Which statement correctly identifies acetazolamide dosage formulations?

• A. There are 125 mg and 500 mg ER formulations
• B. There are only 125 mg tablets
• C. There is no ER formulation
• D. There are 750 mg doses as standard

Answer: (A)

Acetazolamide comes in more than one dosage form to balance how quickly the drug works with how tolerable it is for patients. The correct statement reflects that there are 125 mg tablets and a 500 mg extended-release form. The 125 mg tablets provide immediate release, useful for initial dosing and titration. The 500 mg extended-release formulation delivers the drug over a longer period, giving steadier levels and often better tolerability and adherence, which is helpful in chronic conditions like glaucoma. A 750 mg dose isn’t a standard formulation, and there are more than just 125 mg tablets with an ER option, so that choice isn’t correct.
