Substance, pressor

A pressor substance is any substance that elevates arterial blood pressure. For example, prostacyclin (also known as prostaglandin PGI2) is a potent pressor agent. The word "pressor" comes from the French verb "presser" meaning "to exert pressure" or "to squeeze." In medicine, pressor refers to raising the blood pressure.
