Atropine is an anticholinergic agent used primarily to treat bradycardia, a condition characterized by a slower-than-normal heart rate. It works by blocking the action of acetylcholine, a neurotransmitter that slows heart rate and can lead to decreased blood flow. Atropine also serves as a preoperative medication to reduce salivation and respiratory secretions. Additionally, it acts as an antidote for certain types of poisoning. In summary, Atropine is essential for managing bradycardia and facilitating surgical procedures.
Atropine blocks muscarinic acetylcholine receptors, leading to increased heart rate and reduced secretions by inhibiting parasympathetic nervous system activity.
