Metabolite Identification
Common NameCarbachol
DescriptionCarbachol is only found in individuals that have used or taken this drug. It is a slowly hydrolyzed cholinergic agonist that acts at both muscarinic and nicotinic receptors. [PubChem]Carbachol is a parasympathomimetic that stimulates both muscarinic and nicotinic receptors. In topical ocular and intraocular administration its principal effects are miosis and increased aqueous humour outflow.
