What does atropine block?

Atropine is a clinically relevant anticholinergic drug, which blocks inhibitory effects of the parasympathetic neurotransmitter acetylcholine on heart rate leading to tachycardia. However, many cardiac effects of atropine cannot be adequately explained solely by its antagonism at muscarinic receptors.

What does atropine do to the heart?

Atropine increases the heart rate and improves the atrioventricular conduction by blocking the parasympathetic influences on the heart.

Is atropine a poison?

Side effects In overdoses, atropine is poisonous. Atropine is sometimes added to potentially addictive drugs, particularly antidiarrhea opioid drugs such as diphenoxylate or difenoxin, wherein the secretion-reducing effects of the atropine can also aid the antidiarrhea effects.

How does atropine work?

Mechanism Of Action Atropine competitively blocks the effects of acetylcholine, including excess acetylcholine due to organophosphorus poisoning, at muscarinic cholinergic receptors on smooth muscle, cardiac muscle, secretory gland cells, and in peripheral autonomic ganglia and the central nervous system.

Does atropine cause hallucinations?

Visual hallucinations are a major side effect of anticholinergic poisoning. Ophthalmic instillation of atropine has been documented to cause many central nervous sytstem symptoms, including hallucinations.

What type of drug is atropine?

Atropine is commonly classified as an anticholinergic or antiparasympathetic (parasympatholytic) drug. More precisely, however, it is termed an antimuscarinic agent since it antagonizes the muscarine-like actions of acetylcholine and other choline esters.
