概要
Methylene blue inhibits MAO-A, and combining it with serotonergic drugs such as nortriptyline can cause serotonin syndrome, which may be severe. The FDA has issued a warning on this interaction.
この相互作用をわかりやすく説明すると
Methylene blue and Nortriptyline 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.
なぜ起こるのか
MAO-A inhibition by methylene blue added to serotonin reuptake inhibition by nortriptyline.
対処法
Avoid the combination in non-emergency settings. If methylene blue is urgent, stop the serotonergic drug and monitor for CNS toxicity for up to two weeks or 24 hours after the last methylene blue dose, whichever comes first.
