In ancient Chinese medicine it was used as a diaphoretic and antipyretic. Its action is similar to that of epinephrine. Its effects, although less powerful, are more prolonged, and it exerts action when given orally, whereas epinephrine is effective only by injection. Ephedrine dilates the bronchial muscles, contracts the nasal mucosa, and raises the blood pressure. It is used chiefly for its bronchodilating effect in asthma, and for its constricting effect on the nasal mucosa in hay fever.

 INCOMPATIBILITY: Calcium chloride, iodine, and tannic acid are incompatible with ephedrine.
