<prompt> Brinzolamide isCompetitive and reversible carbonic anhydrase inhibitorNon-competitive and reversible carbonic anhydrase inhibitorCompetitive and irreversible carbonic anhydrase inhibitorNon-competitive and irreversible carbonic anhydrase inhibitor  <response>: Carbonic anhydrase CAse is an enzyme which catalyses the reversible reaction H2O CO2 - H2C03 Hence, Carbonic anhydrase functions in CO2 and HC03 transpo and in H ion secretion. Carbonic anhydrase inhibitors act by non-competitive but reversible inhibition of the enzyme -Decreases the production of aqueous humor from ciliary body epithelium. Ex: Acetazolamide, dorzolamide and Brinzolamide.
