Men with erectile dysfunction can be treated with the drug
fildena 100mg. Sildenafil Citrate, the active component, is a member of the phosphodiesterase type 5 inhibitors pharmacological class. Nitric oxide, which is released by the body in response to sexual stimulation, relaxes the muscles in the penile blood vessels, increasing blood flow and resulting in an erection. But in men with ED, PDE5 breaks down cGMP, a molecule required for an erection, and NO levels are low. The effects of fildena 100mg might last for up to four hours after consumption and are only effective when sexual stimulation is present.
