Alprostadil uses?

What is alprostadil used for?

Alprostadil is a synthetic form of prostaglandin E1. It’s used to help widen blood vessels and (depending on the condition and form) improve blood flow or trigger erections.

What conditions is it prescribed for?

Common uses depend on the form of alprostadil:

- Erectile dysfunction (male sexual health), typically when delivered as an intracavernosal injection or as a urethral suppository.
- Severe erectile dysfunction when other treatments are not suitable or have not worked.
- Certain congenital heart conditions in newborns to help keep the ductus arteriosus open and maintain blood flow until surgery or further treatment, where hospital-based dosing is used.

How does it work in the body?

Alprostadil acts on blood vessel and smooth muscle signaling (via prostaglandin pathways), which can:
- Increase blood flow by relaxing vascular smooth muscle.
- Support erection in erectile dysfunction by improving penile blood flow and reducing constriction.

What form should I look for when asking “alprostadil uses”?

If you mean one specific product, “uses” can change based on delivery method:
- Injection into the penis
- Urethral suppository
- Intravenous use for neonatal congenital heart disease (hospital use)

If you tell me which alprostadil product or route you mean (injection, urethral suppository, or IV), I can narrow the uses to that specific form.
