Propylhexedrine is a propylamine derivative with sympathomimetic property. Propylhexedrine binds to and activates alpha-adrenergic receptors in the mucosa of the respiratory tract, thereby mimicking the actions of norepinephrine and epinephrine. This results in vasoconstriction and reduces swelling and inflammation of the mucous membrane lining, therefore relieving nasal and sinus congestion.

4 Drug and Medication Information
4.1 Drug Indication

It is used to provide temporary symptomatic relief of nasal congestion due to colds, allergies and allergic rhinitis.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Like other monoamine releasing stimulants propylhexedrine is active as a norepinephrine and dopamine releaser in the central nervous system. The acute effects of the drug closely resemble the physiological and psychological effects of an epinephrine-provoked fight-or-flight response, including increased heart rate and blood pressure, vasoconstriction (constriction of the arterial walls), bronchodilation, and hyperglycemia (increased blood sugar).


5.2 Mechanism of Action

Propylhexidrine causes the norepinephrine, dopamine, and serotonin (5HT) transporters to reverse their direction of flow. This inversion leads to a release of these transmitters from the vesicles to the cytoplasm and from the cytoplasm to the synapse. It also antagonizes the action of VMAT2, causing the release of more neurotransmitters.
