Background: There are many factors that effect on the lungs capacity and treatment process in chronic obstructive pulmonary disease (COPD). Smoking, as a risk factor, is important in this process. The aim of this study was to evaluate the efficacy of Salmeterol on some parameters of pulmonary ventilation in smokers and non-smokers patients with COPD.
Materials and Methods: This desiccative analytical study was done on 117 patients with respiratory symptoms of COPD who had referred to an internist during 2010-2013 in Sabzevar city, Iran. Data collection methods include observation, clinical symptoms, and respiratory test (spirometry) that was performed by a physician. Before and after Salmeterol inhalation, pulmonary function tests were performed, and pulmonary parameters FEVI, FVC, FEV1% and PEF were measured and recorded. Data were analyzed using paired t test, and independent t test.
Results: Of 117 patients 75(64%) were male and 42(36%) were female. The mean age of smokers and non-smokers was 42.36±18.20 and 50.14±18.56, respectively; which was statistically significan (P
