Ce que signifie cette interaction, en termes simples

Dipyridamole and Vorapaxar 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.

Pourquoi elle survient
