Resumo
Chlorpropamide is the sulfonylurea most strongly associated with a disulfiram-like reaction with alcohol, producing flushing, headache, nausea and palpitations. Alcohol also increases the risk of prolonged hypoglycemia in patients on this long-acting drug.
O que esta interação significa em palavras simples
Chlorpropamide and Ethanol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Por que acontece
Inhibition of aldehyde dehydrogenase leads to acetaldehyde accumulation, while alcohol-induced suppression of gluconeogenesis adds to sulfonylurea hypoglycemia.
O que fazer
Counsel the patient to avoid alcohol completely; consider switching to a newer sulfonylurea or another class if abstinence is unlikely.
