<prompt> Brinzolamide is aHighly specific irreversible and noncompetitive carbonic anhydrase inhibitorHighly specific irreversible and competitive carbonic anhydrase inhibitor.Highly specific reversible and competitive carbonic anhydrose inhibitorHighly specific reversible and non-competitive carbonic anhydrase inhibitor.  <response>: Ans is d i.e. Highly specific reversible and noncompetitive carbonic anhydrase inhibitor o Carbonic anhydrase inhibitors act by a non-competitive, reversible inhibition of the enzyme carbonic anhydrase. o Brinzolamide is a highly .specific inhibitor of carbonic anhydrase II CA II, which is the main carbonic anhydrase isoenzyme involved in the secretion of aqueous humour. o Inhibition caused by brinzolamide is reversible and non-competitive.
