Tadapox is a pharmaceutical combination medication primarily used in the treatment of two common male sexual health issues: erectile dysfunction (ED) and premature ejaculation (PE). It is composed of two active ingredients, tadalafil and dapoxetine, each serving a specific purpose in addressing these conditions.

1. Tadalafil: Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual stimulation. This improved blood flow helps men achieve and maintain erections, making it effective in treating erectile dysfunction.
2. Dapoxetine: Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) that helps in the management of premature ejaculation by delaying the ejaculation process, thus extending the time to ejaculation during sexual activity.
