Abstract:
Objective To evaluate the efficacy of ambroxol on community acquired pneumonia (CAP) in elderly patients.Methods Totally 120 patients with CAP were selected and divided into 3 groups:low-dose group (patients received ambroxol 15 mg intravenously,3 times per day,n=40),conventional-dose group (patients received ambroxol 30 mg intravenously,3 times per day,n=40)and control group (patients received routine treatment including antibiotic therapy and oxygen inhalation,n=40).All patients were treated for 7 days.The levels of white blood cell (WBC),high sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) were determined dynamically during the treatment.Results The markedly efficient rate,efficient rate and inefficient rate were 62.5％ (25/40),15.0％ (6/40) and 22.5％ (9/40) in low-dose group,82.5％ (33/40),15.0％ (6/40) and 2.5％ (1/40) in conventional-dose group,40％ (16/40),15.0％ (6/40) and 45.0％ (18/40) in control group,respectively.The total efficient rates were 77.5％,97.5％ and 55.0％ in low dose,conventional dose and control groups,respectively.The markedly efficient rate was higher in lowdose,conventional-dose groups than in control group (x2 =15.29,P＜0.05).There was a significant difference in markedly efficient rate between low dose and conventional-dose groups (x2 =4.01,P＜ 0.05).The total efficient rate was higher in low-dose,conventional-dose groups than in control group (x2 20.22,P＜0.05).There was a significant difference in total efficient rate between low dose and conventional-dose groups (x2=7.31,P＜0.05).Compared with before treatment,the levels of WBC,hs CRP and PCT were decreased in 3 groups after treatment (all P＜0.05).The levels of WBC,hsCRP and PCT were decreased more remarkably in low dose,conventional-dose groups than in control group (all P＜0.05).There was a significant difference in the decrease of WBC,hs-CRP and PCT levels between low-dose and conventional-dose groups (all P＜0.05).Conclusions Conventional dose ambroxol treatment (30 mg,iv,3 times/d) is an efficient therapy for community acquired pneumonia in elderly patients.
