What is chlorpheniramine, pseudoephedrine, and how does it work (mechanism of action)?
Deconamine was a brand name medication that contains two different drugs, an antihistamine (chlorpheniramine) and a decongestant (pseudoephedrine). The antihistamine effects of chlorpheniramine account for its effect of reducing allergy symptoms. The decongestant action of pseudoephedrine is a result of blood vessel constriction in the nasal air passages, such as in the nose or sinuses. Brand name and generic formulations of combination products containing only chlorpheniramine and pseudoephedrine have been discontinued in the U. S., most likely due to the regulation of pseudoephedrine distribution.
