General
- AKA: aloprostadil
- Type: smooth muscle relaxer, vasodilator
- Dosage Forms: intravenous, penile injection, penile suppository
- Common Trade Names: Alprostadil, Prostin VR, Caverject, Muse, Edex
- Uses: maintenance of patent ductus arteriosus in neonates with duct-dependent congenital heart defects; treatment of erectile dysfunction in adults
Adult Dosing
Pediatric Dosing[1]
- Start infusion at 0.05 mcg/kg/min IV
- Titrate to 0.1 mcg/kg/min as tolerated, monitoring for hypotension (and apnea)
Special Populations
- Pregnancy Rating: C
- Lactation: infant risk cannot be ruled out
- Renal Dosing
- Adult
- Pediatric
- Hepatic Dosing
- Adult
- Pediatric
Contraindications
- Allergy to class/drug
Adverse Reactions
- Beware of three common side effects that may require further resuscitation[2][3]:
- Apnea (12%), which requires respiratory monitoring with ETCO2 capnography, potential mechanical ventilation, and/or ALS/PALS transport if needing transfer to higher level of care
- Peripheral flushing with or without hypotension (10%), which requires fluid resuscitation
- Fever (14%)
- Others:
Pharmacology
- Half-life: 5-10m
- Metabolism: Lung
- Excretion: Renal
- Mechanism of Action: synthetic of endogenous prostaglandin
Comments
- Cyanotic neonates with ductal-dependent lesions typically respond within 10-15 minutes, but may not show response until several hours after the start of infusion.
