Super Fildena tablets contain a combination of medicines that are PDE5 inhibitor Sildenafil citrate and an SSRI drug called Dapoxetine. The working mechanism of Super Fildena is slightly complex as it works on the enzymatic level. This medication stops the breaking down of cyclic Guanosine Monophosphate (cGMP) vasodilator. Once the cGMP levels increases and helps to relax the smooth muscles and nitric oxide vasodilator increases the blood flow to the phallus. The higher blood flow to the phallus results in an erection when a man is sexually aroused. This drug offers four to five hours of effect.
