Busconil ®Oral Drops
  • Hyoscyamine sulfate is a tertiary amine antimuscarinic alkaloid with both central and peripheral actions .It has antispasmodic actions on smooth muscle and reduces secretions, especially salivary and bronchial secretions. When given orally it specifically inhibits the action of acetylcholine on structures innervated by postganglionic cholinergic nerves and on smooth muscles that respond to acetylcholine but lack cholinergic innervations, therefore it inhibits the  gastrointestinal propulsive motility and controls the excessive pharyngeal, tracheal and bronchial secretions, but it has little effect on gastric secretion in usual therapeutic doses.

Each 1 ml syrup contains:

  • Hyoscyamine sulfate                    0.125 mg
