Analysis of the Utilization of Antidepressant Drugs in 11 Hospitals from Zhejiang Province during 2013-2017 / 中国药房

ABSTRACT

OBJECTIVE： To investigate the application of antidepressants in Zhejiang province and to provide reference for rational drug use in clinic. METHODS： WHO-recommended defined daily dose （DDD） method was used to statistically analyze consumption sum， main types， defined daily dose system （DDDs）， daily drug cost （DDC） and ranking ratio （B/A value， i.e. consumption sum rank/DDDs rank， B/A＜1 means the price of drugs was higher， whereas the price of drugs was lower） of antidepressant drugs in 11 hospitals from Zhejiang province during 2013-2017. RESULTS： The consumption sum of antidepressants was increased year by year in 11 hospitals from Zhejiang during 2013-2017， and increased from 3 235 200 yuan in 2013 to 4 569 100 yuan in 2017； the proportion of consumption sum of antidepressants in total consumption sum of all drugs kept stable， ranging from 0.47％ to 0.50％. The top 5 drugs by consumption sum were fluoxetine， duloxetine， olanzapine and venlafaxine； consumption sum of escitalopram accounted for a larger increase （proportion ration increased from 8th place in 2013 to first place in 2017）. Within 5 years， DDDs of fluoxetine， paroxetine and sertraline took up the first 3 place； DDC of olanzapine， quetiapine and duloxetine took up the first 3 place； the drugs with B/A value＜1 included duloxetine， olanzapine， venlafaxine and quetiapine， etc； the drugs with B/A value＞1 were paroxetine and sertraline. CONCLUSIONS： The use of antidepressant drugs in 11 hospitals from Zhejiang province is rational in structure； selective 5-hydroxytryptamine （5-HT） reuptake inhibitors （SSRI）， selective 5-HT and noradrenaline reuptake inhibitor （SNRI） take up the predominant place. New antidepressant drug escitalopram shows a good clinical prospect.
