🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionSalbutamol is rapidly absorbed from the gastrointestinal tract after oral administration. Etofylline is also absorbed orally. However, oral bioavailability may be reduced due to first-pass metabolism.
DistributionBoth salbutamol and etofylline are distributed widely throughout the body, including the lungs. Salbutamol crosses the placenta and is excreted in breast milk. Protein binding information for etofylline is not well established.
Protein BindingSalbutamol is approximately 10% bound to plasma proteins. Protein binding of etofylline is not established from the available information.
MetabolismSalbutamol is metabolized in the liver primarily by conjugation to inactive sulfate esters. Etofylline is metabolized in the liver by oxidation and demethylation.
Half-LifeThe elimination half-life of salbutamol is approximately 4-6 hours. The half-life of etofylline is not well established but is estimated to be around 3-6 hours.
ExcretionSalbutamol and its metabolites are excreted mainly in the urine. Etofylline is also excreted in the urine, partly unchanged.
BioavailabilityOral bioavailability of salbutamol is approximately 40% due to first-pass metabolism. Bioavailability of etofylline is not well established.
Onset of ActionBronchodilation typically begins within 15-30 minutes after oral administration.
Peak Plasma TimePeak plasma concentrations of salbutamol are reached within 2-4 hours after oral administration. Peak levels of etofylline are not well established.
Duration of ActionThe bronchodilator effect usually lasts for 4-6 hours, but may vary.

How It Works

This medicine combines two bronchodilators with different mechanisms. Salbutamol selectively stimulates beta-2 adrenergic receptors in the airways, leading to relaxation of bronchial smooth muscle and rapid bronchodilation. Etofylline, a xanthine derivative, inhibits phosphodiesterase enzymes, increasing cyclic AMP levels and causing smooth muscle relaxation. Together, they work to open the airways and improve airflow.

Mechanism Steps

1
Beta-2 receptor stimulation: Salbutamol binds to beta-2 adrenergic receptors on bronchial smooth muscle cells, activating adenylate cyclase and increasing cyclic AMP.
2
Smooth muscle relaxation: Increased cyclic AMP leads to relaxation of bronchial smooth muscle, resulting in bronchodilation.
3
Phosphodiesterase inhibition: Etofylline inhibits phosphodiesterase enzymes, preventing the breakdown of cyclic AMP and further promoting smooth muscle relaxation.
4
Combined bronchodilation: The additive effects of both agents lead to enhanced airway opening and improved breathing.
