🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionTheophylline is well absorbed from the gastrointestinal tract after oral administration. The immediate-release tablet is rapidly absorbed, but food may affect the rate of absorption. Bioavailability is high, generally around 96%.
DistributionTheophylline distributes widely throughout the body, including the lungs, heart, brain, and skeletal muscle. It crosses the placenta and is excreted in breast milk. The volume of distribution is approximately 0.5 L/kg.
Protein BindingApproximately 40% bound to plasma proteins, mainly albumin.
MetabolismTheophylline is metabolized in the liver by cytochrome P450 enzymes, primarily CYP1A2 and CYP3A4. Metabolism can be affected by liver disease, smoking, and other drugs.
Half-LifeThe elimination half-life varies widely: 3-5 hours in smokers, 8-10 hours in non-smokers, and longer in patients with liver disease or heart failure.
ExcretionTheophylline and its metabolites are excreted primarily in the urine. About 10% is excreted unchanged.
BioavailabilityApproximately 96% for oral immediate-release formulations.
Onset of ActionBronchodilation begins within 30 minutes to 1 hour after oral administration.
Peak Plasma Time1-2 hours for immediate-release tablets.
Duration of Action6-8 hours for immediate-release formulations.

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.

Mechanism Steps

1
Phosphodiesterase inhibition: Theophylline inhibits phosphodiesterase enzymes, preventing the breakdown of cyclic AMP.
2
Increased cyclic AMP: Elevated cyclic AMP levels cause relaxation of bronchial smooth muscle.
3
Adenosine receptor blockade: Theophylline blocks adenosine receptors, reducing bronchoconstriction and stimulating the central nervous system.
4
Bronchodilation: The combined effects lead to widened airways and easier breathing.
