What is prostaglandin E1 and its use?

Prostaglandin E1 (PGE1) is a medication used in the management of erectile dysfunction and ductus arteriosus in neonates. It is a smooth muscle relaxant and vasodilator.

How do you calculate prostaglandin?

Use one of the following methods to prepare a solution for infusion.

  1. Dilute one ampul in 500 ml D5W or D10W = 1 mcg/ml (0.001 mg/ml) solution. To give 0.05 mcg/kg/min. =
  2. [weight (kg) ÷ 10] = # mg PGE1 in 100 ml IVF @ 3 ml/hr = 0.05 mcg/kg/min.
  3. Dilute one vial in 100 ml of D5W or D10W = 5 mcg/ml solution.

Is alprostadil a hormone?

Alprostadil is a synthetic (man made) version of the hormone prostaglandin E1 (PGE1) which occurs naturally in your body. It helps treat the symptoms of erectile dysfunction because it is a ‘vasodilator’, which means that it widens blood vessels.

Is misoprostol PGE1 or PGE2?

Misoprostol is a newer synthetic PGE1, acts on myometrium. It can be given through oral, sublingual, intravaginal and rectal route. It is cheaper as compare to PGE2 (Dinoprostone gel) and requires no refrigeration. It has side effects like hyperstimulation, tachysystole of uterus.

What is the action of prostaglandin?

Which is the mechanism of action of alprostadil?

Alprostadil is a Prostaglandin Analog and Prostaglandin E1 Agonist. The mechanism of action of alprostadil is as a Prostaglandin Receptor Agonist. The physiologic effect of alprostadil is by means of Genitourinary Arterial Vasodilation and Venous Vasodilation. The chemical classification of alprostadil is Prostaglandins.

How is alprostadil used to treat erectile dysfunction?

Alprostadil is a medication used to treat erectile dysfunction. Alprostadil is produced endogenously and causes vasodilation by means of a direct effect on vascular and ductus arteriosus (DA) smooth muscle, preventing or reversing the functional closure of the DA that occurs shortly after birth.

How is alprostadil used in congenital heart disease?

In cyanotic congenital heart disease, alprostadil’s actions result in an increased oxygen supply to the tissues. In infants with interrupted aortic arch or very severe aortic coarctation, alprostadil maintains distal aortic perfusion by permitting blood flow through the DA from the pulmonary artery to the aorta.

What is the effect of prostaglandin E1 on smooth muscle?

Alprostadil ( prostaglandin E1) is produced endogenously to relax vascular smooth muscle and cause vasodilation. In adult males, the vasodilatory effects of alprostadil on the cavernosal arteries and the trabecular smooth muscle of the corpora cavernosa result in rapid arteriolar inflow and expansion of the lacunar spaces within the corpora.
