Bellacid is an antispasmodic and sedative compound that contains two
synergically active substances, belladonna and phenobarbitone.
Belladonna is a cholinergic depressant, it therefore inhibits excessive
motility of the viscera such as the stomach, intestines, colon, ureters, urinary
bladder and biliary passages. It also diminishes excessive gastric and other
secretions. Phenobarbitone is a central sedative, an action which is required
in such cases where spasm is coupled with anxiety. Moreover, the
barbiturates enhance the anticholinergic action of belladonna.
