Comparative Study
Tissue storage of 14C-labelled hydroxyethyl starch (HES) 130/0.4 and HES 200/0.5 after repeated intravenous administration to rats.
To investigate the effect of the molar substitution of hydroxyethyl starch (HES) solutions on tissue and organ storage in rats after repeated administration. ⋯ Tissue storage after repeated administration of an HES solution with a low molar substitution (0.4) was significantly lower in the total body as well as in the liver and carcass compared with an HES solution with a medium molar substitution (0.5). However, the potential clinical consequences of these present findings have not yet been determined.

Troxacitabine [BCH 4556; SPD 758; Troxatyl] is a DNA synthesis inhibitor. This profile has been selected from R&D Insight, a pharmaceutical intelligence database produced by Adis International Ltd. It is a member of a novel class of nucleoside analogues discovered by BioChem Pharma and is the first example of a synthetic L-nucleoside analogue to have shown anticancer activity in animal models. ⋯ The aim is to identify the most promising treatment regimens in a relatively small number of patients before commencing the larger pivotal trial. A pivotal phase III trial is expected to begin in the first half of 2003. In September 2002, Shire Pharmaceuticals forecast Troxatyl to reach peak sales of $US100-200 million, for the indications of pancreatic cancer and myeloid leukaemia.
