Theophylline 50 mg Slow Release (MEM4) Oral Capsules are a specialized formulation designed to manage symptoms associated with respiratory diseases such as asthma, chronic bronchitis, and emphysema. Theophylline, the active ingredient, is a bronchodilator that works by relaxing the muscles in the lungs and chest, making it easier to breathe. By incorporating Methocel E4M, a hydrophilic methylcellulose ether polymer, these capsules ensure a controlled and sustained release of theophylline into the bloodstream. This slow-release mechanism allows for a consistent therapeutic level of the drug to be maintained over an extended period, typically resulting in a reduction of dosing frequency to once or twice daily, depending on the individual patient's response and the severity of symptoms.

The use of Methocel E4M in the formulation of these capsules is critical for achieving the desired pharmacokinetic profile. It forms a gel matrix when it comes into contact with gastric fluids, which then controls the rate at which theophylline is released. This not only minimizes the risk of fluctuating blood levels and potential side effects but also improves patient adherence to the medication regimen by simplifying the dosing schedule. For patients with chronic respiratory conditions, maintaining steady therapeutic levels of medication can significantly improve quality of life by reducing the frequency and severity of symptoms such as shortness of breath, wheezing, and coughing.

It is important for prescribers to consider the individual needs of their patients when choosing a theophylline formulation. Factors such as concurrent medications, comorbidities, and lifestyle can influence the effectiveness and tolerability of theophylline therapy. Regular monitoring of serum theophylline levels may be necessary to ensure optimal dosing and to avoid potential toxicity. Patients should be advised to take these capsules whole, without crushing or chewing them, to maintain the integrity of the slow-release system.

Theophylline is a bronchodilator used to treat symptoms of asthma, chronic bronchitis, emphysema, and other lung diseases. It works by relaxing muscles in the lungs and chest, making it easier to breathe. Theophylline 50 mg Slow Release (MEM4) Oral Capsules are designed to maintain steady therapeutic levels of the drug in the bloodstream, which is particularly important for managing chronic respiratory conditions. However, theophylline has a narrow therapeutic index, meaning that the range between an effective dose and a toxic dose is small. Therefore, it is crucial to be aware of potential drug interactions that could affect theophylline levels in the body.

Several classes of drugs can interact with theophylline, either by affecting its metabolism or by having additive effects on the cardiovascular or nervous systems. Drugs that can increase theophylline levels include cimetidine, erythromycin, fluoroquinolone antibiotics (like ciprofloxacin), certain antiarrhythmics (such as mexiletine), and oral contraceptives. Increased theophylline levels can lead to toxicity, with symptoms such as nausea, vomiting, insomnia, tremors, and potentially life-threatening arrhythmias or seizures. It is essential to monitor theophylline serum levels when initiating or discontinuing these medications.

Conversely, some drugs can decrease theophylline levels, reducing its effectiveness. These include rifampin, phenobarbital, carbamazepine, and phenytoin. Smoking tobacco or marijuana can also lower theophylline levels due to induction of hepatic enzymes. Patients should be advised against starting or stopping smoking without consulting their healthcare provider, as this may necessitate a dosage adjustment.

Additionally, theophylline may interact with beta-blockers, which are used for high blood pressure and heart conditions. Non-selective beta-blockers can potentially negate the bronchodilatory effects of theophylline and may worsen respiratory symptoms. On the other hand, theophylline can also increase the side effects of beta-blockers on the cardiovascular system, such as a decrease in heart rate.

It is also important to consider the additive effects of other central nervous system stimulants, adenosine, and other bronchodilators when taken with theophylline, as these can increase the risk of side effects. Dietary factors, such as a high protein diet or a diet high in carbohydrates, can alter theophylline metabolism and should be discussed with a healthcare provider.

Given the complexity of theophylline pharmacokinetics and its interactions with other drugs, it is recommended that serum theophylline levels be monitored regularly, especially when starting or stopping concomitant medications. Adjustments to theophylline dosing may be necessary to maintain therapeutic levels and avoid toxicity. If you have any questions or require further clarification on managing these drug interactions, please reach out to us at Bayview Pharmacy for professional advice tailored to your specific needs.

Theophylline is a bronchodilator used to treat symptoms of asthma, chronic bronchitis, and emphysema by relaxing muscles in the lungs and chest, making it easier to breathe. Theophylline 50 mg Slow Release (MEM4) Oral Capsules are specially formulated to provide a controlled release of theophylline into the bloodstream over an extended period. This is achieved through the use of Methocel E4M, a type of hydrophilic polymer that forms a gel matrix when it comes into contact with gastric fluids. Methocel E4M is a brand name for hypromellose, also known as hydroxypropyl methylcellulose (HPMC), which is widely used in oral controlled-release formulations.

Upon ingestion, the Methocel E4M in the capsule swells and forms a gel barrier around the theophylline particles. This gel barrier controls the rate at which theophylline is released from the capsule and absorbed into the bloodstream. The rate of drug release is primarily governed by the rate of water penetration into the capsule and the subsequent erosion or dissolution of the gel layer. This mechanism ensures a slow and steady release of theophylline, maintaining therapeutic drug levels for an extended period, typically 12 to 24 hours, depending on the individual's metabolism and the specific formulation of the capsule.

The slow release of theophylline provided by these capsules offers several therapeutic advantages. It helps in maintaining consistent plasma drug concentrations, which is crucial for chronic management of respiratory diseases. This reduces the likelihood of peak-trough fluctuations that can be associated with immediate-release formulations, thereby minimizing the risk of side effects and potentially improving the efficacy of the drug. Additionally, the reduced dosing frequency enhances patient compliance, as patients are required to take the medication less often than immediate-release forms.

For patients and prescribers considering the use of Theophylline 50 mg Slow Release (MEM4) Oral Capsules, it is important to understand that the controlled-release nature of this formulation allows for more convenient dosing schedules, which can lead to better adherence to treatment regimens. However, it is also crucial to follow the prescribed dosing instructions and not to crush or chew the capsules, as this would disrupt the controlled-release mechanism and could result in the rapid release of theophylline, increasing the risk of adverse effects.

Our team of compounding pharmacists is here to provide the information and support you need to ensure the safe and effective use of Theophylline 50 mg Slow Release (MEM4) Oral Capsules.

Theophylline 50 mg Slow Release (MEM4) Oral Capsules are primarily prescribed for respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma, due to their ability to relax the bronchial smooth muscles and improve airway function. However, apart from these indications, this formulation has been researched for potential off-label uses that may benefit other conditions. For example, because theophylline has diuretic effects, it has been considered for the management of conditions that benefit from fluid removal, such as certain types of heart failure where fluid buildup is a concern.

Additionally, some studies have suggested that theophylline may have neuroprotective properties and could potentially be used in the treatment of neurodegenerative disorders like Parkinson's disease, though this is not a standard use and requires further clinical evidence. Its ability to enhance diaphragmatic contractility could also make it a candidate for managing certain types of respiratory failure that involve diaphragmatic weakness. Lastly, theophylline has been noted for its anti-inflammatory effects and is sometimes used in adjuvant therapy for managing complex asthma cases where inflammation is a significant concern.

It's important to note that any off-label use of Theophylline 50 mg Slow Release (MEM4) Oral Capsules should be considered carefully by a healthcare provider, taking into account the patient's overall health, current medications, and the potential benefits versus risks. This slow-release formulation offers the advantage of maintaining more consistent serum theophylline levels, thus minimizing side effects related to peak drug concentrations and improving patient adherence due to less frequent dosing.
