Theophylline 100 mg/5 mL Oral Liquid is a carefully crafted medication designed for oral use, particularly beneficial for patients who experience difficulty swallowing pills or tablets, such as children and the elderly. This liquid formulation ensures precise dosing and ease of administration, which is crucial for maintaining the therapeutic effectiveness of theophylline. Theophylline is a bronchodilator that belongs to the class of drugs known as methylxanthines. It works by relaxing the smooth muscles of the bronchial airways and pulmonary blood vessels, thereby reducing airway resistance and improving airflow to the lungs. This mechanism of action makes it an effective treatment for respiratory diseases such as asthma, chronic bronchitis, and emphysema, where bronchoconstriction and airway obstruction are common problems.

Theophylline's therapeutic effects are dose-dependent, and maintaining a therapeutic plasma concentration is essential for optimal efficacy and minimizing side effects. The liquid form of theophylline allows for flexible dosing adjustments, which is particularly important given the narrow therapeutic index of the drug. Patients and prescribers should be aware that theophylline levels can be influenced by various factors, including smoking, diet, and interactions with other medications. Therefore, regular monitoring of theophylline blood levels is recommended to ensure safety and effectiveness.

For patients, it is important to adhere to the prescribed dosing schedule and to be aware of potential side effects, which may include nausea, vomiting, headache, insomnia, and palpitations. In severe cases, theophylline toxicity can occur, presenting with symptoms such as seizures or arrhythmias. Prescribers should consider the patient's overall clinical condition, including any comorbidities and concurrent medications, when initiating and adjusting theophylline therapy. Additionally, patient education on the proper administration of the oral liquid, storage conditions, and the importance of regular follow-up appointments is crucial for the successful management of their respiratory condition.

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. When considering the use of theophylline 100 mg/5 mL oral liquid, it is important to be aware of potential drug interactions that can affect the efficacy of the medication or increase the risk of adverse effects.

One major interaction is with other medications that affect the cytochrome P450 enzyme system, particularly CYP1A2, CYP3A4, and CYP2E1. Drugs that inhibit these enzymes, such as cimetidine, fluvoxamine, and erythromycin, can decrease the metabolism of theophylline, leading to increased theophylline levels and potential toxicity. Symptoms of theophylline toxicity include nausea, vomiting, insomnia, tremors, and, in severe cases, seizures and arrhythmias. Conversely, medications that induce these enzymes, such as rifampin, phenobarbital, and smoking (tobacco induces CYP1A2), can lower theophylline levels, reducing its effectiveness.

Other notable interactions include the concurrent use of theophylline with adenosine, as theophylline can block the effects of adenosine, which is sometimes used in medical tests or to treat certain types of heart rhythm problems. Additionally, combining theophylline with beta-blockers for high blood pressure or heart conditions can reduce the effectiveness of both drugs and may worsen breathing issues.

Fluoroquinolone antibiotics, such as ciprofloxacin or levofloxacin, can also increase theophylline levels, necessitating careful monitoring of theophylline concentrations in the blood when starting or stopping these antibiotics. Theophylline may also interact with certain dietary supplements and foods; for example, caffeine can increase the side effects of theophylline because both substances are metabolized similarly.

It is crucial for patients to inform their healthcare provider of all medications, supplements, and over-the-counter drugs they are taking, as well as any changes in their health status, including the development of viral or bacterial infections, which can alter theophylline metabolism and clearance. Regular monitoring of theophylline blood levels is recommended to ensure therapeutic levels are maintained and to avoid toxicity.

Patients should also be advised to avoid smoking and to limit caffeine intake while taking theophylline, as these can interact with the medication and affect its levels in the body. If you have any questions or concerns about the use of theophylline 100 mg/5 mL oral liquid or potential drug interactions, please reach out to us at Bayview Pharmacy for further assistance.

Theophylline is a bronchodilator that is used to treat symptoms of asthma, chronic bronchitis, emphysema, and other lung diseases. It works by relaxing the smooth muscles of the bronchial airways, thereby reducing airway constriction and making it easier to breathe. Theophylline achieves this by inhibiting the enzyme phosphodiesterase, which leads to an increase in cyclic AMP (cAMP) levels. Elevated cAMP levels cause relaxation of bronchial smooth muscle and inhibition of the release of pro-inflammatory mediators from mast cells in the airways.

In addition to its bronchodilatory effects, theophylline has anti-inflammatory properties and can enhance the strength of diaphragmatic contractions, thus aiding in the respiratory effort. Theophylline's narrow therapeutic index necessitates careful dosing and monitoring of blood levels to avoid toxicity. Symptoms of theophylline overdose can include nausea, vomiting, insomnia, seizures, and arrhythmias.

The formulation of theophylline as a 100 mg/5 mL oral liquid is particularly beneficial for patients who have difficulty swallowing pills, such as young children or elderly patients. The liquid form allows for flexible dosing, which is essential for theophylline due to its narrow therapeutic range. The liquid formulation also ensures that the medication is absorbed quickly and efficiently, as it does not require dissolution like solid dosage forms. This can be particularly important during acute exacerbations of asthma or COPD when rapid symptom relief is necessary.

It is important for prescribers to consider the patient's weight, age, and severity of symptoms when determining the appropriate dose of theophylline. Regular monitoring of serum theophylline levels is recommended to ensure therapeutic levels are maintained and to avoid toxicity. Patients should be advised to take the medication consistently with respect to meals and to avoid consuming large amounts of caffeine, as it can increase theophylline levels and the risk of side effects.

For patients and prescribers wanting to use this formulation, it is crucial to understand the importance of adherence to dosing instructions and the need for regular monitoring.

Our team of compounding pharmacists is here to support you with the information and guidance necessary to ensure safe and effective treatment.

Theophylline, traditionally used as a bronchodilator for treating lung diseases like asthma and chronic obstructive pulmonary disease (COPD), has a range of other potential uses due to its pharmacological profile. This drug acts by inhibiting phosphodiesterase, thereby increasing intracellular cyclic AMP, and also by antagonizing adenosine receptors. Because of these actions, other off-label uses for theophylline have been explored, due to its potential anti-inflammatory effects and ability to enhance diaphragmatic contractility and stimulatory effect on the central nervous system.

In addition to its respiratory applications, theophylline has been utilized in the treatment of apnea of prematurity in neonates. Its ability to stimulate the breathing center may decrease the frequency and severity of apneic episodes. Another investigational use is in the management of pulmonary hypertension, where it may work to reduce pulmonary arterial pressure and improve cardiac output. However, these applications would typically require careful dose adjustments and monitoring due to theophylline's narrow therapeutic index and the potential for significant side effects.

Some studies also suggest a role for theophylline in the treatment of Parkinson's disease, with the premise that adenosine antagonism could have favorable effects on motor symptoms, although more substantial evidence is needed to support this use. Additionally, in a cardiovascular context, though not commonly used, theophylline has been explored for its ability to improve cardiac function in patients with congestive heart failure, as well as for treating bradyarrhythmias.

Lastly, theophylline has demonstrable anti-inflammatory properties which have led to exploratory use in both systemic and topical formulations for various dermatologic conditions, such as atopic dermatitis and psoriasis, though again, more research is needed to establish its efficacy and safety for these indications. It's worth noting that the utility of theophylline in these additional roles is still considered experimental and should be approached with caution, usually under specialist supervision or within the context of clinical trials.
