This product is composed of tropicamide and phenylephrine hydrochloride. Tropicamide has atropine-like parasympathetic nerve inhibitory effect, which can cause mydriasis and accommodation paralysis after drug absorption, while phenylephrine hydrochloride has sympathetic nerve excitatory effect, which manifests as mydriasis and local vasoconstriction after absorption.

Each bottle contains 25 mg of tropicamide and 25 mg of phenylephrine hydrochloride.

This product is a colorless or slightly yellow clear liquid.

Generally, 0.5% tropicamide and 0.5% phenylephrine hydrochloride mixed eye drops are commonly used in clinical practice. The combination of the two drugs has a synergistic mydriasis effect, reduces the dosage of the drug and reduces adverse reactions. 1. Mydriasis examination: This product is dripped into the conjunctival sac, 1 drop at a time, and the second drop is dripped after an interval of 5 minutes. This product begins to dilate the pupil 5 to 10 minutes after eye drops, and the pupil is dilated to the maximum in 15 to 20 minutes. After about an hour and a half, the pupil begins to shrink, and the pupil returns to the level before the drop of the drug in 5 to 10 hours. 2. Refractive examination: Use this product to drip into the eye once every 5 minutes, for 4 consecutive drops, and a refractive examination can be performed after 20 minutes. Considering the existence of residual accommodation, it is not suitable for mydriasis optometry for children under 12 years old.
