Résumé
Objective:To observe the effectiveness and security of piperacillin sodium/sulbactam sodium in the treatment of bacte-rial infections and perform the pharmacoeconomics evaluation. Methods: Totally 126 patients with hand trauma bacterial infections were divided into the control group and the treatment group. The control group was given piperacillin sodium/tazobactam sodium 2. 5g, ivd, bid, while the treatment group was treated with piperacillin sodium/sulbactam sodium 1. 25g, ivd, bid. After 14-day treatment, the clinical therapeutic effect and adverse reactions of the two groups were observed, and the cost-minimization analysis was carried out. Results:The effective rate of the treatment group was 93. 65%while that of the control group was 92. 06%(P>0. 05). The bac-terial clearance rate of the treatment group was 96. 83%while that of the control group was 95. 24% (P>0. 05). The incidence of ad-verse reactions of the treatment group was 4. 76% (3/63) while that of the control group was 9. 52%(P>0. 05). The cost-effective-ness of piperacillin/sulbactam was significantly lower than that of the control group (P<0. 05). Conclusion: The effectiveness and safety of the two groups show no obvious differences in the treatment of hand trauma bacterial infections, and both have good antibacte-rial effect with low incidence of adverse reactions. For the better economic benefits, piperacillin /sulbactam is worthy of promoted ap-plication.
Résumé
Se presentan en este artículo los resultados obtenidos en desarrollo y validación de una metodología analítica para la cuantificación simultánea de piperacilina sódica y tazobactam sódico en inyectables para uso humano. El procedimiento consiste en una separación por cromatografía líquida de alta eficiencia (HPLC) en fase inversa empleando como fase móvil una mezcla de acetonitrilo e hidróxido de tetrabutilamonio 0,005M de pH 5,0 (31:69), una columna C18 a 38°C y detección a una longitud de onda de 220 nm. Se encontró que el método es selectivo, lineal y preciso. Estas características junto con su sencillez permiten que el método sea adecuado y conveniente para el objetivo propuesto. La robustez de la metodología fue también investigada. El método validado se aplicó para la determinación de las dos sustancias en un producto inyectable del mercado colombiano con registro sanitario del Instituto Nacional de Vigilancia y Control de Medicamentos y Alimentos (Invima).
A reverse phase high performance liquid chromatographic method was developed for the simultaneous quantitative assay of sodium piperaciline and sodium tazobactam. The method was validated and then applied to the quantitative determination assay of each of two substances A C18 column stabilized at 38 °C was used and the detection was performed at 220 nm. A mixture of acetonitrile and tetrabutylammonium hydroxide 0,005M pH 5,0 (31:69) was used as mobile phase. The method is selective, linear and shows a good repeatibility. The robustness was also verified. These properties besides their simplicities make it convenient for the objective proposed. The validated method was applied for the simultaneous assay of piperaciline and tazobactam in one market products with sanitary register at Instituto Nacional de Vigilancia y Control de Medicamentos y Alimentos (INVIMA).

Résumé
Objective To compare the clinical efficacy of moxifloxacin vs.cefoperazone sodium/tazobactam sodium in the treatment of genitourinary infection,and provide a reference for clinical rational use of antimicrobial drugs through pharmacoeconomics studies.Methods A total of 115 cases with genitourinary infection were randomly divided into moxifloxacin group (59 cases) and cefoperazone sodium/tazobactam sodium group (cephalosporin group,56 cases) by random digits table method.Moxifloxacin group was treated with moxifloxacin hydrochloride tablets,cephalosporin group was given cefoperazone sodium/tazobactam sodium by intravenous infusion for 7 d.The clinical efficacy and incidence of adverse reaction was compared,and the two drugs were evaluated by pharmacoeconomic study.Results The clinical total effective rate in moxifloxacin group and cephalosporin group was respectively 86.4％ (51/59) and 85.7％(48/56),and bacteriological eradication rate was respectively 89.3％(67/75) and 88.9％(64/72),and the difference between the two groups was not statistically significant (P ＞ 0.05).The incremental cost-effectiveness ratios in moxifloxacin group and cephalosporin group were 2.29 and 21.56,and the difference was statistically significant (P ＜0.01).The incidence of adverse reactions in moxifloxacin group and cephalosporin group was 6.8％ (4/59),3.6％ (2/56),and there was no significant difference (P ＞ 0.05).Conclusion In the treatment of genitourinary infections,moxifloxacin and cefoperazone sodium/tazobactam sodium has equivalent efficacy,but moxifloxacin is good to reduce the cost of treatment and is easy to take,which is better treatment programs.
