T44.1

Clinical Causes: Accidental overdose of parasympathomimetic medications Intentional poisoning or self-harm attempts Underdosing due to incorrect medication administration Drug interactions that increase cholinergic activity Prolonged or excessive use of cholinergic drugs

Key Symptoms: Increased salivation and drooling Muscle weakness or twitching Difficulty breathing or breathing difficulties Abdominal cramps and diarrhea Nausea and vomiting Blurred vision or tunnel vision Confusion or altered mental state Bradycardia (slow heart rate) Fasciculations or involuntary muscle movements Seizures in severe cases

Diagnosis Path: Diagnosis of poisoning or adverse effects related to parasympathomimetics is primarily clinical, based on a detailed medical history and physical examination. Laboratory tests, including blood and urine analyses, may be conducted to detect the presence of the medication or its metabolites. Electromyography (EMG) and other neurological assessments can help evaluate neuromuscular involvement. In certain situations, measuring serum cholinesterase levels can aid in confirming cholinergic toxicity.

Treatment Protocols: Management of poisoning or adverse effects caused by parasympathomimetics involves several supportive strategies: - Immediate discontinuation of the offending medication - Administration of antidotes such as atropine, which counteracts muscarinic effects - Providing supportive care, including oxygen therapy and intravenous fluids - Monitoring vital signs and neurological status closely - Using benzodiazepines in cases of seizures - In severe cases, performing gastric lavage or activated charcoal to limit drug absorption - Ensuring proper respiratory support if breathing difficulties occur - Long-term care and rehabilitation for neurological or muscular sequelae, as needed Effective treatment depends on the severity of symptoms and prompt medical intervention. Prevention through correct medication use and adherence to dosing guidelines is crucial to avoid such toxicities.
