Pilo Drop Ophthalmic Solution

Pilocarpine is indicated for chronic open angle glaucoma, acute or chronic narrow angle glaucoma, suspected glaucoma and ocular hypertension.

Pilocarpine Hydrochloride directly stimulates cholinergic receptors. It produces contraction of the iris sphincter muscle, resulting in pupillary constriction (miosis); constriction of the ciliary muscle, resulting in increased accommodation; and reduction in intraocular pressure associated with an increase in the outflow and a decrease in the inflow of aqueous humor. In chronic open angle glaucoma, the exact mechanism by which miotics lower intraocular pressure is not exactly known; however, contraction of the ciliary muscle apparently opens the intertrabecular spaces and facilitates aqueous humor outflow. There is also a decrease in the rate of inflow of aqueous humor. In angle-closure glaucoma, constriction of the pupil apparently pulls the iris away from the trabeculum, thereby relieving blockage of the trabecular meshwork.

Instill 1 drop 2-4 times daily. To minimize systemic absorption of the active ingredient of the eye drops, pressure should be applied for one minute on the tear duct after application.

Belladonna alkaloids or cyclopentolate used ophthalmically may interfere with the miotic effects of pilocarpine and may have their own mydriatic effects dampened. This latter may be used to therapeutic advantage.

Hypersensitivity to any ingredient including excipients. Conditions where pupillary constriction is undesirable (e.g. acute iritis). Retinal detachment; past history of retinal detachment or conditions that predispose to retinal detachment.

Common: Temporary blurred vision, burning, stinging, redness, watering of the eyes, decrease in night vision, eye irritation, headache.

Rare: Eye pain, increased sweating, muscle tremors, nausea, vomiting, diarrhea, watering of the mouth, troubled breathing or wheezing.

Safe use during pregnancy has not been established. Problems in human pregnancy have not been documented. However, ophthalmic Pilocarpine is systemically absorbed.

If blurred vision or changes in near or far sight occur, especially at night, patients should exercise caution when involved in night driving or hazardous work in poor light. It is recommended that intraocular pressure measurements be performed regularly during therapy.

Dilution with water and other fluids is the usual response to accidental or deliberate overdose.

Drugs affecting exocrine secretions.

Store at room temperature and protect from light. It is desirable that the contents should not be used more than 4 weeks after first opening of the bottle.
