Beneficios clínicos y funcionales de agregar teofilina a la terapia inhalatoria con broncodilatadores de acción corta en pacientes con enfermedad pulmonar obstructiva crónica

Although theophylline is considered a third line bronchodilator drug for the treatment of chronic obstructive pulmonary disease (COPD), it is widely used in Chile, because it is administered orally and has a moderate cost. Aim: To evaluate if theophylline adds clinical and/or functional benefits whe...

Aim: To evaluate if theophylline adds clinical and/or functional benefits when associated to standard recommended inhaled bronchodilator therapy. Subjects and methods: Thirty-eight stable COPD patients who accepted to participate in the study approved by the Ethics Committee of our institution were studied. Using a randomized double-blind placebo-controlled study, theophylline (250 mg) or placebo was administered twice a day for 15 days in addition to inhaled salbutamol and ipratropium bromide. Prior to and at the end of the study, patients underwent: a) a spirometry to evaluate changes in dynamic pulmonary hyperinflation using slow vital capacity (SVC) and inspiratory capacity (IC), b) the 6 min walking distance (6 MWD); and c) measurement of maximal inspiratory and expiratory pressures. Dyspnea and quality of life (QoL) were evaluated using appropriate questionnaires. Results: Compared to placebo, patients on theophylline showed significant increases in SVC (p=0.014), IC (p=0.002), and 6 MWD (p=0.005). They also experienced an improvement in dyspnea (p=0.042) and QoL (p=0.011). All patients improved at least one of these parameters with 53% of the patients showing an improvement in 3 or more. Conclusions: Our results indicate that adding theophylline to standard treatment with inhaled bronchodilators provides additional benefits in stable COPD patients by reducing dynamic pulmonary hyperinflation, improving exercise tolerance, dyspnea and QoL (Rev Méd Chile 2005; 133: 1211-9)info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.133 n.10 20052005-10-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872005001000010es10.4067/S0034-98872005001000010
