🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Theophylline works by inhibiting phosphodiesterase enzymes, which leads to increased levels of cyclic AMP in airway smooth muscle cells. This causes relaxation of the bronchial muscles and widening of the airways. It also blocks adenosine receptors, which contributes to bronchodilation and stimulates the respiratory center in the brain. Additionally, it improves diaphragm contractility and mucociliary clearance.
