The active ingredients of Super Kamagra 160 mg are sildenafil citrate and dapoxetine. Sildenafil belongs to the PDE-5 family of vasodilators taking care of erectile dysfunction. These drugs work by dilating the blood vessels in the body, particularly around the genital area. This, in turn, allows more robust blood flow to enable an erection to take place. Dapoxetine belongs to the family of (SSRI) serotonin reuptake inhibitors. It is the only drug with regulatory approval in many countries for the treatment of premature ejaculation.
