Fildena is a widely recognized medication used to treat erectile dysfunction (ED) in men. Its active ingredient, sildenafil citrate, belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Fildena enhances erection timing by improving blood flow to the penile tissues, making it easier for men to achieve and sustain a firm erection during sexual activity.

When a man is sexually aroused, nitric oxide is released in the penile region, which activates the enzyme guanylate cyclase. This enzyme increases the production of cyclic guanosine monophosphate (cGMP), a chemical that relaxes the smooth muscles and dilates blood vessels in the penis. These processes result in increased blood flow, essential for achieving an erection. However, in men with ED, the PDE5 enzyme breaks down cGMP too quickly, leading to difficulty in maintaining an erection.
