DESCRIPTION
Chemical name: (2-mercaptoethyl) trimethylammonium iodide O,O-diethyl
phosphorothioate
Structural formula

INO PS M.W. 383.23
Echothiophate iodide for ophthalmic solution occurs as a white,
crystalline, water-
soluble, hygroscopic solid having a slight mercaptan-like odor. When
freeze-dried in the
presence of potassium acetate, the mixture appears as a white
amorphous deposit on
the walls of the bottle.
Each package contains materials for dispensing 5 mL of eyedrops: (1)
bottle containing
sterile echothiophate iodide for ophthalmic solution 6.25 mg (0.125%)
with 40 mg
potassium acetate. Sodium hydroxide or acetic acid may have been
incorporated to
adjust pH during manufacturing; (2) a 5 mL bottle of sterile diluent
containing
chlorobutanol (chloral derivative), 0.55%; mannitol, 1.2%; boric acid,
0.06%; and sodium
phosphate, 0.026%; (3) sterilized dropper.
CLINICAL PHARMACOLOGY
Echothiophate iodide for ophthalmic solution is a long-acting
cholinesterase inhibitor for
topical use which enhances the effect of endogenously liberated
acetylcholine in iris,
ciliary muscle, and other parasympathetically innervated structures of
the eye. It thereby
causes miosis, increase in facility of outflow of aqueous humor, fall
in intraocular
pressure (IOP), and potentiation of accommodation.
Echothiophate iodide for ophthalmic solution will depress both plasma
and erythrocyte
cholinesterase levels in most patients after a few weeks of eyedrop
therapy.
