Bronchodilator and Antihistamine combination (Asthma relief)
Last reviewed May 2026
Who is this for?
This is a combination drug containing three active ingredients: ephedrine (which opens up the airways), theophylline (which relaxes the muscles around the airways to help you breathe easier), and chlorphenamine (an antihistamine that reduces allergic reactions like sneezing and runny nose). Together, they work to relieve breathing difficulties caused by asthma and allergies.
