Mechanism and action
Allegra: La fexofénadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets sur la vasodilatation, la perméabilité capillaire, les terminaisons nerveuses sensitives et le muscle lisse. AndroGel: La testostérone contenue dans AndroGel traverse la peau, environ 10 % de la dose appliquée passant dans la circulation générale.
When Allegra is preferred
Allegra est autorisé chez l'adulte et l'enfant dans le traitement de la rhinite allergique saisonnière et de l'urticaire chronique idiopathique.
When AndroGel is preferred
