Amlodipine vs Sitagliptin: side-by-side comparison
Amlodipine (Dihydropyridine calcium-channel blocker) and Sitagliptin (DPP-4 inhibitor) belong to different therapeutic classes and are rarely substitutes for each other. The comparison is useful when a single patient is weighing both options for adjacent or overlapping needs.

What they share
Amlodipine and Sitagliptin share the common regulatory framework for prescription active ingredients, bioequivalence standards for generics, and pharmacist oversight. Beyond that, points in common are limited.
Key differences
Amlodipine acts by a different mechanism than Sitagliptin, 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
Amlodipine: L'amlodipine bloque sélectivement les canaux calciques de type L du muscle lisse vasculaire, réduisant l'entrée transmembranaire de calcium et produisant une vasodilatation artérielle périphérique. 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).
Indications compared
Amlodipine: L'amlodipine est autorisée chez l'adulte dans le traitement de l'hypertension artérielle essentielle et de l'angor stable chronique, ainsi que dans l'angor vasospastique (de Prinzmetal). 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.
Safety profile
Amlodipine: Les effets indésirables fréquents comprennent les œdèmes périphériques (typiquement des chevilles), les bouffées vasomotrices, les céphalées, les palpitations et la fatigue, le plus souvent dose-dépendants. Sitagliptin: La sitagliptine est généralement bien tolérée.
Questions fréquentes
Is Amlodipine better than Sitagliptin? ▾
Amlodipine and Sitagliptin are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Amlodipine and Sitagliptin 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.
