    • Chemical Class:

      A carboxylic ester resulting from the formal condensation of (1-hydroxycyclopentyl)(phenyl)acetic acid with <element>N</element>,<element>N</element>-dimethylethanolamine. A tertiary amine antimuscari nic 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 opth almic diagnostic procedures. It acts more quickly than atropine and has a shorter duration of action. ChEBI CHEBI:4024
