[Pharmacokinetics of nitrofurantoin in the bodies of pregnant rats].
The investigation of nitrofurantoin (NTF) pharmacokinetics in pregnant rats was undertaken to estimate its cumulation in the fetus unit. It was found that pharmacokinetics of NTF is dose-dependent in non-pregnant rats. The biological half-life time increased from 0.24 to 0.41 and 0.72 h for NTF doses 10.20 and 40 mg/kg, respectively. The elimination of NTF was diminished in pregnant rats. The pharmacokinetic analysis revealed a possibility of strong NTF accumulation in the pregnant rats (increased K12/K21 ratio). Taking into account increased renal function in pregnancy, one may suspect that decreased elimination of NTF was rather caused by its significant cumulation in the changed tissue compartment.
