Men with erectile dysfunction (ED) are the main patients for the medicine Fildena 50 mg. It contains 50 mg of Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor that improves blood flow to the penis, permitting an erection when sexually stimulated. 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. You can take Fildena with or without food, though meals heavy in fat may cause it to take longer to start working.
