Pharmacotherapeutic group: Antispasmodics in combination with analgesics.
PHARMACOLOGY: Hyoscine Butylbromide exerts a spasmolytic action on the smooth muscle of the gastrointestinal, biliary and genitourinary tract. As a quaternary ammonium derivative, Hyoscine Butylbromide does not enter the central nervous system. Therefore, anticholinergic side effects at the central nervous system do not occur. Peripheral anticholinergic action results from a ganglion blocking action within the visceral wall as well as from an antimuscarinic activity.
Acetaminophen has analgesic and antipyretic actions, together with a very weak anti-inflammatory effect. Its mechanism of action is not fully understood. It strongly inhibits central prostaglandin synthesis but only weakly inhibits peripheral prostaglandin synthesis. It also inhibits the effect of endogenous pyrogens on the temperature regulation centre in the hypothalamus.
