Metabolite Identification
Common NameCyclopentolate
DescriptionCyclopentolate, also known as bell pentolate or cyclogyl, belongs to the class of organic compounds known as benzene and substituted derivatives. These are aromatic compounds containing one monocyclic ring system consisting of benzene. Cyclopentolate is a drug which is used mainly to produce mydriasis and cycloplegia for diagnostic purposes. Cyclopentolate is a very strong basic compound (based on its pKa). It acts more quickly than atropine and has a shorter duration of action. A tertiary amine antimuscarinic with actions similar to atropine, it is used as its hydrochloride salt to produce mydriasis (excessive dilation of the pupil) and cycloplegia (paralysis of the ciliary muscle of the eye) for opthalmic diagnostic procedures. A carboxylic ester resulting from the formal condensation of (1-hydroxycyclopentyl)(phenyl)acetic acid with N,N-dimethylethanolamine.
