Prostaglandin E1 Alcohol is primarily used in medical treatments due to its vasodilatory and anti-inflammatory properties. It is commonly applied in the management of erectile dysfunction, where it helps to relax smooth muscle tissue and increase blood flow. Additionally, it is utilized in the treatment of peripheral vascular diseases to improve circulation in affected limbs. In neonatal care, it is administered to maintain the patency of the ductus arteriosus in newborns with congenital heart defects, ensuring adequate blood flow until corrective surgery can be performed. Its role in reducing platelet aggregation also makes it beneficial in preventing blood clots in certain clinical scenarios.
