(Theophylline Tablets USP)
ACCUDOSE® Tablets
IMMEDIATE-RELEASE BRONCHODILATOR

Theophylline is structurally classified as a methylxanthine.

Quibron®-T is an oral bronchodilator in an immediate-release formulation in the ACCUDOSE® Tablet design. With functional trisects and bisects, Quibron®-T Tablets can be accurately divided into 100-, 150-, and 200-mg segments to provide a variety of dosing increments, as required.

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 Quibron-T (Theophylline)

Effect of low-dose theophylline plus beclometasone on lung function in smokers with asthma: a pilot study. [2009.05]
Smoking is common in asthma and is associated with worse asthma control and a reduced therapeutic response to corticosteroids. The present authors hypothesised that treating smokers with asthma with low-dose theophylline added to inhaled corticosteroids would enhance steroid sensitivity and thereby improve lung function and symptoms.

Low-dose theophylline enhances the anti-inflammatory effects of steroids during exacerbations of COPD. [2009.05]
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by an abnormal inflammatory response mainly to cigarette smoke that flares up during exacerbations of the disease (ECOPD). Reduced activity of histone deacetylases (HDAC) contributes to enhanced inflammation in stable COPD. It was hypothesised that HDAC activity is further reduced during ECOPD and that theophylline, an HDAC activator, potentiates the anti-inflammatory effect of steroids in these patients. A study was performed to investigate HDAC activity during ECOPD and the effects of theophylline on the anti-inflammatory effects of steroids in a randomised single-blind controlled study... CONCLUSIONS: During ECOPD, low-dose theophylline increases HDAC activity and improves the anti-inflammatory effects of steroids. Trial registration number: NCT00671151.

Treatment of moderate chronic obstructive pulmonary disease (stable) with doxofylline compared with slow release theophylline--a multicentre trial. [2008.12]
An open, randomised trial was conducted at Burdwan Medical College and Midnapore Medical College in West Bengal to investigate therapeutic efficacy and tolerability of doxofylline compared with slow release theophylline in 75 patients (45 males and 30 females) aged between 40 and 70 years who had been suffering from moderate chronic obstructive pulmonary disease...

A randomized controlled trial of theophylline versus CO2 inhalation for treating apnea of prematurity. [2008.10]
OBJECTIVE: To determine whether inhalation of 0.8% CO(2) in preterm infants decreases the duration and rate of apnea as effectively as or better than theophylline with fewer adverse side effects... CONCLUSIONS: Our findings suggest that inhaled low (0.8%) CO(2) concentrations in preterm infants is at least as effective as theophylline in decreasing the duration and number of apneic episodes, has fewer side effects, and causes no changes in CBFV. We speculate that CO(2) may be a better treatment for apnea of prematurity than methylxanthines.

Low-dose theophylline reduces symptoms of acute mountain sickness. [2008.09]
OBJECTIVE: Headache, nausea, and sleeplessness at altitude [acute mountain sickness (AMS)] are major health problems for several million mountain recreationists who ascend to high altitudes each year. We aimed to test the efficacy of low-dose, slow-release theophylline for the prevention of AMS in a placebo-controlled, double-blind, randomized trial... CONCLUSIONS: Low-dose, slow-release theophylline reduces symptoms of AMS in association with alleviation of events of periodic breathing and oxygen desaturations.

Clinical Trials Related to Quibron-T (Theophylline)

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.

All-trans Retinoic Acid, and Arsenic +/- Gemtuzumab and Theophylline [Recruiting]
The goal of this clinical research study is to learn if starting arsenic trioxide (ATO) therapy on Day 1 rather than Day 10 is more effective in treating patients with newly-diagnosed acute promyelocytic leukemia (APL).

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).

Theophylline in Treating Cancer Patients With Shortness of Breath [Active, not recruiting]
RATIONALE: Theophylline may help to relieve shortness of breath in patients who have cancer. It is not yet known whether theophylline is more effective than no further treatment for shortness of breath.

PURPOSE: Randomized phase III trial to determine the effectiveness of theophylline in treating shortness of breath in patients who have cancer.

Theophylline in Treating Patients With In Situ, Stage I, or Stage II Chronic Lymphocytic Leukemia [Completed]
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of theophylline in treating patients who have in situ, stage I, or stage II chronic lymphocytic leukemia.

Quibron-T review by 52 year old female patient

  Rating
Overall rating:  
Effectiveness:   Marginally Effective
Side effects:   No Side Effects
  
Treatment Info
Condition / reason:   asthma
Dosage & duration:   300 mg 2x day taken daily for the period of about 10 years
Other conditions:   migraines, depression
Other drugs taken:   birth control, proventil inhaler
  
Reported Results
Benefits:   the medication kept my asthma under control or so i thought. as an aside, i still have a few left and every so often if i am out of my migraine medication, i will take a theodur and it seems to alleviate the headache. it was inexpensive.
Side effects:   while I was on it, i never really experienced any side effects. except one time when i accidently took too much and became dizzy and nauseaus. when i went off it i suffered two weeks of migraines due to withdrawal.
Comments:   i took 300 mg. twice a day and also used an inhaler regularly. i assumed it was as good as it gets. my new asthma specialist determined i had suffered some loss of lung function as the asthma had not been controlled as well as it could have been. i had to have regular blood work to determine the levels were right.
