Objective To comprehensively assess the strengths and weaknesses of the 24 antihypertensive drugs procured as Volume-based Procurement(VBP)and innovator drugs by using quantitative evaluation system,and to provide a reference for doctors and patients in medication guidance and pharmaceutical decision-making.Methods The Quantitative Evaluation Criteria in the"Quick Guide to Drug Evaluation and Selection in Chinese Medical Institutions"were refined and optimized.The 24 selected VBP and innovator antihypertensive drugs were quantitatively evaluated according to the optimized quantitative evaluation system with the help of Chinese and English databases such as China Knowledge Network,Wanfang data,Wipunet,Embased,PubMed,and Metstr,as well as guideline search tools such as Meikang MCDEX,Drugwise Data,Up To Date,Medical Pulse and other databases etc.Results Among the 24 antihypertensive drugs,only four innovator drug evaluation scores were higher than those of drugs selected as VBP,namely felodipine tablets,Fosinopril sodium tablets,indapamide extended-release capsules,Irbesartan hydrochlorothiazide tablets.there were five main differences in the evaluation scores,namely economy,consistency evaluation,drug expiry date,global use,and the status of manufacturing enterprises.It was found that 83%of the VBP drugs had higher evaluation scores than those of the innovator drugs.The economic score of the innovator drug was low,and the difference in the scores was between 1-11 points.Conclusion By using the quantitative evaluation system to evaluate the antihypertensive drugs,the advantages and disadvantages of the innovator and VBP antihypertensive drugs can be assessed comprehensively,and the digital characteristics of antihypertensive drugs can be given,and the evaluation score can provide the reference basis for the guidance and decision-making of medication for doctors and patients.

OBJECTIVE： To standardize the management of temporary drug purchase， and to provide reference for drug selection in Hospital Pharmaceutical Administration and Drug Treatment Committee （Pharmaceutical Association）. METHODS： Clinical pharmacists set up drug quantitative scoring table according to the 10 attributes of drugs as effectiveness， safety， economy， etc. 15 temporary purchased drugs submitted by departments in Oct. 2018 were graded according to the rules of the scoring table， and the evaluation results were fed back to Pharmaceutical Association. A retrospective evaluation of 20 temporary purchased drugs which were discussed at the Pharmaceutical Association from Jul. to Sept. 2018 was made according to previous approval model without using drug quantitative scoring table. The effect of pre-intervention was evaluated after using drug quantitative scoring table. RESULTS： Among 15 temporary purchased drugs， 2 of them scored below 60， and the unqualified rate was 13.3％. It suggested that 2 drugs could not be discussed at the meeting. Among 20 temporary purchased drugs that have been discussed at the meeting， 9 of them scored below 60， with the unqualified rate of 45.0％， suggesting that 9 drugs may have wasted the workload of the Pharmaceutical Association. CONCLUSIONS： Drug quantitative scoring table can play a pre-intervention role in the scoring of temporary purchased drugs to a certain extent. At the same time， the table can also be used as a relevant reference for hospital drug evaluation. It is helpful to optimize hospital drug use list and improve the level of rational drug use in clinic.

OBJECT IVE To e stablish the method for simultaneous determination of levetiracetam and carbamazepine concentrations in human plasma. METHODS After plasma samples were precipitated with methanol ，using carbamazepine-D 10 as the internal standard ，the concentrations of levetiracetam and carbamazepine were determined by high performance liquid chromatography-tandem mass spectrometry （HPLC-MS/MS）. The determination was performed on XBridge BEH C 18 column with methanol-0.1％ formic acid as mobile phase （gradient elution ）at the flow rate of 0.35 mL/min. The column temperature was set at 40℃，and sample size was 2 μL. With electrospray ion source，a multiple reaction monitoring mode was used for positive ion scanning；the detected ion pairs for quantitative analysis were m/z 171.3→126.3（levetiracetam），m/z 237.1→194.1（carbamazepine）， 247.1→204.1（internal standard ）. RESULTS The linear range of the concentrations of levetiracetam and carbamazepine were 0.5-50 and 0.2-20 μg/mL（r＝0.997 3 and 0.998 5），respectively；the lower quantitative limits were 0.5 and 0.2 μg/mL，respectively. RSDs of intra-day and inter-day were all no more than 10.00％. RE of intra-day and inter-day were within ±4.00％；the average extraction recoveries rate were 95.60％-105.00％；the average internal standard correction matrix factors were 98.40％-110.00％； RSDs of stability tests were all not higher than 5.60％. The concentrations of levetiracetam and carbamazepine in the plasma of 22 patients measured by this method were 3.36-40.90 and 3.64-9.93 μg/mL，respectively. CONCLUSIONS The established method for determining the concentration of levetiracetam and carbamazepine in human plasma is f ast，sensitive，accurate and stable ，and can be used for the monitoring of plasma concentration and pharmacokinetic study in epilepsy patients.

OBJECTIVE：To promote the safe use of severe ADR-inducing drugs in special population in our hospital. METHODS：According to detailed quantitative scoring rules of Quick Guide for Drug Evaluation and Selection in Chinese Medical Institutions，comprehensive evaluation database of drugs in our hospital was established. Drugs with ADR rating or ADE general terminology standard rating of 1，2，3 and 4 under the "safety" dimension were obtained from the database. According to the difference of the incidence of ADR ，4 kinds of severe ADR-inducing drugs ，such as very common （incidence≥10％），common （incidence 1％-＜10％），occasional（incidence 0.1％-＜1％）and rare （incidence ＜0.1％），were obtained. According to the quantitative scores of these 4 kinds of drugs in six special groups ，such as children ，pregnant women ，lactating women ，the elderly，patients with abnormal liver function ，and patients with abnormal kidney function ，the feasibility for special population to use drugs that cause severe ADR was analyzed. RESULTS ：Among 1 172 chemical drugs in drug comprehensive evaluation database of our hospital ，18，73，61，and 357 kinds can cause very common ，common，occasional and rare severe ADR ， respectively. Among them ，the incidence of severe ADR caused by tumor drugs was high ，so it was necessary to pay close attention to the use of tumor drugs in special populations. Totally 173 kinds of drugs were prohibited for children because the instructions clearly showed organ toxicity ，cytotoxicity and there were no guidelines recommending their use in children ，so the clinical medication should be used with extraordinary caution. There were 278 and 228 drugs prohibited for pregnant women and lactating women，which were prohibited for pregnant or lactating period due to embryonic toxicity and reproductive toxicity. There were 13 prohibited drugs for the elderly ，most of which were specialized drugs. Five kinds of drugs were prohibited in patients with abnormal liver function and seven were prohibited in patients with abnormal kidney function ，most of which were tumor drugs with strong hepatorenal toxicity. CONCLUSIONS ：Established quantitative score system can provide effective guidance for the safe use of severe ADR-inducing drugs among 6 special populations as children ，pregant women ，lactating women ，the elderly ，the patients with abnormal liver function and the patients with renal
