Acetazolamide is a drug that can treat glaucoma, epilepsy, mountain sickness, periodic paralysis, idiopathic intracranial hypertension, and heart failure. It is a diuretic as well, which makes it effective for mountain sickness. Acetazolamide can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particle columns are available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation of impurities in preparative separation. It also suitable for pharmacokinetics.
