🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionGuaifenesin is absorbed from the gastrointestinal tract. Terbutaline is well absorbed orally, but bioavailability is reduced by first-pass metabolism.
DistributionGuaifenesin distribution is not well established. Terbutaline distributes widely, with some protein binding.
Protein BindingTerbutaline is approximately 25% bound to plasma proteins. Guaifenesin protein binding is not established.
MetabolismGuaifenesin undergoes hepatic metabolism. Terbutaline is metabolized in the liver, primarily by conjugation.
Half-LifeTerbutaline elimination half-life is approximately 3 to 4 hours. Guaifenesin half-life is approximately 1 hour.
ExcretionBoth drugs and their metabolites are excreted mainly in urine.
BioavailabilityTerbutaline oral bioavailability is about 15% due to first-pass metabolism. Guaifenesin bioavailability is not well established.
Onset of ActionTerbutaline onset of action is within 30 minutes after oral administration. Guaifenesin onset is not well established.
Peak Plasma TimeTerbutaline peak plasma levels occur in about 2 to 4 hours. Guaifenesin peak is not well established.
Duration of ActionTerbutaline duration of action is about 4 to 6 hours. Guaifenesin duration is not well established.

How It Works

This medicine combines two active ingredients with different mechanisms. Guaifenesin is an expectorant that works by increasing the volume and reducing the viscosity of secretions in the respiratory tract, which helps in the removal of mucus. Terbutaline is a selective beta-2 adrenergic agonist that stimulates beta-2 receptors in the bronchial smooth muscle, leading to relaxation and bronchodilation. This helps to relieve bronchospasm and improve airflow.

Mechanism Steps

1
Guaifenesin action: Guaifenesin increases respiratory tract fluid, reducing mucus viscosity and making cough more productive.
2
Terbutaline action: Terbutaline binds to beta-2 receptors on bronchial smooth muscle, causing relaxation and bronchodilation.
3
Combined effect: The combination facilitates mucus clearance and improves airflow, providing symptomatic relief in cough and bronchospasm.
