Tropicamide/hydroxyamfetamine
Tropicamide/Hydroxyamfetamine
Tropicamide/Hydroxyamfetamine (pronunciation: troh-pi-KA-mide/hy-drox-ee-am-FET-a-meen) is a combination of two drugs used in the field of ophthalmology to dilate the pupil and to test for Horner's syndrome, a rare disorder that affects the eyes and areas of the face.
Etymology
The term 'Tropicamide' is derived from the Greek word 'tropos', meaning 'turn', and 'amide', a common suffix in organic chemistry indicating the presence of an amide group. 'Hydroxyamfetamine', on the other hand, is a compound word formed from 'hydroxy', indicating the presence of a hydroxyl group, and 'amfetamine', a variant spelling of 'amphetamine', a type of stimulant drug.
Usage
Tropicamide is an anticholinergic that works by relaxing the muscles in the eye to allow it to widen (dilate). Hydroxyamfetamine, a sympathomimetic amine, stimulates the release of norepinephrine, a neurotransmitter, which causes the dilation of the pupil.
