Prostaglandin Analogs (Epoprostenol, Iloprost)

233

Summary

Prostacyclin analogs are a class of drugs containing the word stem -prost-, including epoprostenol and iloprost. These drugs act by mimicking the actions of prostacyclin, also known as prostaglandin I2, to induce arterial vasodilation. Clinically, prostacyclin analogs are most commonly used in the treatment of pulmonary hypertension. Side effects are rare but include flushing and jaw pain.
