Resumo
Levodopa is converted to dopamine and noradrenaline, and a non-selective MAO inhibitor (phenelzine) prevents their breakdown so the amines accumulate. Severe hypertension, flushing, headache and hyperpyrexia may follow.
O que esta interação significa em palavras simples
Carbidopa-levodopa and Phenelzine are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Carbidopa-levodopa belongs to Central Nervous System; Phenelzine belongs to Central Nervous System.
Por que acontece
Non-selective MAO inhibition prevents degradation of levodopa-derived catecholamines
O que fazer
