概要
MAO inhibitors are listed as contraindicated with methyldopa in labeling because of the risk of hypertensive reactions and excitation, and tranylcypromine may also oppose the hypotensive effect. Methyldopa is metabolised to catecholamine-like compounds that can be potentiated when MAO is inhibited.
この相互作用をわかりやすく説明すると
Methyldopa and Tranylcypromine 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.
Methyldopa belongs to Cardiovascular; Tranylcypromine belongs to Central Nervous System.
なぜ起こるのか
MAO inhibition prevents breakdown of methyldopa-derived catecholamine metabolites, causing excess adrenergic stimulation.
対処法
Do not combine. Allow an adequate washout, about 14 days after stopping the MAOI, before starting methyldopa, and choose another antihypertensive.
