Dilate Eye Drops(Tropicamide 1%)

Therapeutic Group: Ophthalmic


Dilate 1 % Eye Drops: Each ml contains 10 mg Tropicamide BP


Dilate Eye Drops is an anticholinergic, prepared as a sterile topical ophthalmic solution. This anticholinergic preparation blocks the responses of the sphincter muscle of the iris and the ciliary muscle to cholinergic stimulation, dilating the pupil (mydriasis). The stronger preparation (1%) also paralyzes accommodation. This preparation acts in 15-30 minutes and the duration of activity is approximately 3-8 hours. Complete recovery from mydriasis in some individuals may require 24 hours. The weaker strength may be useful in producing mydriasis with only slight cycloplegia. Heavily pigmented irides may require more doses than lightly pigmented irides.


For mydriasis and cycloplegia for diagnostic procedure, for the treatment of acute and subacute iridocyclitis, chronic iridocyclitis, Adhesions and disruptions of iris and ciliary body, Sclera and iris operations

Dosage & Administration

For refraction, instill one or two drops of 1% solution in the eye(s), repeated in five minutes. If patient is not seen within 20 to 30 minutes, an additional drop may be instilled to prolong mydriatic effect. For examination of fundus, instill one or two drops of 0.5% solution 15 to 20 minutes prior to examination. Individuals with heavily pigmented irides may require higher strength or more doses.

Dryness of the mouth, tachycardia, headache, allergic reactions, nausea, vomiting, pallor, central nervous system disturbances and muscle rigidity have been reported with the use of tropicamide.


The lacrimal sac should be compressed by digital pressure for 2-3 minutes after instillation to avoid excessive systemic absorption.
