Which medication is commonly used to treat organophosphate poisoning?

Atropine is the medication commonly used to treat organophosphate poisoning because it acts as an antidote. Organophosphates are a group of chemicals that inhibit the activity of the enzyme acetylcholinesterase, leading to an accumulation of acetylcholine at synapses, causing overstimulation of cholinergic receptors. This can result in symptoms such as miosis, respiratory distress, and increased secretions.

Atropine is an anticholinergic agent that blocks the effects of acetylcholine at muscarinic receptors, which helps to reverse some of the severe symptoms caused by organophosphate poisoning, such as bronchoconstriction and excessive salivation. By reducing the activity of acetylcholine, atropine helps restore normal physiological function.

Other options do not serve the role of treating organophosphate toxicity. Albuterol is a bronchodilator primarily used in asthma and other respiratory conditions and does not address the underlying mechanism of organophosphate poisoning. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used for pain and inflammation, and it does not have any relevance in this form of poisoning. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used in the management of hypertension and
