Poxet containing the active ingredient dapoxetine is considered a type of selective serotonin reuptake inhibitor drug. The medication works by increasing serotonin activity in the nervous system and delaying the nerve messages that lead to ejaculation. The tablets can be used to increase the time required for ejaculation and improve ejaculation control. They are used in the treatment of premature ejaculation (PE) in men aged 18 to 64.
