Common Namealprostadil
DescriptionProstaglandin E1, also known as alprostadil or PGE1, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, prostaglandin E1 is considered to be an eicosanoid lipid molecule. Caverject and Edex are similarly fast-acting, but instead are injected by syringe directly into the corpus cavernosum of the penis. Prostaglandin E1 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. It works by opening blood vessels by relaxing smooth muscle. alprostadil is found in Larix sibirica and Populus balsamifera. alprostadil was first documented in 1997 (PMID: 9248778). This is primarily useful when the threat of premature closure of the ductus arteriosus exists in an infant with ductal-dependent congenital heart disease, including cyanotic lesions (e.G., Hypoplastic left heart syndrome, pulmonary atresia/stenosis, tricuspid atresia/stenosis, transposition of the great arteries) and acyanotic lesions (e.G., Coarctation of the aorta, critical aortic stenosis, and interrupted aortic arch) (PMID: 16701566) (PMID: 12445486) (PMID: 9612114) (PMID: 15086195).
