Demecarium (HUMORSOL®) is an indirect-acting parasympathomimetic agent, also known as a cholinesterase inhibitor and anticholinesterase. Cholinesterase inhibitors prolong the effect of acetylcholine, which is released at the neuroeffector junction of parasympathetic postganglion nerves, by inactivating the cholinesterases that break it down. Application of demecarium (HUMORSOL®) to the eye produces intense miosis and ciliary muscle contraction due to inhibition of cholinesterase, allowing acetylcholine to accumulate at sites of cholinergic transmission. These effects are accompanied by increased capillary permeability of the ciliary body and iris, increased permeability of the blood-aqueous barrier, and vasodilation. Myopia may be induced or, if present, may be augmented by the increased refractive power of the lens that results from the accommodative effect of the drug. Demecarium (HUMORSOL®) indirectly produces some of the muscarinic and nicotinic effects of acetylcholine as quantities of the latter accumulate.

Sample Use Guides

In Vivo Use Guide

For glaucoma initial therapy with demecarium (HUMORSOL®) place 1 or 2 drops in the glaucomatous eye. The usual dosage can vary from as much as 1 or 2 drops twice a day to as little as 1 or 2 drops twice a week. For treatment of esotropia with demecarium (HUMORSOL®) 1 drop is given daily for 2 weeks, then 1 drop every 2 days for 2 to 3 weeks. In esotropia uncomplicated by amblyopia or anisometropia, demecarium (HUMORSOL®) may be instilled in both eyes, not more than 1 drop at a time every day for 2 to 3 weeks, as too severe a degree of miosis may interfere with vision. Then reduce the dosage to 1 drop every other day for 3 to 4 weeks and reevaluate the patient's status.

Route of Administration: Topical

In Vitro Use Guide

Tetramethoquin and demecarium bromide were compared with physostigmine on the hypogastric guinea-pig nerve-vas deferens preparation. Each drug, in bath concentrations of 1 ug/ml, potentiated the response of the vas deferens to nerve stimulation. Subsequent addition of a higher dose of these agents inhibited the response. With demecarium inhibition occurred with 3 to 5 ug/ml.
