Renal clearance of a recombinant granulocyte colony-stimulating factor, nartograstim, in rats.
    Pharmaceutical research, 1995, Volume: 12, Issue:10

    To clarify the role of the kidney in the elimination of a recombinant human granulocyte colony-stimulating factor, nartograstim, we have investigated its pharmacokinetics in rats with renal failure.. The steady-state clearance (CLss) were determined by the intravenous infusion for 4 hr to unilateral renally-ligated and cisplatin-treated rats, whose renal functions were about 50 and 10% of controls, respectively.. CLss of nartograstim (27 ml/hr/kg) in the renally-ligated rats at a high infusion rate was significantly lower (25%) than in control rats (p < 0.05). CLss in these rats, at a low infusion rate was 95 ml/hr/kg, 14% lower than in control rats. The saturable CLss in these rats, 68 ml/hr/kg, was not significantly different from control rats (75 ml/hr/kg, p > 0.05). Also, CLss in cisplatin-treated rats with extensive renal failure, at a high infusion rate, decreased to 57% of controls. Furthermore, the total body clearances (CLtot) of nartograstim after bolus intravenous administration to renally-ligated and cisplatin-treated rats were reduced to 33-49% of controls.. These results suggest that the kidney may be responsible for 40-50% of the nonsaturable clearance of nartograstim. Thus, the kidney should make a major contribution to the elimination of nartograstim when rats are given a high dose of nartograstim, which saturates the receptor-mediated clearance.
