Norvasc belongs to Médicaments cardiovasculaires while Acyclovir belongs to Antiviraux. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Norvasc: L'amlodipine bloque sélectivement les canaux calciques de type L du muscle lisse vasculaire, réduisant l'entrée transmembranaire de calcium et produisant une vasodilatation artérielle périphérique. Acyclovir: L'aciclovir est un analogue de la guanosine phosphorylé sélectivement par la thymidine kinase virale en monophosphate, puis par les kinases cellulaires en aciclovir triphosphate.
When Norvasc is preferred
Norvasc est autorisé chez l'adulte dans le traitement de l'hypertension artérielle essentielle et de l'angor stable chronique, ainsi que dans l'angor vasospastique (de Prinzmetal).
When Acyclovir is preferred
L'aciclovir est autorisé chez l'adulte et l'enfant dans le traitement des infections à herpès simplex, dont l'herpès génital (épisodes initiaux et récurrents), le traitement suppressif de l'herpès génital récidivant, l'herpès labial, l'herpès cutanéo-muqueux chez l'immunodéprimé…
