The drug Fildena is mainly used to treat erectile dysfunction (ED), a common disorder marked by the inability to obtain or sustain an erection strong enough for fulfilling sexual activity. Nitric oxide, a substance that relaxes the smooth muscles of the penis during sexual stimulation, is enhanced by this medicine, which is a member of a class of pharmaceuticals called phosphodiesterase type 5 (PDE5) inhibitors. An erection is the outcome of this relaxation, which increases blood flow to the penis.
Sildenafil, a strong and specific PDE5 inhibitor, is the active component of Fildena 200. By blocking the PDE5 enzyme, sildenafil prolongs the effects of cyclic guanosine monophosphate (cGMP), a substance that causes the smooth muscles of the penis to relax. Men with ED can get and sustain an erection fit for intercourse with the use of this mode of action.
