Mechanism and action
Lantus: L'insuline glargine se lie au récepteur de l'insuline avec une affinité proche de celle de l'insuline humaine, activant une signalisation intracellulaire qui augmente la captation du glucose par le muscle et le tissu adi… Claritin: La loratadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets lors des réactions allergiques.
When Lantus is preferred
Le médicament est indiqué chez l'adulte et l'enfant atteints de diabète de type 1, et chez l'adulte atteint de diabète de type 2 lorsqu'une insuline basale est nécessaire.
When Claritin is preferred
Claritin est autorisé chez l'adulte et l'enfant dans le traitement de la rhinite allergique saisonnière et perannuelle et de l'urticaire chronique idiopathique.
