Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetazolamide is a carbonic anhydrase inhibitor. It reversibly inhibits the enzyme carbonic anhydrase, which catalyzes the reversible hydration of carbon dioxide and dehydration of carbonic acid. This results in increased excretion of bicarbonate, sodium, potassium, and water in the urine, leading to metabolic acidosis. Additionally, it reduces aqueous humor secretion in the eye, lowering intraocular pressure, and can decrease cerebrospinal fluid production.
Carbonic anhydrase inhibitor. Inhibits carbonic anhydrase in the proximal renal tubule, reducing bicarbonate reabsorption and causing alkaline diuresis.
Adult: 250-500 mg IV or IM every 12-24 hours; for edema, 250-375 mg IV once daily in morning. For glaucoma, 250-1000 mg IV or IM daily in divided doses.
50 mg orally once or twice daily; maximum 100 mg/day.

10-15 hours (prolonged in renal impairment; cirrhosis increases t1/2 to 20-30 h).
Terminal elimination half-life: 2.5-3.5 hours (prolonged in renal impairment). Clinical context: Short half-life necessitates multiple daily dosing for sustained diuretic effect.
Primarily renal (90% unchanged via tubular secretion). <2% biliary/fecal.
Renal: unchanged drug (approximately 50% of absorbed dose) and metabolites. Biliary/fecal: minimal.
