Abstract: Objective To discuss the rational use of antibiotic sequential therapy in the elderly hospitalized with acute lower respiratory tract infection.Methods Using a clinical prospective intervention study of random sample contrast and minimum cost analysis of pharmacoeconomic compared the clinical curative effect of two kinds of therapy methods including intravenous-oral sequential therapy group(sequential group)and continuous intravenous infusion therapy group(intravenous group).Meanwhile,the differences of two groups in the bacterial clearance rate,treatment time of intravenous infusion and length of hospitalization day were also investigated. Furthermore the costs of antibiotics of two groups were evaluated as well in the pharmacoeconomic. Results Compared with two therapies,it was shown equivalence in bacteriology and clinical outcome. Pharmacoedynamics of them were nearly same. There was no significant difference(P>0.05).In the clinical curative effect,two therapies' bacteria clearance,the times of restoring to normal of temperature,blood routine examination and chest X-ray were practically closed to each other,difference was in significant(P>0.05).However,the time of intravenous infusion therapy time and the length of hospitalization day had notable difference,and antibacterial cost of sequential group Was obviously lower than those of intravenous group,there were significant difference(P<0.05).Conclusion Sequential therapy was safe,operative,and had more reasonable cost-effect ratio in treating the elderly with acute lower respiratory tract infection. Moreover the optimum time from intravenous infusion therapy switching to oral antibiotics therapy was about 7 days.
