Treatment of erectile dysfunction (ED) in men, particularly when oral medications like PDE5 inhibitors are ineffective, not tolerated, or contraindicated due to health reasons.
Alprostadil, the active ingredient, is a prostaglandin E1 analog that relaxes smooth muscle tissue in the corpora cavernosa of the penis and dilates blood vessels, increasing arterial blood flow to produce an erection.
Must be administered via intracavernosal injection directly into the penis; proper injection technique training is essential to avoid complications such as priapism (prolonged erection), bleeding, or infection. Not for use in men who should not engage in sexual activity due to cardiovascular conditions. May cause penile pain, bruising, or fibrosis with repeated use.
