Pharmacokinetics of Theo-24 Cr

Theo-24 Cr is a widely prescribed medication for the management of asthma. Understanding its pharmacokinetics is crucial for optimizing its therapeutic effects and ensuring patient safety.


Theo-24 Cr is available in extended-release capsules, designed to release the medication slowly and steadily over a 24-hour period. The active ingredient, theophylline, is well-absorbed in the gastrointestinal tract, with peak plasma levels occurring approximately 4 to 5 hours after administration. Absorption can be affected by food intake, as high-fat meals can decrease the rate of absorption. Therefore, it is recommended to take Theo-24 Cr on an empty stomach to achieve optimal absorption.


Once absorbed into the bloodstream, theophylline is extensively distributed throughout the body, including the lungs. It readily crosses the blood-brain barrier and placenta, and it is also found in breast milk. Binding to plasma proteins is moderate, with approximately 50-60% of theophylline bound to albumin. The volume of distribution varies depending on factors such as age, body weight, and medical conditions.


Theophylline undergoes hepatic metabolism primarily by cytochrome P450 enzymes, specifically CYP1A2. Genetic variations in these enzymes can influence the metabolism of theophylline, leading to interindividual variability in drug response and potential drug interactions. Smoking and certain medications, such as cimetidine and erythromycin, can inhibit the metabolism of theophylline, resulting in increased blood levels.

“According to the FDA, theophylline has a narrow therapeutic index, meaning that there is a small margin between the therapeutic dose and toxic levels.”


Theophylline is primarily excreted in the urine. Its elimination half-life can vary widely among individuals, ranging from 3 to 9 hours in healthy individuals and up to 40 hours in patients with impaired liver function. Renal dysfunction can significantly affect the elimination of theophylline, necessitating dosage adjustments to prevent drug accumulation and toxicity.

Monitoring of blood levels is often recommended to ensure theophylline remains within the therapeutic range. Toxic levels can result in adverse effects such as nausea, vomiting, arrhythmias, and seizures.

Understanding the pharmacokinetics of Theo-24 Cr is crucial for healthcare professionals to effectively prescribe and monitor its use in asthma management. It is important to consider individual patient factors and potential drug interactions to optimize the benefits of this medication in respiratory disease control.
