Sildalist is a medication used to treat erectile dysfunction (ED) in men. It is a combination drug containing two active ingredients: sildenafil citrate and tadalafil. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, while tadalafil is also a PDE5 inhibitor but with a longer duration of action compared to sildenafil. Sildenafil Citrate: It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By blocking PDE5, sildenafil helps to increase blood flow to the penis, leading to improved erectile function. https://www.flatmeds.com/product/sildalist/
