White crystalline hygroscopic powder. Very easily soluble in water, it is difficult - in alcohol.

Pharmacology

Pharmacological action - antiglaucoma.

Unlike acetylcholine, it is not hydrolyzed by true cholinesterase, which is why the effect is more prolonged. When instilled in the eye, the pupil narrows (miosis develops after 15-20 minutes and lasts 4-8 hours), increases the clearance of the fountain spaces and the helmet channel, reduces intraocular pressure (the pressure drop begins in 20-30 minutes and reaches a maximum after 2-3 hours ). Hydroxyethyl cellulose, as a rule, is part of the preparations, contributes to better penetration of carbachol through the cornea. It binds to the m- and n-cholinergic receptors of the postsynaptic membrane of the cholinergic synapses and excites them, simulating the effect of the mediator (acetylcholine).
