Objective:To analyze the volume and rationality of prescribing psychotropic drugs of category Ⅱ in our hospital from 2016 to 2018

and to provide a reference for their clinical use and supervision.Methods:The consumption of psychotropic drugs of category Ⅱ from 2016 to 2018 was collected from the hospital information system（HIS）for statistical analysis of defined daily doses（DDDs）

defined daily dose consumption（DDDc）

and ranking ratio（B/A）.Results:Psychotropic drugs of category Ⅱ accounted for less than 1% of the total drug sales in our hospital

but the percentage increased and the increase accelerated from 2016 to 2018.In these years

the top five psychotropic drugs of category Ⅱ in terms of sales were dezocine injection

midazolam injection

eszopiclone tablet

tramadol hydrochloride injection

and tramadol hydrochloride sustained-release tablet（0.1 g）.The top five drugs in terms of DDDs were estazolam tablet

alprazolam tablet

dezocine injection

eszopiclone tablet

and clonazepam tablet.The top five drugs in terms of DDDc were pentazocine injection

dezocine injection

buprenorphine transdermal patch

midazolam injection

and tramadol hydrochloride injection.Among the top 10 drugs with the highest sales

B/A values of less than 1 were found for dezocine injection

eszopiclone tablet

midazolam injection

tramadol hydrochloride injection

tramadol hydrochloride sustained-release tablet（0.1 g

0.15 g）

and buprenorphine transdermal patch.Conclusion:The consumption of psychotropic drugs of category Ⅱ increased markedly in our hospital from 2016 to 2018

with rational use in most cases.However

some psychotropic drugs of category Ⅱ with high DDDs and DDDc should be kept under strict supervision.Some new drugs and new dosage forms were less used

which requires study of related theories

analysis of causes

and implementation of countermeasures.
