Gourt Home::Gourt :: Topical decongestant
Topical decongestants are decongestants applied directly to the nasal cavity. By applying them directly to the site of action, topical decongestants relieve nasal congestion while reducing the side effects associated with systemically-acting decongestants, such as high blood pressure.
Mechanism of action
Topical decongestants are vasoconstrictors, and work by constricting the blood vessels within the nasal cavity.
