ELIXOPHYLLINE SUMMARY

ELIXOPHYLLIN®
(brand of theophylline anhydrous)
ELIXIR

Theophylline is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste.

Theophylline is indicated for the treatment of the symptoms and reversible airflow obstruction associated with chronic asthma and other chronic lung diseases, e.g., emphysema and chronic bronchitis.

Published Studies Related to Elixophylline (Theophylline)

Beneficial effects of theophylline infusions in surgical patients with intra-abdominal hypertension. [2011.08]
BACKGROUND: Intra-abdominal hypertension (IAH) can cause high mortality. Recently, we found that IAH was associated with increased serum levels of adenosine and interleukin 10. Our present "hypothesis-generated study" was based on the above mentioned results... CONCLUSIONS: Adenosine receptor antagonism with T following IAH diagnosis resulted in markedly reduced mortality in patients with moderated IAH (<20 mmHg). Theophylline-associated mortality reduction may be related to improved renal perfusion and improved MAP, presumably caused by adenosine receptor blockade. Because this study was not a randomized controlled study, these compelling observations require further multicentric clinical confirmation.

Study investigating pharmacokinetic interaction between theophylline and roflumilast in healthy adults. [2011.07]
OBJECTIVE: To investigate whether a pharmacokinetic drug-drug interaction exists between theophylline (THEO), a CYP1A2 substrate with a narrow therapeutic index, and the concomitant substrate roflumilast (ROF), a novel selective PDE4 inhibitor partially metabolized by CYP1A2... CONCLUSIONS: Neither ROF nor its main metabolite had any impact on the metabolism of the concomitant CYP1A2 substrate THEO in humans. Though co-administration of THEO resulted in a minor increase (28%) in total ROF exposure, no safety or tolerability concerns and no altered total PDE4 inhibition of both ROF and R-NO, were observed.

Prevention of contrast-induced acute kidney injury by theophylline in elderly patients with chronic kidney disease. [2010.11]
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...

Adenosine receptor inhibition with theophylline attenuates the skin blood flow response to local heating in humans. [2010.09]
Mechanisms underlying the robust cutaneous vasodilatation in response to local heating of human skin remain unresolved. Adenosine receptor activation has been shown to induce vasodilatation via nitric oxide, and a substantial portion of the plateau phase to local heating of human skin has been shown to be dependent on nitric oxide...

Clinical Trials Related to Elixophylline (Theophylline)

The Effect of Theophylline in the Treatment of Bronchiectasis [Completed]
Theophylline was well recommended in the treatment of chronic obstructive pulmonary disease (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.

Theophylline and Steroids in Chronic Obstructive Pulmonary Disease (COPD) Study [Recruiting]
The aim of this multi-centre, double blind, randomised, controlled trial (DBRCT) is to assess the effect of low dose theophylline, singly and in combination with low dose oral prednisone, on COPD (Chronic Obstructive Pulmonary Disease) exacerbations, quality of life and secondary clinical outcomes compared with usual therapy and placebo over 48 weeks of treatment. Approximately 2400 symptomatic patients with COPD will be recruited in China for comparison of low dose theophylline versus placebo and low dose theophylline + low dose prednisone The primary end-point for this study is the difference between the three treatment groups in

- COPD exacerbation rate

- Time to first severe exacerbation requiring hospitalisation or death

The Role of Theophylline Plus Low-dose Formoterol-budesonide in Treatment of Bronchiectasis [Completed]
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.

Drug Interaction Study of Colchicine and Theophylline [Completed]
Colchicine is a supressor of hepatic CYP1A2 and theophylline is a sensitive CYP1A2 probe substrate. When the two are co-administered the potential exists for a clinically significant drug interaction. This study aims to determine the effect of steady-state colchicine on the pharmacokinetics of theophylline administered as a single dose. A secondary goal is to evaluate the safety and tolerability of this regimen in healthy volunteers. All study subjects will be monitored for adverse events throughout the entire study period.

A Phase I Dose Escalation Study of Erlotinib in Combination With Theophylline [Recruiting]
This study is to determine the use of theophylline in patients with NSCLC and advanced solid malignancies and whether treatment with theophylline will help lower or diminish the side effect of diarrhea in patients taking erlotinib. Patients will be enrolled in one of two parts of the study to verify the lowest dose of theophylline that is effective and the highest dose of erlotinib that can be tolerated with theophylline. If this study shows that theophylline is able to inhibit erlotinib induced diarrhea, it will help demonstrate that patients using the tyrosine kinase inhibitor (TKIs), erlotinib, can use it effectively at higher doses without experiencing severe diarrhea.
