The active ingredient in Fildena 100 mg is sildenafil citrate. Like other PDE5 inhibitors, sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5, which regulates blood flow in the pill. By inhibiting PDE5, sildenafil citrate increases blood flow to the pill during physical stimulation, facilitating the achievement and maintenance of an erection. Fildena 100 mg contains a standard dosage of sildenafil citrate. It is suitable for many individuals with ED and provides a balance between efficacy and potential side effects. https://www.onemedz.com/product/fildena-100-mg/
