What does alprostadil mean?
Alprostadil is the generic name for a synthetic version of prostaglandin E1, a naturally occurring fatty-acid compound involved in smooth-muscle relaxation and blood-vessel widening. In medicine it serves two main purposes: it is administered directly into the penis — either by injection or as a urethral suppository — to induce erections in men with erectile dysfunction, particularly those who cannot take oral treatments such as sildenafil; and it is given intravenously to newborn infants whose survival depends on keeping the ductus arteriosus open until corrective heart surgery can be performed. Because it acts directly on blood vessels and smooth muscle, it must be dosed carefully under medical supervision. The name reflects its origin in prostaglandin research, itself named after the prostate gland. Alprostadil remains a well-established option in urology and neonatal cardiology worldwide.
nounA synthetic form of prostaglandin E1 used medically to treat erectile dysfunction and, in newborns, to keep the ductus arteriosus open in certain congenital heart defects.
- A pharmaceutical preparation of prostaglandin E1 used to treat erectile dysfunction by direct administration into the penis or via the urethra.
- A drug used in neonatal intensive care to maintain the patency of the ductus arteriosus in infants with certain congenital heart defects.
"The urologist explained that alprostadil injections could help patients who do not respond to oral medication."
"Alprostadil is administered intravenously to newborns awaiting surgery for duct-dependent cardiac lesions."
"For men who cannot take phosphodiesterase inhibitors, alprostadil offers an alternative delivered by penile self-injection."
Rarely pluralized; typically treated as a single medicinal substance, though different formulations may be described individually.
"Pharmacists compared several formulations of alprostadil on the shelf."
Alprostadil is essentially a lab-made copy of a fatty acid your body already makes — borrowed from the chemistry of the prostate gland and repurposed as medicine.

Etymology of alprostadil
Alprostadil was developed in the late twentieth century as a synthetic preparation of prostaglandin E1, a class of compounds first isolated from seminal fluid and named after the prostate gland. The 'prosta-' element of the name derives from that glandular association, while '-dil' is a standard pharmaceutical naming suffix. Its cognates include other members of the prostaglandin family, such as prostacyclin.
How alprostadil is actually used
Strictly a medical and pharmacological term; it appears in prescribing information, clinical literature, and patient-education materials rather than everyday conversation. It is a generic drug name available under various brand names in different countries.
Easily confused with alprostadil
Prostacyclin (prostaglandin I2) is a different prostaglandin used mainly as a vasodilator for pulmonary hypertension, whereas alprostadil is prostaglandin E1.
