Clinical Utility

Acetazolamide is a potent inhibitor of carbonic anhydrase. It is used in the treatment of glaucoma, mountain sickness (e.g., headache, nausea, dizziness, drowsiness, fatigue, and shortness of breath), and as an antiepileptic and diuretic. This assay is used for the therapeutic monitoring and toxicity assessment of Acetazolamide.
