描述 Methazolamide (L584601) is a sulfonamide derivative used as a carbonic anhydrase inhibitor with a Ki of 14 nM for human carbonic anhydrase II[3]. Methazolamide is an intraocular pressure-lowering drug that is used in the treatment of glaucoma and other ophthalmologic abnormalities[4]. Methazolamide can increase systemic metabolic acidosis and sequentially improve ventilation and oxygenation level. In addition to the effect as a carbonic anhydrase inhibitor, methazolamide directly activates the transcription factor anti-oxidative nuclear factor-related factor 2 (Nrf2) and inhibits interleukin-1β (IL-1β) release. Methazolamide may thus represent an alternative for acetazolamide when taken for high-altitude illnesses prophylaxis and treatment[5]. Methazolamide exhibits dose-dependent efficacy for the treatment of excessive erythrocytosis induced by long-term hypoxia[6].
