Corex DX Syrup Substitute

Corex DX Syrup is a combination of two drugs, namely: Chlorpheniramine and Dextromethorphan, primarily used to treat dry cough. Chlorpheniramine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. It helps to provide relief from symptoms of allergy such as sneezing, running nose, watery eyes, itching, swelling and congestion or stiffness. Dextromethorphan belongs to the class of cough suppressants that works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Thus, it decreases the need to cough.
