The definitive treatment for organophosphate poisoning is atropine, which competes with acetylcholine at the muscarinic receptors.
Why atropine is used in organophosphorus poisoning?
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.

What is the antidote of atropine?
The antidote to atropine is physostigmine or pilocarpine.
What is the example of mechanical antidote?
3) Mechanical Antidotes: Mechanical antidotes which prevent the absorption of poison into the body. For example, activated charcoal absorbs the poison prior to absorption across intestinal wall.

What are the complications of organophosphate (OP) toxicity?
Potential complications include: paralysis fertility issues cancer metabolic disorders, such as high blood sugar levels inflammation of the pancreas excess acid in the blood brain and nerve problems
What is the epidemiology of organophosphorus poisoning?
Epidemiology The incidence of organophosphate poisoning depends on the extent of use and ease of access. In the US and other developed countries, relatively few people are involved in agricultural activity, and occupational health and safety standards are usually enforced, making serious or fatal poisoning uncommon.
