Patient summary

Developed to manage glaucoma and oedema to alleviate pressure and reduce fluid retention.

Mechanism of action

Acetazolamide is a carbonic anhydrase inhibitor. By blocking this enzyme in the eye, it reduces the production of aqueous humour, thereby lowering intraocular pressure. It also acts as a mild diuretic by inhibiting bicarbonate reabsorption.
