Mechanism and action
Prometrium: La progestérone contenue dans Prometrium se lie aux récepteurs de la progestérone et module l'expression génique dans les tissus reproducteurs et d'autres tissus. Claritin: La loratadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets lors des réactions allergiques.
