Hyoscine is a drug that is also known by other names, such as scopolamine or hyoscine butyl bromide . It is used to treat pain and discomfort caused by abdominal and menstrual cramps or other spasmodic activities in the digestive system.
For decades it has been one of the drugs widely used to treat renal colic pain, alone or in association with metamizole.
It is important to bear in mind that it is not a drug to treat pain, such as drugs in the NSAID family, but that its effect is aimed at avoiding the cause of pain: the muscle spasm itself.
For this reason, this drug is categorized as an antispasmodic drug. Hyoscine is an alkaloid found in some plants of the genus Duboisia, such as Duboisia myoporoides .
Mechanism of action: how does hyoscine exert its effect in the body?
Hyoscine-derived salts, such as hyoscine butylbromide, are an anticholinergic drug with high affinity for muscarinic receptors found on smooth muscle cells of the digestive tract.
When this drug interacts with receptors, hyoscine triggers a spasmolytic effect. This drug also has the property of binding with nicotine receptors, thereby exerting a ganglionic blockade.
