We offer no GRADED recommendations regarding patient suitability, indication suitability or the suitability, safety or efficacy of any dosing protocol.
Dosing Suggestion(s)
Glaucoma: 4-10 mg/kg, PO, q8-12h (Whilst intraocular pressure is elevated). It is used in rabbits with glaucoma and as a major species extrapolation (MSE) (Loftsson et al., 1994).
Therapeutics
About Acetazolamide
Acetazolamide is a first-generation carbonic anhydrase inhibitor (CAI) with both diuretic and anti-glaucoma effects (Farzam and Abdullah, 2022).
Ocular effects: Within the eye, CAIs decrease the formation of aqueous humor and reduce intraocular pressure (IOP) (Farzam and Abdullah, 2022).
Diuresis: Acetazolamide increases tubular secretion of bicarbonate alongside sodium and potassium cations and promotes alkaline diuresis (Farzam and Abdullah, 2022).
