Man Loses Life After Quitting Smoking? #how. Source- Worcestershire Coroner Court PMID 32869278 Heavy cigarette smoking acts as a potent metabolic inducer, accelerating the rate at which the body clears clozapine. Polycyclic aromatic hydrocarbons found in tobacco smoke stimulate the liver's cytochrome P450 system, specifically boosting the activity of the CYP1A2 enzyme. This increased enzyme activity speeds up the breakdown of clozapine, which frequently requires heavy smokers to be prescribed higher doses of the medication to maintain therapeutic drug levels and manage their psychiatric symptoms effectively. When a patient suddenly stops or significantly reduces heavy smoking, this enzymatic induction rapidly fades, leading to dangerous clozapine accumulation. Without tobacco smoke to stimulate CYP1A2, the liver processes clozapine much more slowly, causing blood levels of the drug to spike dramatically even if the daily dosage remains unchanged. This unexpected surge in drug concentration can result in severe clozapine toxicity, increasing the risk of life-threatening side effects such as extreme sedation, seizures, severe hypotension, and cardiovascular complications. #medication #schizophrenia #pharma
