<p>Propantheline Bromide acts by dual mechanism of action.</p>

<ul>
	<li>Specific anticholinergic effect (antimuscarinic) at the acetylcholine-receptor sites</li>
	<li>Direct effect upon smooth muscle (musculotropic).</li>
</ul>

<p>This medication is a muscarinic antagonist having antispasmodic properties. It reduces the effect of acetylcholine, a chemical released from nerves that stimulates muscles, by blocking the receptors for acetylcholine on smooth muscle. It also has a direct relaxing effect on smooth muscle. In addition, Propantheline inhibits gastrointestinal motility and decreases gastric acid secretion and controls excessive pharyngeal, tracheal and bronchial secretions. Other secretions like pancreatic juice, sweat and saliva are also reduced.</p>
