ABSTRACT
Objective To investigate effect of tiotropium bromide combined with formoterol on oxidative stress and lipid peroxidation in peripheral blood in elderly patients with chronic obstructive pulmonary disease.Methods 80 elderly patients with chronic obstructive pulmonary disease from our hospital were selected and divided into conventional group and experimental group, conventional group on the basis of conventional therapy was treated with salmeterol xinafoate and fluticasone propionate powder for inhalation with 2 suction per times, 2 -3 times per day for 14d.Experimental group was treated with tiotropium bromide spray combined with formoterol fumarate powder for inhalation with 2 suction per times, 2-3 times per day for 14 d.7 d for a period of treatment, after 2 courses of the treatment, changes of clinical signs, blood gas levels, peripheral blood oxidative stress products and lipid peroxidation and inflammatory factors were compared before and after treatment.Results Compared with conventional group,the recovery time were shorter(P<0.05) ,and blood gas levels, peripheral blood oxidative stress products and lipid peroxidation, inflammatory factors were lower(P<0.05). Conclusion Tiotropium bromide combined with formoterol can significantly reduce airway hyperresponsiveness, inhibit inflammation, relieve clinical symptoms.And the drug resistance is low, the side effect is small, the clinical curative effect is ideal, may be the clinical treatment effective plan, and has the vital significance.
