🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works through two different ingredients. Phenylephrine is an alpha-1 adrenergic receptor agonist that causes blood vessels in the nasal mucosa to constrict, which reduces swelling and nasal stuffiness. Guaifenesin is an expectorant that increases the volume and reduces the viscosity of respiratory tract secretions, making mucus thinner and easier to clear by coughing. The combination addresses both nasal blockage and chest congestion.
