How Buscopan® works

Targeted and effective relief from abdominal pain and cramps
The active ingredient in Buscopan® is Hyoscine Butylbromide, a substance derived from a species of the plant genus Duboisia. Hyoscine Butylbromide is one of the families of drugs known as antispasmodics. As the name suggests, these drugs suppress and relieve spasms.
What makes Hyoscine Butylbromide so effective against the discomfort and pain of abdominal cramps is its extremely targeted effect. It doesn't simply mask the pain, like an analgesic. Instead, it acts on the cause of the pain: the muscle spasm itself. And unlike other antispasmodics, it does not cross the blood brain barrier and is unlikely to cause drowsiness. It acts only where it's needed, quickly and effectively, to relieve the discomfort and pain of abdominal cramps.
