Muscarinic effects: • Bradycardia and hypotension. This poison, potentially present in cas- eating the food. Treatment of seizure disorders. • Chlorpyrifos, parathion, diazinon, famphur, phorate, terbufos, and malathion are examples of organophosphates while • Carbofuran, aldicarb, and carbaryl, are carbamates. Fortunately, he was immediately taken to hospital in a state of unconsciousness and kept in a mechanical ventilator. Methanol poisoning is actually rare, but when it occurs, many people are often involved simultaneously, hence the special place of methanol poisonings in clinical toxicology. muscle weakness. Long-term exposure to low levels of organophosphate pesticides (OP) may produce neuropsychiatric symptoms.

Atropine is a muscarinic receptor blocker, which acts to block the . Organophosphate (OP) compounds are a diverse group of chemicals used in both domestic and industrial settings. Poisoning with carbamates produces overstimulation of muscarinic and nicotinic receptors, resulting in specific clinical presentations. The focus of this article is poisoning from organophosphates, cyanide, ethylene glycol and methanol, laundry and cleaning products, mushrooms and plants, and carbon dioxide. Acute or chronic exposure to organophosphates can produce varying toxicity levels in humans, animals, plants, and insects. The longer the exposure and the larger the dose, the more toxic the effects.
