Tadapox is a medication that combines two active ingredients, Tadalafil and Dapoxetine, to address two aspects of sexual health. It is used to treat erectile dysfunction (ED) and premature ejaculation (PE) in men. Tadalafil: Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, which helps increase blood flow to the penis during sexual stimulation, aiding in achieving and maintaining an erection. Dapoxetine: Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) that is used to delay ejaculation and improve control over ejaculation.
