Men with erectile dysfunction (ED) are the main patients for the medicine Fildena 50 mg. It has 50 mg of sildenafil citrate, an inhibitor of phosphodiesterase type 5 (PDE5) that increases blood flow to the penis and facilitates erections in response to sexual stimulation. Men can effectively acquire and sustain an erection during sexual activity with the use of Fildena 50. It functions by allowing for more blood flow by relaxing the blood vessels of the penis. 50 mg of Fildena should be taken orally 30 to 60 minutes before engaging in sexual activity. Individual efficacy and tolerability will determine whether to increase or decrease the dose to 25 mg or 100 mg.
