Tadalafil helps a man achieve and maintain an erection by boosting blood flow to the penis when combined with sexual stimulation. Male sexual function issues, such as impotence or erectile dysfunction (ED), are treated with tadalafil.
Vardenafil is used to treat men with erectile dysfunction, commonly referred to as impotence—the inability to get or keep an erection. Vardenafil is a medication that is categorized as a phosphodiesterase (PDE) inhibitor. Blood flow to the penis is increased during sexual stimulation. An erection is the outcome of the increased blood flow.
Dapoxetine is a member of the class of medications known as selective serotonin reuptake inhibitors, which are mainly prescribed to adult men between the ages of 18 and 64 to treat premature ejaculation.
