概要
Valganciclovir is the oral prodrug of ganciclovir, so the two are the same active substance and combining them duplicates therapy. This raises exposure and the risk of hematologic and other dose-related toxicity.
この相互作用をわかりやすく説明すると
Ganciclovir and Valganciclovir can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Ganciclovir belongs to Anti Virals; Valganciclovir belongs to Anti Virals.
なぜ起こるのか
