Theophylline Injection (Theophylline Injection) - Summary

 
 



SUMMARY

Theophylline in 5% Dextrose Injection, USP is a sterile, nonpyrogenic solution of Theophylline, Anhydrous, USP in 5% Dextrose Injection. It contains no antimicrobial agents. Theophylline is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste.

Intravenous theophylline is indicated as an adjunct to inhaled beta-2 selective agonists and systemically administered corticosteroids for the treatment of acute exacerbations of the symptoms and reversible airflow obstruction associated with asthma and other chronic lung diseases, e.g., emphysema and chronic bronchitis.

Published Studies Related to Theophylline Injection

Prevention of contrast-induced acute kidney injury by theophylline in elderly patients with chronic kidney disease. [2010.09.29]
Although the optimal strategy for preventing contrast-induced acute kidney injury (CI-AKI) has not yet been established, the current strategy focuses on adequate periprocedural hydration, the use of a low amount of low or iso-osmolar contrast medium, and the application of adjunctive therapies, including hemofiltration, hemodialysis and drugs...

Pharmacokinetics of an extended-release theophylline product in cats. [2007.09.15]
OBJECTIVE: To evaluate the pharmacokinetics of a brand of extended-release theophylline tablets and capsules in healthy cats. DESIGN: Randomized 3-way crossover study... CONCLUSIONS AND CLINICAL RELEVANCE: Daily administration of the brand of theophylline tablets and capsules used in this study at 15 mg/kg (6.8 mg/lb) and 19 mg/kg (8.6 mg/lb), respectively, maintained plasma concentrations within the desired therapeutic range in healthy cats.

Theophylline does not potentiate the effects of a low dose of dexamethasone in horses with recurrent airway obstruction. [2006.11]
REASONS FOR PERFORMING STUDY: Theophylline has been shown to have corticosteroid-sparing effects for the treatment of human asthma. A similar effect, if present in horses, would allow diminishing the dose of corticosteroids administered to equine patients with inflammatory airway diseases... CONCLUSIONS AND POTENTIAL RELEVANCE: Oral theophylline for 7 days did not improve the effects of a low dose of dexamethasone for the treatment of horses with RAO.

Prophylaxis of contrast material-induced nephropathy in patients in intensive care: acetylcysteine, theophylline, or both? A randomized study. [2006.06]
PURPOSE: To prospectively compare the protective effect of acetylcysteine, theophylline, and both agents combined in patients who are admitted to the intensive care unit with at least one risk factor for contrast material-induced nephropathy and who receive at least 100 mL of iodinated contrast medium... CONCLUSION: For prophylaxis of contrast-induced nephropathy in patients who are admitted to the intensive care unit and who receive 100 mL or more of contrast medium, theophylline is superior to acetylcysteine.

Efficacy and safety of intravenous theophylline administration for treatment of mild acute exacerbation of bronchial asthma. [2005.09]
CONCLUSION: These results suggest that IAT is useful for patients with mild acute exacerbation of bronchial asthma and is safe if serum theophylline concentrations are measured.

Clinical Trials Related to Theophylline Injection

Rosiglitazone Versus Theophylline in Asthmatic Smokers [Completed]
Asthmatic smokers display a blunted response to both inhaled and oral corticosteroid treatments and are at increased risk for exacerbations and near fatal asthma. The prevalence of smoking in asthmatics runs between 20-30%. Therefore, new, more efficacious treatments are required.

Recent work has demonstrated a mechanism which may explain steroid resistance. A commonly used drug called theophylline can reverse this steroid resistance in laboratory studies. Another commonly used drug, rosiglitazone can reverse smoking induced lung inflammation in laboratory studies.

The investigators aim to study the effects of these drugs on smoking asthmatics' lung function and other parameters including quality of life and asthma control.

Effects of Low-Dose Theophylline During Chronic Obstructive Pulmonary Disease (COPD) Exacerbations [Completed]
Molecular mechanisms of COPD exacerbations and the modulating effect of low dose theophylline on that inflammation are elucidated in this project. NF-kappa B-dependent pathway and acetylation status of nuclear histones are to be studied. Design: controlled, prospective and randomized study with or without theophylline, a potent HDAC activator. Objectives: 1) To determine NF-kB activation, histone deacetylase (HDAC) and histone acetyl-transferase (HAT) activity in sputum macrophages and blood monocytes during an episode of exacerbation and 3 months later, once stability is achieved. To correlate these measurements with inflammatory and oxidative stress markers and with pulmonary function and clinical variables. 2) To assess the effect of theophylline on previous molecular, functional and clinical data. Method: 25 patients with COPD will be recruited during an episode of exacerbation requiring hospitalization. NF-kB activation, HDAC and HAT activity, markers of inflammation and oxidative stress will be determined with specific assays. These determinations will be repeated once the patient is stable and compared with smokers and non smoker controls with normal lung function

The Effect of Theophylline in the Treatment of Bronchiectasis [Recruiting]
Theophylline was well recommended in the treatment of COPD and asthma. However, there is no supporting evidence for their efficacy in the treatment of bronchiectasis. Our hypothesis is that theophylline will play a role in bronchiectasis. Our purpose is to examine the efficacy and safety of 24 weeks treatment with theophylline in subjects with non-cystic fibrosis bronchiectasis.

The Role of Theophylline Plus Low-dose Formoterol-budesonide in Treatment of Bronchiectasis [Not yet recruiting]
The purpose of this study is to examine the efficacy and safety of 24 weeks treatment with theophylline plus low-dose formoterol-budesonide in subjects with bronchiectasis.

Theophylline in Chronic Obstructive Pulmonary Disease [Recruiting]
This will be a prospective randomized double-blinded parallel group clinical trial evaluating the short-term effects of theophylline therapy on exercise duration and lung function in patients with chronic obstructive pulmonary disease already receiving both tiotropium and a long-acting beta-agonist (salmeterol or formoterol).
