Sitagliptin acts by a different mechanism than Montelukast, with indications that barely overlap. Comparing the two is useful when a clinician has mentioned both in the same context or the patient wants to understand why one was prescribed instead of the other.
Mechanisms compared
Sitagliptin: La sitagliptine inhibe de façon réversible la DPP-4, sérine protéase responsable de la dégradation rapide du glucagon-like peptide 1 (GLP-1) et du polypeptide insulinotrope glucose-dépendant (GIP). Montelukast: Le montélukast bloque sélectivement le récepteur CysLT1, qui médie l'action des leucotriènes C4, D4 et E4 — médiateurs pro-inflammatoires libérés par les mastocytes et les éosinophiles au niveau des voies aériennes.

Sitagliptin: La sitagliptine est autorisée chez l'adulte atteint de diabète de type 2, seule ou en association à d'autres antidiabétiques, pour améliorer le contrôle glycémique. Montelukast: Le montélukast est autorisé chez l'adulte et l'enfant dans le traitement de fond de l'asthme, y compris le bronchospasme d'effort, et dans le traitement de la rhinite allergique saisonnière et perannuelle lorsque les tra…

Questions fréquentes
Is Sitagliptin better than Montelukast? ▾
Sitagliptin and Montelukast are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Sitagliptin and Montelukast be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.
Do they have the same side-effect profile? ▾
No — they belong to different classes and have distinct side-effect profiles. Each has its own prescribing information.
