🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Theophylline inhibits phosphodiesterase enzymes, increasing cyclic AMP levels, which leads to relaxation of bronchial smooth muscle. It also blocks adenosine receptors, contributing to bronchodilation and mild anti-inflammatory effects. Ambroxol increases serous bronchial secretion, reduces mucus viscosity, and stimulates surfactant production, enhancing mucociliary clearance.
