• Description: (-)Phenylephrine is a medication that belongs to the group of drugs called sympathomimetics. This drug is a potent vasoconstrictor that causes blood vessels to narrow and increases blood pressure. (-)Phenylephrine is used in humans as a pharmaceutical dosage for treatment of chronic bronchitis, hay fever, and other allergic reactions. It also has been shown to inhibit guanylate cyclase activity and can be used for the treatment of asthma. (-)Phenylephrine inhibits the action of two enzymes: cyclase and phosphodiesterase. This inhibition leads to an increased level of cAMP, which binds with G protein-coupled receptors in tissues that are rich in smooth muscle cells such as the airways or urinary bladder. The binding of cAMP with these receptors causes an increase in intracellular calcium ion levels, leading to relaxation of smooth muscles and improved breathing or urination.
