Fliban 100 mg contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that helps men with ED achieve and maintain an erection. Sildenafil works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual stimulation. This improved circulation results in a firmer and longer-lasting erection. The typical dose is taken about 30 to 60 minutes before sexual activity. The effects usually last for 4 to 6 hours, allowing sufficient time for intimacy.
