Which dosage form is Schedule V?

• A. A dosage unit with not more than 1 mg Difenoxin per dosage unit
• B. A dosage unit with not more than 2.5 mg Diphenoxylate per dosage unit
• C. Ephedrine
• D. Sibutramine

Answer: (B)

Schedule V includes preparations that contain only small amounts of certain narcotics per dosage unit, making abuse risk relatively low. The classic example is a dosage unit with not more than 2.5 mg of diphenoxylate per unit, typically combined with atropine to discourage misuse. That precise limit defines a Schedule V product, so the option describing a dosage unit with not more than 2.5 mg of diphenoxylate per dosage unit is the correct one. Ephedrine is regulated differently as a List I chemical used to manufacture meth, not a Schedule V narcotic preparation. Sibutramine was never a Schedule V controlled substance; it was removed from the market and is not scheduled. A dosage unit with not more than 1 mg of difenoxin per dosage unit falls outside the specific diphenoxylate threshold that places products in Schedule V, and difenoxin has its own scheduling distinctions.
