Résumé
Both are class I antiarrhythmics that depress cardiac conduction, so combined use can cause additive effects such as conduction delay, hypotension and proarrhythmia. Additive CNS toxicity, such as confusion or seizures, has also been described with both agents.
Ce que signifie cette interaction, en termes simples
Lidocaine and Procainamide 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.
Pourquoi elle survient
Additive sodium channel blockade slowing cardiac conduction, with overlapping CNS toxicity.
Conduite à tenir
Use together only with continuous ECG and blood pressure monitoring, and avoid unless clearly necessary. Reduce doses and watch for QRS widening, hypotension and neurologic symptoms.
