High Quality Prostaglandin E1 Powder for Impotence Treatments Alprostadil CAS: 745-65-3 Pge1

Alprostadil is the naturally occurring prostaglandin E1 (PGE1) which displays a variety of pharmacologic actions. Alprostadil is a potent vasodilator agent that increases peripheral blood flow, inhibits platelet aggregation, and induces bronchodilation. Used in the treatment of erectile dysfunction, this agent produces corporal smooth muscle relaxation by binding to PGE receptors, resulting in the activation of adenylate cyclase and the subsequent accumulation of 3'5'-cAMP.

Alprostadil injection and suppositories are used to treat certain types of erectile dysfunction (impotence; inability to get or keep an erection) in men. Alprostadil injection is also sometimes used in combination with other tests to diagnose erectile dysfunction. Alprostadil is in a class of medications called vasodilators. It works by relaxing the muscles and blood vessels in the penis to keep enough blood in the penis so that an erection can occur.

1.Patent ductus arteriosus: Alprostadil is also used in maintaining a patent ductus arteriosus in newborns . 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).

2.Sexual dysfunction: Alprostadil is sold in the United States as urethral suppositories and in injectable form. The suppositories are sold under the brand name Muse. The injectable forms are Edex and Caverject. Muse delivers alprostadil as a penile suppository, inserted into the urethra, at least ten minutes before the erection is needed. Caverject and Edex are similarly fast-acting, but instead are injected by syringe directly into the corpus cavernosum of the penis .

3.Critical limb ischemia: Prostanoids, including alprostadil, do not reduce the risk of limb amputation but may offer a slight improvement in rest-pain and leg ulcer healing in persons with critical limb ischemia.
