Miotic agents

Contract ciliary muscle, tightening the trabecular meshwork and allowing increased outflow of the aqueous. Miosis results from action of these drugs on pupillary sphincter. Adverse effects include brow ache, induced myopia, and decreased vision in low light.

Pilocarpine ophthalmic (Isopto Carpine)

A naturally occurring alkaloid, pilocarpine mimics muscarinic effects of acetylcholine at postganglionic parasympathetic nerves. Directly stimulates cholinergic receptors in the eye, decreasing resistance to aqueous humor outflow.

Instillation frequency and concentration are determined by patient's response. Individuals with heavily pigmented irides may require higher strengths. If other glaucoma medication is also being used, at bedtime, use gtt at least 5 min before gel. May use alone, or in combination with other miotics, beta-adrenergic blocking agents, epinephrine, carbonic anhydrase inhibitors, or hyperosmotic agents to decrease IOP.
