Abstract:

In a single-blind crossover study, two slow release theophylline preparations were evaluated in 18 patients with chronic bronchitis or asthma without cardiac, renal or liver disease. After randomization into two groups, patients were treated, in a crossover study design, with 600 mg choline theophyllinate or 300 mg anhydrous theophylline administered orally every 12 h for 7 days. A 2-day washout period separated the two periods of treatment evaluation. Blood samples in which plasma theophylline concentration was to be measured were taken at 7.30 a.m., 2.00 p.m. and 7.30 p.m. during the last 5

Abstract:

Theophylline and aminophylline (i.e., the soluble complex of theophylline with ethylenediamine) have been used in the treatment of respiratory diseases such as asthma and chronic obstructive pulmonary disease for more than 90 years. Theophylline’s narrow therapeutic index and side effects, as well as the discovery of more potent and safer bronchodilators, made it to fall out of favour with healthcare professionals and patients. New scientific knowledge on the molecular mechanism of action of theophylline, along with increasing clinical evidence suggest that theophylline should be exploited as

They all received three preparations (aminophylline by intravenous infusion, lysine theophyllinate orally in solution and slow release theophylline orally as capsules) in a single dose of 100 mg active ingredient in a crossover design. Plasma theophylline concentrations, determined by a fluorescent polarization immunoassay, were evaluated both by compartmental and non-compartmental analysis. After administration of slow release theophylline, its maximum plasma concentration and the time needed to reach this were (± SD) 3.19 ±

Abstract:

In asthma therapy, the use of theophylline to prevent bronchial spasm and glucocorticoids to decrease inflammation is widely indicated. Apart from the acute asthma attack oral theophylline is treated for chronic therapy in order to minimize inflammation and to enhance the efficiency of corticosteroids and recover steroids’ anti-inflammatory actions in COPD treatment. The preferred application route for respiratory disease treatment is by inhalation, such as dry powder inhalers (DPI) being the delivery systems of first choice. As shown recently, there is an advantageous effect if the drugs are

This thesis examines the effects of continuous theophylline pretreatment on the A$ sb2$ adenosine receptor system in cultured murine neuroblastoma cell lines, which either do or do not also express A$ sb1$ adenosine receptors. N-Ethylcarboxamido adenosine (NECA) stimulates cAMP accumulation and binds to A$ sb2$ receptors in a saturable and biphasic fashion in both types of cell cultures. Sixteen hours of theophylline treatment led to a significant increase in the number of low affinity A$ sb2$ binding sites, as well as a potentiation of NECA-stimulated cAMP accumulation, regardless of whether
