Men with erectile dysfunction can be treated with the drug Fildena 100 mg. Sildenafil Citrate, the active component, is a member of the phosphodiesterase type 5 inhibitors pharmacological class. The way that Fildena 100 mg's sildenafil citrate inhibits PDE5 is by letting cGMP build up and relaxing the smooth muscle in the penis's blood arteries, which increases blood flow to the area and promotes erections. Only when sexual arousal is present can Fildena 100 mg take effect, and its effects can linger for up to four hours after consumption. It's critical to take this medication as directed by a physician and to observe dose guidelines. Stop using this medication with large meals and drinks.
