ABSTRACT
OBJECTIVE:To provide reference for the improvement of Chinese patent medicine instruction.METHODS:The outpatients were selected randomly from a Third Grade Class A hospital.A questionnaire survey was conducted on the attention degree of the outpatients to Chinese patent medicine instructions when taking medicine orally.The concern content label of patients in 221 Chinese patent medicine instructions were counted,analyzed and graded according to survey results.RESULTS:A total of 515 questionnaires were distributed,and 498 effective questionnaires were collected with effective recovery rate of 96.7％.The results of questionnaire survey showed that the highest concern from the patients was usage and dosage (92.4％),followed by attentions and taboos (88.0％,70.3％).The following items were drug interaction,pregnant and lactating women medication,children medication and the elderly medication (56.2％,46.4％,45.2％,42.4％).Among the description of medication methods (usage and dosage) in 221 Chinese patent medicine instructions,203 prescriptions clearly marked medication times (91.9％),160 clearly marked drug dosage (72.4％) and 36 clearly marked medication course (16.3％).In matters of taboos (attentions,taboos,pregnant and lactating women medication,children medication and the elderly medication),124 prescriptions clearly marked population taboos (56.1％),82 clearly marked symptom taboos (37.1％) and 71 clearly marked diet taboos (32.1％).According to the scoring statistics of 221 Chinese patent medicine instructions,there were 52 instructions with score of 6,followed by 47 instructions with score of 8;there were only 4 instructions with full score (12).CONCLUSIONS:At present,related contents of medication methods highly concerned by the patients are well marked in Chinese patent medicine instructions,especially its guidance is basically able to meet the requirements in respect of medication times.The related contents of medication taboos,which is next only to attention degree of medication methods by patients,is poorly marked.Its guidance remains to be improved.
ABSTRACT
Objective To prepare micronized nimodipine push-pull osmotic pump (PPOP) controlled release tablets . Methods The nimodipine as a model drug ,micronization technique was applied to the PPOP method .Designed and prepared the controlled release of the nimodipine tablet for 12 hours in vitro .The factor f2 was used to evaluate the similarities of differ-ent dissolution profiles ,and the optimal formulation was performed .Results The micronized nimodipine PPOP controlled re-lease tablets were successfully prepared with excellent zero-order release characteristics .The PPOP tablet′s release behavior was close to the zero-order release equation (r= 0 .998 4) .Conclusions The controlled-release formulation was prepared suc-cessfully .Micronized technique combined with the PPOP method significantly increased the release of the nimodipine tablet , the poorly soluble drug ,in vitro .
ABSTRACT
OBJECTIVE:To evaluate the efficacy of acarbose treatment in impaired glucose tolerance (IGT)and provide evi-dence-based reference for the clinical treatment. METHODS:Medline,Cochrane library,PubMed,EMBase,VIP database,CJFD and Wanfang database were retrieved to collect the randomized controlled trials(RCT)of comparison treatment(test group)of acar-bose and placebo(control group)in IGT. After the information collection and quality evaluation,Rev Man 5.0 was conducted for Mata-analysis. RESULTS:26 RCT,involving 2 221 patients were include in total. Meta-analysis result showed,compared with place-bo,acarbose could reduce FPG[WMD=-0.76,95%CI(-0.99,-0.53),P<0.001],2 h PG[WMD=-1.58,95%CI(-1.82,-1.34), P<0.001],HbA1c[WMD=-0.46,95%CI(-0.82,-0.11),P=0.01],BMI[WMD=-1.10,95%CI(-1.77,-0.44),P=0.001], TC[WMD=-0.35,95%CI(-0.59,-0.12),P=0.003],TG[WMD=-0.30,95%CI(-0.44,-0.16),P<0.001] significantly;it had no significant difference on HDL-C[WMD=-0.05,95%CI(-0.11,0.01),P=0.11] and LDL-C[WMD=-0.13,95%CI(-0.31, 0.05),P=0.17]. CONCLUSIONS:Acarbose has better efficacy in the treatment of IGT. Due to the low quality of included studies, it remains to be further verified by RCT with large sample and high quality.
