Description

Dorzolamide Hcl(L671152 Hcl; MK507 Hcl) is an anti-glaucoma agent, which is a carbonic anhydrase inhibitor.Target: carbonic anhydrase (CA)Dorzolamide hydrochloride is a carbonic anhydrase inhibitor. It is an anti-glaucoma agent, and acts by decreasing the production of aqueous humour [1]. Glaucoma was induced in the right eye of adult Wistar rats by episcleral venous occlusion. One experimental group was administered dorzolamide hydrochloride 2%-timolol 0.5% combination eye drops, while

Dorzolamide hydrochloride Use and Manufacturing

Methods of Manufacturing

(4S-trans)-4-(N-ethylamino)-5, 6-dihydro-6-methyl-4H-thien-(2, 3-b)-thiopyran-2-sulfonamide-7, 7-dioxide Hydrochloride [0145] [CHEMMOL-00030] [0146] 0.55 g (0.0017 mol) of (4S-trans)-4-(N-ethylamino)-5, 6-dihydro-6-methyl-4H-thien-(2, 3-b)-thiopyran-2-sulfonamide-7, 7-dioxide are dissolved in 25 ml of ethyl acetate, and the pH is set to 1 with hydrochloric acid. The crude product is concentrated to dryness obtaining 0.62 g (95percent) of the title product with a rotary power of [α]D=-8.3° (c=1, methanol).Example 7 Preparation of 5, 6-Dihydro-4H-4-ethylamino-6-methylthieno[2, 3-b]thiopyran-2- sulfonamide-7, 7-dioxide hydrochloride(a) Dorzolamide di-p-toluyl-L-tartrate salt as prepared in example 6 (44.26 gms, 0.085 moles) was taken in ethyl acetate (557.0 ml), basified with saturated sodium bicarbonate solution. Reaction mass was stirred for 15 minutes at 25°C to 3O
