Notes: Dorzolamide-d5 is intended for use as an internal standard for the quantification of dorzolamide (Item No. 14616) by GC- or LC-MS. Dorzolamide is an inhibitor of carbonic anhydrase (CA), inhibiting CAII, CAV, CAVI, CAIX, CAXII, CAXIII, and CAXIV with Ki values ranging from 3.5 to 52 nM.{23433,23435,23434} It is selective for these isoforms over CAI, CAIII, and CAIV (Kis = 50, 8, and 8.5 μM, respectively).{23433} Dorzolamide inhibits carbonic anhydrase in isolated rabbit iris-ciliary body by 87% when used at a concentration of 0.02%.{23434} It also reduces intraocular pressure in an α-chymotrypsin-treated rabbit model of ocular hypertension and in normotensive rabbits when applied topically at a concentration of 0.5%.{23434} Formulations containing dorzolamide have been used in the treatment of glaucoma.{23432,23436}
