Scopolamine 

Overview

Scopolamine (also known as hyoscine) is an anticholinergic medication used in clinical practice to prevent motion sickness and postoperative nausea and vomiting. It is typically supplied in regulated, approved dosage forms (such as transdermal patches or injectable preparations) and should be used only under medical guidance.

Medical Classification
