シクロペントラート塩酸塩

説明Cyclopentolate is an antagonist of muscarinic acetylcholine receptors (Kis = 1.62, 27.5, and 2.63 nM for M1, M2, and M3 receptors, respectively). It inhibits carbachol-induced contraction of isolated human iris sphincter, circular ciliary muscle, and longitudinal ciliary muscle (Kbs = 7.9, 15.8, and 12.5 nM, respectively). Formulations containing cyclopentolate have been used to induce pupil dilation and to prevent the eye from accommodating for near vision.

一般的な説明Cyclopentolatehydrochloride, 2-dimethylaminoethyl 1-hydroxy- -phenylcyclopentaneacetatehydrochloride (Cyclogyl), is a crystalline,white, odorless solid that is very soluble in water,easily soluble in alcohol, and only slightly soluble in ether.A 1% solution has a pH of 5.0 to 5.4.Cyclopentolate hydrochloride has one half of the antispasmodicactivity of atropine and is nonirritating when instilledrepeatedly into the eye. If not neutralized after the refractionstudies, its effect dissipates within 24 hours. Neutralizationwith a few drops of pilocarpine nitrate solution, 1% to 2%,often results in complete recovery in 6 hours. It is supplied asa ready-made ophthalmic solution in concentrations of either0.5% or 2%.
