Median lethal doses were estimated for PGBx administered to mice by the intraperitoneal and intravenous routes. The incidence of lethality (and therefore the LD50) was time dependent over a 96 hour period. The animals were active, were responsive and took nourishment during the 4-day post-injection period so that they apparently died from the direct effects of PGBx (or its metabolites) and not as a consequence of depression-induced dehydration or starvation.
