Established name: scopolamine hydrobromide

Chemical name: benzeneacetic acid, α-(hydroxymethyl)-, 9-methyl-3-oxa-9-azatricyclo[,4]non-7-yl ester, hydrobromide, trihydrate, [7(S)-(1α,2β,4β,5α,7β)]-.

Clinical Pharmacology Section

This anticholinergic preparation blocks the responses of the sphincter muscle of the iris and the accommodative muscle of the ciliary body to cholinergic stimulation, producing pupillary dilation (mydriasis) and paralysis of accommodation (cycloplegia).

Indications & Usage Section

For mydriasis and cycloplegia in diagnostic procedures. For some pre- and postoperative states when a mydriatic and cycloplegic is needed in treatment of iridocyclitis.

Contraindications Section

Contraindicated in persons with primary glaucoma or a tendency toward glaucoma, e.g., narrow anterior chamber angle; and in those showing hypersensitivity to any component of this preparation.

Warnings Section

Do not touch dropper tip to any surface, as this may contaminate the solution.


Precautions Section

To avoid excessive absorption, the lacrimal sac should be compressed by digital pressure for two to three minutes after instillation. To avoid inducing angle closure glaucoma, an estimation of the depth of the angle of the anterior chamber should be made.

Patient Warning

Patient should be advised not to drive or engage in other hazardous activities when drowsy or while pupils are dilated. Patient may experience sensitivity to light and should protect eyes in bright illumination during dilation. Parents should be warned not to get this preparation in their child’s mouth and to wash their own hands and the child’s hands following administration.
