine, a stimulant once used as an appetite suppressant, produces effects that last only a few hours. In pharmacology and clinical profiles, its duration is described around two to four hours, which fits a relatively short-acting stimulant. The common routes consistent with its medical use and misuse patterns are oral ingestion and, less commonly, injection. It is not typically associated with lasting many hours or days, and routes like smoking, sniffing, or topical application do not align with its standard pharmacokinetic and historical misuse patterns. So the option that describes a two-to-four hour duration along with oral or injected use best matches the drug’s pharmacological profile.
