Amlodipine vs Sildenafil Citrate: side-by-side comparison
Amlodipine (Dihydropyridine calcium-channel blocker) and Sildenafil Citrate (PDE5 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 Sildenafil Citrate 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 Sildenafil Citrate, 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. Sildenafil Citrate: Le citrate de sildénafil inhibe sélectivement la phosphodiestérase de type 5 (PDE5), l'enzyme qui dégrade le guanosine monophosphate cyclique dans le corps caverneux.
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). Sildenafil Citrate: Le citrate de sildénafil est autorisé chez l'homme adulte dans le traitement de la dysfonction érectile.
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. Sildenafil Citrate: Les effets indésirables fréquents rapportés dans les essais cliniques comprennent céphalées, bouffées vasomotrices du visage, congestion nasale, dyspepsie et troubles visuels transitoires.
Questions fréquentes
Is Amlodipine better than Sildenafil Citrate? ▾
Amlodipine and Sildenafil Citrate are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Amlodipine and Sildenafil Citrate 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.
