Indications
Belladonna Phenobarbitone tablets has the actions of Atropine which is a tertiary amine antimuscarinic alkaloid with both central and peripheral actions. It has antispasmodic actions on smooth muscles and reduces secretions, especially salivary and bronchial secretions; it also reduces perspiration. It reduces smooth-muscle tone and diminishes gastric and intestinal motility but has little effect on gastric secretions in usual therapeutic doses. Belladonna Phenobarbitone tablets have been used for their antimuscarinic actions in a wide range of conditions, including the relief of gastro-intestinal and urinary tract disorders associated with smooth muscle spasm.

Drug Interactions
The effect of Atropine activity may be enhanced by the concomittant administration of other drugs with antimuscarinic properties, such as amantadine, some antihistaminics, phenothiazine antipsychotics and tricyclic antidepressants. Inhibition of drug-metabolizing enzymes by MAOIs may possibly enhance the effects of antimuscarinics. The reduction in gastric motility caused by antimuscarinics may affect the absorption of other drugs.Antimuscarinics and parasympathomimetics may counteract each others effects. The effect of phenobarbitone is enhanced by the concurrent administration of other CNS depressants including alcohol. Phenobarbitone may reduce the activity of many drugs by increasing the rate of metabolism through induction of drug-metabolizing enzymes in liver microsomes.
