title: [Analysis on the current use and trend of drugs for digestive system through comprehensive statistics index, in Hangzhou].
abstract: OBJECTIVE
  To investigate the use and trend of drugs on digestive system in Hangzhou area, under the comprehensive statistics index (CSI).
  
  
  METHODS
  Using the analytical method related to the sum of consumption and CSI, the application of digestive system drugs of different manufacturers in Hangzhou from 2005 to 2007 was analyzed.
  
  
  RESULTS
  Other than H2 receptor antagonist, the total consumption of digestive system drugs increased yearly, in terms of the total consumption, the first 4 leading ones were proton pump inhibitors, micro ecology medicines, antiemetic drugs and gastroprokinetic agents. The Laspeyres index of drugs on digestive system increased to different extent. The Laspeyres indices of proton pump inhibitors, probiotics, antiemetic drugs and gastroprokinetic agents were 1.396 50, 1.020 42, 1.728 90, 1.148 50 in 2006 while 2.081 10, 1.217 55, 2.223 50, 1.156 60 in 2007, respectively.
