This document summarizes information about two adrenergic drugs. Phenylephrine is used for temporary relief of stuffy nose, sinus, and ear symptoms caused by common colds, flu, allergies, or other breathing illnesses by decreasing swelling in the nose and ears. Salbutamol relaxes the smooth muscle in the lungs and opens airways to improve breathing and is used to treat asthma, chronic bronchitis, emphysema, and prevent exercise-related asthma. The document was written by Dr. P Parthiban, a professor at Vellalar College of Pharmacy.

other breathing illnesses (e.g., sinusitis, bronchitis). This medication
works by decreasing swelling in the nose and ears, thereby
lessening discomfort and making it easier to breathe.
