Filters (0.2 microns pore size) were challenged with high (up to 5* 10(5) EU) levels of bacterial endotoxin. When the endotoxin was dispersed in water, a more than 10,000 fold reduction of the endotoxin was obtained, whereas the reduction was only a factor 20 when Ringer's solution was used to disperse the endotoxin. Retention of bacteria was dependent on the type of organism, the pore size of the filter and the suspending liquid.

In principle, the open-ampoule production technology should lead to better controlled production process. To test this hypothesis and quantify the possible qualitative differences in the manufactured ampoules, a suitable experimental design was set up. The two ampoule production processes have been compared on the basis of the visible particulate burden. Two batches of ampoules filled with water for injections were produced for each type of process, following conventional industrial procedures. Two samples of 20,000 units were taken from each batch and inspected with different automatic inspection systems: two Brevetti CEA machines (S1, S2--light scattering) and two EISAI machines (S3, S4--light absorbtion). The comparison between the processes was based on the rejection percentage. On both inspection machines the open-ampoule production samples present rejection percentages (ranging from 0.154% to 1.248% rejection percentages) which, on average, are lower than those detected in closed-ampoule production (ranging from 1.434% to 3.86% rejection percentages). The difference between the two processes is even more marked if we also consider the data obtained using inspection machines S3 and S4. The substantial differences in performance of the four inspection machines stress the need to provide for adequate validation procedures.</p>","PeriodicalId":16667,"journal":{"name":"Journal of parenteral science and technology : a publication of the Parenteral Drug Association","volume":"47 5","pages":"265-9"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19251319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A significant decrease in the pH of the mixture containing the trace elements as chlorides was noted after one week of storage at both temperatures. Particle size analysis revealed no significant variations between the two formulations after one week of storage. Flocculation kinetics confirmed the results obtained with the other two methods used to determine physicochemical stability. In addition, the kinetics indicated that the possibilities of coalescence processes are highly reduced in all cases. It may be concluded that the two type of mixtures remain stable for Seven days at 4 degrees C and 25 degrees C.
