Fildena CT 50 mg is a medication used primarily to treat erectile dysfunction (ED). Sildenafil citrate inhibits PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). cGMP is important for the relaxation of smooth muscle and the dilation of blood vessels. The active ingredient in Fildena CT 50 mg is sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. It helps manage ED by enhancing blood flow to the penis. Discuss any underlying health conditions, especially heart problems, high or low blood pressure, or liver issues, with your healthcare provider. Since Fildena CT 50 mg is chewable, it should be chewed thoroughly before swallowing.
