Preparation and Quality Control of Thermosensitive Meloxicam Hydrogel / 中国药房

OBJECTIVE: To prepare thermosensitive meloxicam hydrogel and establish its quality control method.METHODS: The hydrogel was prepared with poloxamer 407 and poloxamer 188 as base.The content of meloxicam in the thermosensitive gel was determined by UV spectrophotometry.RESULTS: The thermosensitive meloxicam hydrogel was yellowish or flavovirens in color,with its identification and tests all in conformity with the related specification stated in Chinese Pharmacopeia(2005 edition).The linear response range of meloxican was 1.956～19.56 mg?L-1(r=0.999 7).The average recovery was 98.42%(RSD=1.53%).CONCLUSION: The preparative technique is simple,and the quality of the preparation is controllable.

Meta-analysis of Domestic Sparfloxacin for Acute Bacterial Infections with Oral Administration / 中国药房

OBJECTIVE:To assess the clinical efficacy and safety of domestic sparfloxacin for acute bacterial infections.METHODS:Domestic literatures about sparfloxacin for acute bacterial infections were retrieved by computer and their quality was evaluated to extract data(1993～2009).RevMan 4.2.2 software was used for Meta-analysis.RESULTS:A total of 10 RCT were enrolled.The comparisons of 2 groups were homogeneous in terms of clinical cure rate,clinical response rate,bacterial clearance rate and safety.There was statistical significance in comparison of combined effect variable between 2 groups in respect of cure rate,response rate and bacterial clearance rate(P0.05).CONCLUSION:The currently available evidence shows that clinical efficacy of domestic sparfloxacin for acute bacterial infections is better and incidence of ADR was lower.

Preparation and Quality Control of Thermo-sensitive Ornidazole Hydrogel / 中国药房

OBJECTIVE: To prepare thermo-sensitive ornidazole hydrogel and establish its quality control method.METHODS: Thermo-sensitive ornidazole hydrogel was prepared with ornidazole as chief constituent using poloxamer 407 and poloxamer 188 as base.The content of ornidazole in the hydrogel was determined by ultraviolet spectrophotometry.RESULTS: The preparation was white or yellowish semisolid gel,and its test results were up to the related standard specified in Chinese Pharmacopeia(2005 Edition).The linear range of ornidazole was 3.98～43.77 mg?L-1(r=0.999 8),and its mean recovery was 98.52%(RSD=1.1%).CONCLUSION: The preparation is simple and feasible in preparation process,and the quality of the preparation is stable and controllable.

Assay of Compound Alcoholic Solution of Benzoic Acid by Linear Combination Method of Absorbances / 中国药房

We adopted the linear combination method of absorbances to assay the contents of compound alcoholic solution of benzoic acid directly without isolation of its components. The recovery rates of benzoic acid and salicylic acid were 100.97％ (cv=0.86％)and 100.29％(cv=0.82％)respectively.
