Key differences
Neurontin belongs to Médicaments neurologiques while Vardenafil belongs to Dysfonction érectile. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Neurontin: La gabapentine se lie à la sous-unité auxiliaire alpha-2-delta des canaux calciques voltage-dépendants du système nerveux central, réduisant l'entrée présynaptique de calcium et la libération de neurotransmetteurs excita… Vardenafil: Le mécanisme est identique à celui du Levitra d'origine : le vardénafil inhibe sélectivement la PDE5 dans le muscle lisse pénien, ce qui permet au GMP cyclique produit lors de l'excitation sexuelle de s'accumuler.
When Neurontin is preferred
Neurontin est autorisé chez l'adulte et l'enfant à partir de 3 ans en traitement adjuvant des crises épileptiques partielles, et chez l'adulte dans la névralgie post-zostérienne.
When Vardenafil is preferred
Le vardénafil générique partage l'indication du princeps : la dysfonction érectile chez l'homme adulte.
