Metabolite Identification
Common NameTropicamide
DescriptionTropicamide is only found in individuals that have used or taken this drug. It is one of the muscarinic antagonists with pharmacologic action similar to atropine and used mainly as an ophthalmic parasympatholytic or mydriatic. [PubChem]Tropicamide binds to and blocks the receptors in the muscles of the eye (muscarinic receptor M4). Tropicamide acts by blocking the responses of the iris sphincter muscle to the iris and ciliary muscles to cholinergic stimulation, producing dilation of the pupil and paralysis of the ciliary muscle.
