Erectile dysfunction, often known as the inability to obtain or sustain a firm and long-lasting erection sufficient for sexual activity, is the major condition for which Fildena is typically recommended. Men with erectile dysfunction (ED) can be treated with the drug brand Fildena. Its main component, sildenafil citrate, is present. Given that both Fildena and the more well-known brand of Viagra have sildenafil citrate as their active component, they both perform similarly. The same fundamental ED problem is treated by both drugs. There are several different strengths of Fildena, including Fildena 50 mg and Fildena 100 mg.
