Theo-24 SR – Overview, Generic Name (Theophylline), and Benefits

Short General Description of Theo-24 SR

Theo-24 SR is a medication commonly prescribed to individuals with respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). This extended-release medication contains the active ingredient theophylline, which belongs to a class of drugs known as methylxanthines.

Methylxanthines are bronchodilators, which means they help to relax and widen the airways, making it easier for individuals to breathe. Theo-24 SR works by stimulating the muscles in the airways and decreasing inflammation, thereby improving airflow and reducing symptoms such as wheezing, shortness of breath, and coughing.

While theophylline may not be as well-known as some other medications for respiratory conditions, it has been used for decades and has proven to be highly effective for many patients.

Although Theo-24 SR is the most common name for this medication, it may also be sold under other brand names, including Uniphyl, Theobid, and Theo-Dur. These alternative names refer to the same medication with the same active ingredient, theophylline, but are simply marketed under different names by different pharmaceutical companies.

It’s important to note that the use of Theo-24 SR should be closely monitored by a healthcare professional. Proper dosage and regular monitoring of blood levels are essential to ensure the medication is both safe and effective.

This heightened drug concentration can potentially increase the risk of side effects. It is therefore crucial for healthcare professionals to closely monitor theophylline levels in older patients and adjust dosage accordingly.


Research has suggested that gender can also play a role in theophylline levels. Females tend to have lower clearance rates than males, resulting in higher drug concentrations. This discrepancy may be attributed to hormonal differences and variances in drug metabolism. Healthcare providers should consider this factor when prescribing Theo-24 SR to ensure proper dosage adjustments.

Smoking Habits

A particularly interesting finding is the effect of smoking on theophylline levels. Smoking has been found to accelerate the metabolism of theophylline, leading to lower drug concentrations. As a result, smokers may require higher doses of Theo-24 SR to achieve the desired therapeutic effect. It is crucial for healthcare professionals to inquire about smoking habits when determining appropriate dosage for patients.

Medical Conditions

Certain medical conditions can also influence theophylline levels. For example, individuals with liver disease may experience decreased drug clearance, resulting in higher concentrations. Conversely, patients with hyperthyroidism may have increased clearance rates, leading to lower levels of theophylline. It is essential for healthcare providers to carefully assess each patient’s medical history before prescribing Theo-24 SR and make necessary dosage adjustments.

Understanding the impact of these factors is invaluable in optimizing the use of Theo-24 SR and ensuring its effectiveness. By considering age, gender, smoking habits, and medical conditions, healthcare professionals can tailor the treatment plan to each patient’s specific needs.
