Final answer:
Epoprostenol and nitric oxide are substances that have effects on blood vessels and circulation in the body. Epoprostenol dilates blood vessels and prevents blood clots, while nitric oxide causes vasodilation and lowers blood pressure.
Step-by-step explanation:
Epoprostenol and nitric oxide are both substances that have effects on blood vessels and circulation in the body.
Epoprostenol, also known as prostacyclin, is a synthetic form of prostaglandin. It works by dilating blood vessels and preventing the formation of blood clots. Some common side effects of epoprostenol include headache, flushing, jaw pain, and nausea.
Nitric oxide, on the other hand, acts as a gas and a ligand in the body. It diffuses directly across the plasma membrane and interacts with receptors in smooth muscle, causing relaxation of the tissue. Nitric oxide is known to cause vasodilation, which can lower blood pressure. Some common side effects of nitric oxide include dizziness, headaches, and increased heart rate.
