Alprostadil is a prostaglandin E1 analogue that can be administered as a urethral suppository to promote the dilation of the penile arteries and produce an erection. Sildenafil and vardenafil are oral medications that belong to the class of phosphodiesterase type 5 inhibitors and are usually taken about an hour before sexual activity. Papaverine is a smooth muscle relaxant that can be injected directly into the penis, but it is less commonly used due to the risk of prolonged erections and fibrosis of the penile tissue.
