Tadalafil, the active ingredient in Tadfil 20 mg, works by increasing blood flow to the penis during sexual stimulation, leading to improved and prolonged erections. It helps men achieve and maintain a satisfactory erection for sexual activity. Tadfil 20 mg has a relatively long duration of action, with effects lasting up to 36 hours. This extended duration of action allows for more flexibility in timing sexual activity, as men can take the medication well in advance.
