Heparin Preparation

SummaryHeparin samples from five manufacturers were assayed by the revised British Pharmacopoeia (BP) heparin assay and the results compared with those obtained using the activated partial thromboplastin time (APTT) assay. The United States Pharmacopeia (USP) reference heparin preparation and the 4th International Standard (IS) for heparin were also assayed by the two methods relative to the 3rd IS. The results obtained by the revised BP assay were in close agreement with those obtained by the APTT assay for all the heparins that were tested. The assays revealed that there is at least a 10% discrepancy between the International Unit for heparin and the USP unit.

Quantitative Procedure

Abstract The reliability of the currently used quantitative assay for commercially available chlorophyllin copper complex is discussed. It was shown that optical measurements at 405 nm can overestimate the purity of the preparation by 16.4–49.5%. This conclusion is from comparative studies using spectrophotometry at 405 nm and elemental analysis (copper content) of chlorophyllin copper complex. Spectrophotometry at 630 nm resulted in closer agreement with data calculated from elemental analysis. These observations have to be taken into consideration by those involved in the manufacture and distribution of chlorophyllin copper complex as well as in the development of the United States Pharmacopeia compendial monograph for this preparation.
