Iloprost works by dilating the blood vessels. As an analog of prostacyclin, it mimics its effect. The exact mechanism has not yet been clarified, but it is assumed that iloprost inhibits the catecholamine outflow from nerve endings. It increases capillary density, which leads to reduced permeability. The active ingredient also has anti-inflammatory properties.
Iloprost is metabolized in the liver and excreted via the kidneys. The half-life of iloprost, i.e. the time it takes the body to excrete half of the active substance, is around 20-30 minutes.
Always take Iloprost exactly as described in the package leaflet or as advised by your doctor.

Prostaglandins owe their name to their discoverers, Goldblatt and Ulf, who first described prostaglandins as components of sperm in 1933. They assumed that the vasculogenic properties originated from the prostate. This assertion later turned out to be wrong. Prostaglandins were first isolated in 1962 by Sune Bergström and Bengt Samuelsson.
