ABSTRACT

Objective To explore the efficacy and safety of compound azintamide enteric‐coated tablets in the treatment of patients with dyspepsia after gastrointestinal surgery .Methods Multicenter , randomized ,double blind ,placebo‐controlled ,parallel controlled method w as applied .From January 2011 to January 2013 , of 240 patients with dyspepsia after gastrointestinal surgery from 12 hospitals in Shanghai were enrolled and divided into medicine treatment group (n= 120) and placebo control group (n= 120 ) ,received compound azintamide enteric‐coated tablets or placebo , respectively . Compound azintamide enteric‐coated tablet (100 mg) or placebo was oral taken each time ,three times per day for four weeks .Total and respective score of dyspeptic symptoms (abdominal distension ,loss of appetite ,early satiety ,belching ,nausea ,abdominal pain or abdominal discomfort) were evaluated prior to study and on the 1st , 2nd , 3rd and 4th week after treatment . On the 4th week after treatment ,the efficacy of the improvement of dyspeptic symptoms was compared between the two groups ,and the safety was also evaluated .The score of the quality‐of‐life was compared between the two groups prior to study and on the 4thweek after treatment .The t‐test was performed for comparison between measurement data ,Chi‐square test was used for count data ,and rank sum test was used for rank data .Results At one week after treatment ,the scores of abdominal distension (4 .61 ± 0 .98 ) ,early satiety (2 .87 ± 0 .64 ) ,belching (3 .03 ± 0 .58) ,abdominal pain or abdominal discomfort (3 .13 ± 0 .79) and total score (18 .32 ± 3 .44) of patients in medicine treatment group were significantly lower than those of placebo control group (8 .83 ± 1 .28、4 .28 ± 0 .61、4 .87 ± 1 .07、5 .46 ± 0 .87、29 .63 ± 5 .50) ,and the differences were statistically significant (t=28 .524、17 .400、16 .453、21 .619 and 18 .983 ,all P 0 .05) .At 2nd ,3rd and 4th week after treatment ,respective score of dyspeptic symptoms and total score of medicine treatment group (2nd week:2.57±1.28,1.87±1.17,1.55±1.27,1.55±1.08,1.09±0.82,1.98±1.02,10.53±4.54,3rdweek:1 .42 ± 0 .60 ,1 .11 ± 0 .45 ,0 .94 ± 0 .37 ,0 .94 ± 0 .41 ,0 .79 ± 0 .31 ,1 .42 ± 0 .55 ,6 .52 ± 2 .41 ,4th w eek:1.13±0.51,0.46±0.12,0.58±0.13,0.38±0.16,0.30±0.07,0.81±0.33,3.65±1.06)wereall significantly lower than those of placebo control group (2nd week:8 .50 ± 2 .61 ,3 .78 ± 2 .01 ,4 .08 ± 2 .14 , 4.73±2.64,2.27±2.13,4.91±2.24,28.25±8.86,3rdweek:7.92±2.51,3.68±1.76,4.08±1.86, 4.71±1.77,2.14±0.83,5.01±1.31,27.54±8.09,4th week:7.63±2.37,3.67±1.63,3.92±2.08, 4 .66 ± 2 .95 ,2 .14 ± 1 .65 ,4 .67 ± 2 .34 ,and 26 .68 ± 7 .45) ,and the differences were statistically significant (all t=0 .000 ,all P<0 .01) .At 4th week after treatment ,the total efficacy of total score improvement of dyspepsia symptoms in medicine treatment group was 86 .21% (100/116) ,which was significantly better than that of placebo control group (39 .16% (47/120)) ,and the difference was statistically significant (Z=9 .464 ,P<0 .01) .The total score of quality of life in medicine treatment group was significantly lower than that of placebo control group (12 .24 ± 4 .30 and 22 .13 ± 6 .18) ,and the difference was statistically significant (t=14 .225 , P< 0 .01 ) .No adverse events was observed in both groups during treatment period . Conclusion Compound azintamide enteric‐coated tablets may effectively improve dyspeptic symptoms and quality of life in patients with dyspepsia after gastrointestinal surgery ,and with good safety .
