🔬 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. Pyridoxine is also readily absorbed from the gut.
DistributionTheophylline distributes widely throughout body fluids and tissues, including the lungs, liver, and central nervous system. It crosses the placenta and is excreted in breast milk. Pyridoxine is distributed to all tissues and is stored mainly in the liver.
Protein BindingTheophylline is approximately 40% bound to plasma proteins in adults. Pyridoxine binding is not clinically significant.
MetabolismTheophylline is metabolized primarily in the liver by cytochrome P450 enzymes, including CYP1A2 and CYP3A4. Pyridoxine is metabolized in the liver to pyridoxal phosphate and other metabolites.
Half-LifeThe elimination half-life of theophylline varies widely, typically ranging from 3 to 12 hours in healthy adults, but it can be longer in patients with liver disease, heart failure, or those taking interacting drugs. Pyridoxine has a short half-life of about 2 to 3 hours.
ExcretionTheophylline and its metabolites are excreted mainly in the urine. Pyridoxine metabolites are also excreted in urine.
BioavailabilityTheophylline is nearly completely bioavailable after oral administration, with a bioavailability of about 96% for immediate-release formulations. Pyridoxine is well absorbed.
Onset of ActionBronchodilation typically begins within 30 minutes to 1 hour after oral administration of immediate-release theophylline.
Peak Plasma TimePeak plasma concentrations of theophylline are usually reached within 1 to 2 hours after oral intake on an empty stomach, but may be delayed by food.
Duration of ActionThe bronchodilator effect of immediate-release theophylline generally lasts for 4 to 6 hours, but this can vary with the dose and individual metabolism.

How It Works

Theophylline works by inhibiting phosphodiesterase enzymes, which increases cyclic AMP levels in airway smooth muscle cells and leads to relaxation and bronchodilation. It also blocks adenosine receptors, which contributes to both bronchodilation and central nervous system stimulation. Additionally, theophylline may improve diaphragmatic contractility and mucociliary clearance. Pyridoxine is a water-soluble vitamin that is converted to pyridoxal phosphate, a coenzyme involved in many metabolic reactions, including the synthesis of neurotransmitters. It is added to this combination to help prevent or reduce theophylline-related neurological side effects such as peripheral neuropathy.

Mechanism Steps

1
Phosphodiesterase inhibition: Theophylline inhibits phosphodiesterase enzymes in airway smooth muscle, preventing the breakdown of cyclic AMP.
2
Increased cyclic AMP: Higher cyclic AMP levels cause relaxation of bronchial smooth muscle, leading to widened airways.
3
Adenosine receptor blockade: Theophylline blocks adenosine receptors, which reduces bronchoconstriction and may stimulate the central nervous system.
4
Improved diaphragmatic function: Theophylline enhances diaphragmatic contractility, which can help patients with respiratory muscle fatigue.
5
Pyridoxine coenzyme role: Pyridoxine is converted to pyridoxal phosphate, which acts as a coenzyme in neurotransmitter synthesis and may help prevent neurotoxicity from theophylline.

Dosage Information

Adult DosageThe usual adult dose of this medicine is one tablet taken orally once or twice daily, depending on the prescribed regimen. However, the exact dose and frequency must be individualized by a qualified clinician based on the patient's condition, response to therapy, and serum theophylline levels.

Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children.
Elderly DosageElderly patients may have reduced theophylline clearance and are more sensitive to its effects. Dose adjustment and close monitoring are recommended. Start with a lower dose and titrate slowly based on serum levels and clinical response.
Renal ImpairmentPatients with renal impairment may require dose adjustment. Monitor theophylline levels and renal function regularly. Consult your doctor for individualized dosing.
Hepatic ImpairmentPatients with hepatic impairment may have reduced theophylline metabolism and require lower doses. Close monitoring of serum levels is essential. Consult your doctor for individualized dosing.
Maximum Daily DoseThe maximum daily dose must be determined by a qualified clinician based on serum theophylline levels and clinical response. Do not exceed the prescribed dose.
