Fabbri, M.D. For the POET-COPD Investigators: Tiotropium versus Salmeterol for preventing Exacerbations of COPD Chronic obstructive pulmonary disease is a respected reason behind disability and death worldwide.1-3 Exacerbations of COPD indicate instability or worsening of the patient’s clinical status and progression of the condition and have been associated with the advancement of complications, an elevated threat of subsequent exacerbations, a worsening of coexisting conditions, reduced health status and physical activity, deterioration of lung function, and an elevated risk of death.4-7 Preventing exacerbations therefore constitutes a major goal of treatment.1,2 Comparative studies have indicated that tiotropium is normally connected with a greater reduction in the risk of exacerbations and exacerbation-related hospitalizations than is salmeterol, even though differences were not significant.13,14 They were short-term studies and weren’t designed and powered to detect a notable difference in the risk of exacerbations.

All reported P ideals are two-tailed, and a P worth of significantly less than 0.05 was thought to indicate statistical significance. Outcomes Subjects From 2007 through April 2010 July, we enrolled 4877 subjects, of whom 4855 underwent genotyping and were contained in the 2-month follow-up . There have been about equal amounts of women and men, with a mean age group of 56.5 years for all subjects . Indications for carbamazepine treatment included epilepsy , neuralgia , diabetes-related neuropathic pain , tinnitus , and bipolar disorder or other psychiatric disorders .
