Extra Super Tadarise is a medication used to treat erectile dysfunction (ED) and premature ejaculation (PE) in men. It contains two active ingredients: Tadalafil (20 mg) and Dapoxetine (60 mg). Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor that helps improve blood flow to the penis, resulting in an erection during sexual stimulation. Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) that helps delay ejaculation, thus treating premature ejaculation.
