Resumo

Linezolid is a reversible non-selective MAO inhibitor. Bupropion is contraindicated with MAO inhibitors because of the risk of hypertensive reactions, and linezolid may also raise the risk of serotonin toxicity or neurotoxicity. The combination can cause severe adverse reactions.

O que esta interação significa em palavras simples
