Carbachol 2. Therapeutic uses:

2. Therapeutic uses: Because of its high potency, receptor nonselectivity, and relatively long duration of action, carbachol is rarely used therapeutically except in the eye as a miotic agent to treat glaucoma by causing pupillary contraction and a decrease in intraocular pressure. Onset of action for miosis is 10 to 20 minutes. Intraocular pressure is reduced for 4 to 8 hours.
