Abstract
Sodium mercaptoundecahydrododecaborate or BSH is an important compound for boron neutron capture therapy (BNCT). The total clearance and steady state volume of distribution of BSH in humans and in laboratory animals were analyzed as a function of species body weight using the allometric equation for interspecies scaling. Significant linear relationships were obtained between log CLt (Lh-1) and log W (kg) (r = 0.972; p = 0.028) as well as log VSS (L) and log W (kg) (r = 0.999; p = 0.0005). The corresponding allometric equations were CLt = 0.127 W0.68 and VSS = 1.557 W0.87, respectively. BSH clearance in various species was shown to be a constant fraction (0.26) of creatinine clearance, the relationship being independent of body weight. Thus BSH clearance in various species occurred at similar pace when measured by a physiological parameter (creatinine clearance) rather than chronological time. Interspecies scale-up of plasma concentration-time data for the four species using a complex Dedrick plot resulted in similar profiles. Our results indicate that the BSH data obtained in laboratory animals could be utilized to generate preliminary estimates of the pharmacokinetic parameters in humans. These parameters can serve as guidelines for better planning of clinical studies.
