Pharmacological properties
Pharmacodynamics
Dorzolamide is one of the antiglaucoma drugs. Carbonic anhydrase inhibitor; reduces the secretion of intraocular fluid by slowing down the formation of bicarbonate, followed by weakening the transfer of water and Na +. Miosis, spasm of accommodation and hemeralopia does not cause.
Pharmacokinetics
Dorzolamide penetrates into the eye, mainly through the cornea (through the sclera or limbus - to a lesser extent). Has low systemic absorption. It quickly penetrates into red blood cells after entering the bloodstream.
The connection with plasma proteins is 33%.
It is transformed into an N-desethylated metabolite, which exhibits less activity against carbonic anhydrase II, but retains the ability to block carbonic anhydrase I. With prolonged use, it accumulates in erythrocytes.
It is excreted in the form of metabolites and unchanged by the kidneys. After the cancellation of therapy, the slow phase of elimination is replaced by the fast one, which is due to the gradual release of the substance from the erythrocytes. The half-life is approximately 4 months.
