Sildenafil and Dapoxetine, two medications used to treat male erectile dysfunction and early ejaculation, are combined to form Super P Force. A phosphodiesterase type 5 (PDE 5) inhibitor called sildenafil increases blood flow to the penis during sexual stimulation and makes it possible for it to erect thereafter. A selective serotonin reuptake inhibitor (SSRI), dapoxetine prolongs the duration until ejaculation and enhances control of ejaculation by raising the level of serotonin in nerves.
