GENERIC NAME: scopolamine
BRAND NAME: Transderm-Scop
DRUG CLASS AND MECHANISM: Scopolamine is an oral, intravenous, ophthalmic or topical drug with many uses including
the prevention of motion sickness. Transderm-Scop is scopolamine administered
topically (through the skin or transdermal) via a special delivery system that gradually releases scopolamine onto the skin over
a period of three days. The scopolamine is absorbed into the body through the skin. It is not clear how scopolamine prevents nausea
and vomiting due to motion sickness. The vestibular part of the ear is very important for balance. When a person becomes disoriented
due to motion, the vestibule sends a signal through nerves to the vomiting center in the brain, and vomiting occurs. Acetylcholine
is a chemical that nerves use to transmit messages to each other. Scientists believe that scopolamine prevents communication between
the nerves of the vestibule and the vomiting center in the brain by blocking the action of acetylcholine. Scopolamine also may work
directly on the vomiting center. Scopolamine must be taken before the onset of motion sickness to be effective.
