Résumé
Levodopa is converted to dopamine and noradrenaline, and a non-selective MAO inhibitor (phenelzine) prevents their breakdown so the amines accumulate. Entacapone further impairs catecholamine breakdown through COMT inhibition. Severe hypertension, flushing, headache and hyperpyrexia may follow.
Ce que signifie cette interaction, en termes simples
Carbidopa-entacapone-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-entacapone-levodopa belongs to Central Nervous System; Phenelzine belongs to Central Nervous System.
Pourquoi elle survient
Non-selective MAO inhibition prevents degradation of levodopa-derived catecholamines with additional COMT inhibition
Conduite à tenir
Do not give together. Wait at least 14 days after stopping phenelzine before starting the other drug; carbidopa reduces but does not eliminate the risk.
