Actions of Tropicol in details
Tropicol binds to and blocks the receptors in the muscles of the eye (muscarinic receptor M4). Tropicol acts by blocking the responses of the iris sphincter muscle to the iris and ciliary muscles to cholinergic stimulation, producing dilation of the pupil and paralysis of the ciliary muscle.
How should I take Tropicol?
To use:
- First, wash your hands. Tilt the head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the lower eyelid away from the eye to make a space. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed and apply pressure to the inner corner of the eye with your finger for 2 or 3 minutes to allow the medicine to be absorbed by the eye. This is especially important in infants.
- Immediately after using the eye drops, wash your hands to remove any medicine that may be on them. If you are using the eye drops for an infant or child, be sure to wash the infant's or child's hands also, and do not let any of the medicine get in the infant's or child's mouth.
- To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, keep the container tightly closed.
Use Tropicol only as directed. Do not use more of it and do not use it more often than your doctor ordered. To do so may increase the chance of too much medicine being absorbed into the body and the chance of side effects.
Dosing
The dose of Tropicol will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of Tropicol. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Tropicol pharmacology
Tropicol belongs to the group of medicines called anti-muscarinics. Tropicol blocks the receptors in the muscles of the eye (muscarinic receptors). These receptors are involved controlling the pupil size and the shape of the lens. By blocking these receptors, Tropicol produces dilatation of the pupil (mydriasis) and prevents the eye from accommodating for near vision (cycloplegia). Tropicol is given as eye drops to dilate the pupil and relax the lens so that eye examinations can be carried out thoroughly.
