Fildena 120 mg is a medication primarily used to treat erectile dysfunction (ED) in men. The active ingredient in Fildena is Sildenafil Citrate, the same active compound found in Viagra. Fildena 120 mg is a higher-dose formulation of this medication and is typically prescribed for men who require a stronger dose to achieve and maintain an erection. Sildenafil Citrate works by inhibiting the enzyme PDE5 (phosphodiesterase type 5), which normally restricts blood flow in the penis. https://www.genericday.com/fildena-120-mg.html
