Mechanism and action
Ozempic: Après injection sous-cutanée, le sémaglutide est lentement absorbé et se lie au récepteur du GLP-1 des cellules bêta et alpha pancréatiques, du système nerveux central et de l'intestin. 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.
When Ozempic is preferred
