Introduction: obstructive lung diseases are common in patients older than 40 years and cause high morbidity and mortality worldwide. The patterns of drugs prescription for its treatment in Colombian patients are described in this study. Methods: descriptive observational study with patients over 40 years of both sexes, members of the General System of Social Security in Health, in continuous treatment with bronchodilators and / or inhaled steroids between September and December 2013, selected from a dispensing database of 6.5 million people. Sociodemographic and pharmacological variables (drugs with defined daily doses), concomitant medications and co-morbidities were collected. Analysis using SPSS 22. Results: A total of 6856 patients were included with a mean age of 73.8±11.3 years, 54% were women. Of the total of patients, 17.2% received monotherapy and 82.8% combined therapy. 74.3% of subjects received β2-adrenergics, most (81.5%) short-acting bronchodilators, while33.3% long acting bronchodilators. 73.1% received anticholinergics distributed between ipratropium (87.1%) and tiotropium (16.9%) and 71.7% received inhaled steroids. The medications that were most often concomitantly prescribed, were antihypertensive (68.9%), antiulcerants (56.1%) and lipid lowering drugs (46.2%). To be between 40 and 55 or over 80 years, receive any concomitant medication, inhaled corticosteroid use, bronchodilator monotherapy use and being treated in Bogota and Cali, was statistically significantly associated with lower risk of receiving long-acting bronchodilators. Conclusions: the prescription of short-acting bronchodilators predominate despite the limited clinical benefit reported. Most bronchodilators are used at higher than recommended doses. It is necessary to establish educational strategies to improve prescribing habits. (Acta Med Colomb 2015; 40: 218-226).
