Sildalist is a medication that combines two active ingredients, sildenafil and tadalafil, both of which are used to treat erectile dysfunction (ED) in men. Sildenafil is the active ingredient in Viagra, while tadalafil is the active ingredient in Cialis. The combination of sildenafil and tadalafil in Sildalist offers the benefits of both medications. Sildenafil works by increasing blood flow to the penis, which helps men achieve and maintain an erection, while tadalafil also works by increasing blood flow and has a longer duration of action compared to sildenafil.
