Dorzolamide hydrochloride ophthalmic solution is a carbonic anhydrase inhibitor formulated for topical ophthalmic use. Dorzolamide hydrochloride is described chemically as: (4 S-trans )-4-(ethylamino)-5,6-dihydro-6-methyl-4 H -thieno[2,3- b ]thiopyran-2-sulfonamide 7,7-dioxide monohydrochloride. Dorzolamide hydrochloride is optically active. The specific rotation is α 25° (C=1, water) = ~ -17°. 405 Its empirical formula is C 10 H 16 N 2 O 4 S 3 •HCl and its structural formula is: Dorzolamide hydrochloride has a molecular weight of 360.9 and a melting point of about 264°C. It is a white to off-white, crystalline powder, which is soluble in water and slightly soluble in methanol and ethanol. Dorzolamide hydrochloride ophthalmic solution is supplied as a sterile, isotonic, buffered, slightly viscous, aqueous solution of dorzolamide hydrochloride. The pH of the solution is approximately 5.4 to 5.9, and the osmolarity is 260-330 mOsmoles/kg. Each mL of dorzolamide hydrochloride ophthalmic solution 2% contains 20 mg dorzolamide (equivalent to 22.3 mg of dorzolamide hydrochloride). Inactive ingredients are hydroxyethyl cellulose, mannitol, sodium citrate dihydrate, sodium hydroxide (to adjust pH) and water for injection. Benzalkonium chloride 0.0075% is added as a preservative.
