What is pseudoephedrine-oral, and how does it work (mechanism of action)?
- Pseudoephedrine is a decongestant used for reducing nasal congestion caused by allergies or the common cold. Pseudoephedrine causes blood vessels in the nasal passages to shrink (vasoconstrict). Vasoconstriction reduces nasal congestion by preventing fluid from draining from blood vessels into nasal passages. Pseudoephedrine also directly stimulates beta-adrenergic receptors and causes relaxation of bronchioles, as well as increased heart rate and contractility.
- The FDA approved pseudoephedrine in August 1975.
