Mechanism and action
Celebrex: Le célécoxib inhibe sélectivement la COX-2, isoforme inductible de la cyclo-oxygénase surexprimée sur les sites d'inflammation, tout en épargnant la COX-1 constitutive qui maintient l'intégrité de la muqueuse gastrique e… Plan B: Le mécanisme principal de Plan B est le retard ou le blocage de l'ovulation lorsqu'il est pris avant le pic de LH.
