Atropine
Mechanism of action |
Mechanism of action:
Cholenergic antagonist that selectively blocks all muscarinic responses to acetylcholine. Blocks parasympathetic vagal tone, decreasing Impulses to the heart. This increases the SA node firing rate, and increases conduction through the AV node. Also suppresses cholenergic overdose muscarinic responses caused by organophosphate and some chemical weapons. Is a potent bronchodilator when bronchoconstrition has been induced by parasympathomimetics. |
