What are the uses of this medicine?

• Propylhexedrine (Benzedrex) used for the temporarily relief of nasal congestion due to a cold, hay fever, or other upper respiratory allergies (allergic rhinitis).

How does this medicine work?

• Propylhexedrine is a TAAR1 agonist, like amphetamine.
• Consequently, it reverses the transporters for dopamine, norepinephrine, and serotonin, leading to a release of monoamines from presynaptic vesicles into the synaptic cleft.
• The increased level of monoamines within the synapse results in increased activity at their respective receptors.
• Additionally, propylhexedrine appears to inhibit VMAT2, leading to a further increase in the aforementioned monoamines.
• The pharmacological actions of propylhexedrine are similar to that of structurally similar stimulant phenethylamines, such as amphetamine.
