Description

Butylscopolamine is a peripherally acting antimuscarinic, anticholinergic agent. It is used to treat pain and discomfort caused by abdominal cramps, menstrual cramps, or other spasmodic activity in the digestive system. It is also effective at preventing bladder spasms. It is not a pain medication in the normal sense, since it does not directly affect pain, but rather works to prevent painful cramps and spasms from occurring. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.

Pharmacology

Indication

Used to treat abdmoninal cramping and pain [Label].

Associated Therapies
Pharmacodynamics

Scopolamine butylbromide is a muscarinic antagonist which acts to prevent acetylcholine-stimulated contraction of smooth muscle in the gastrointestinal tract [1].

Mechanism of action

Scopolamine butylbromide binds to muscarinic M3 receptors in the gastrointestinal tract [1]. This prevents acetycholine from binding to and activating the receptors which would result in contraction of the smooth muscle. The inhibition of contraction reduces spasms and their related pain during abdominal cramping.

Absorption

Scopolamine butylbromide has extremely low oral bioavailability with only 0.25-0.82% reaching systemic circulation [1]. Peak plasma concentration is reached 0.25-2 hours. Scopolamine butylbromide does not cross the blood brain barrier.

Volume of distribution

The volume of distribution is 128 liters [1].

Protein binding
Not Available
Metabolism

Metabolism occurs mainly through hydrolysis of the ester bond [1]. The metabolites are not considered to be significantly active.

Route of elimination

Mainly eliminated in the feces (69.7%) with very little in the urine (4.4%) [1]. Only 2.8% is eliminated via the bile owing to scopolamine butylbromide's poor absorption.

Half life

The half life of elimination is 1-5 hours [1].

Clearance

Total clearace is 1.2 liters per minute [1].
