Plasma concentrations and pharmacokinetics of misonidazole after intraperitoneal administration to the mouse.

The pharmacokinetics of misonidazole, a hypoxic-cell radiosensitizer, were determinated after intraperitoneal administration to standardized Balb/c mice. The experimental data was fitted, using non linear analysis, to plasma-concentration curves described by tri-exponential equations derived from a two-compartment model. The pharmacokinetic constants (absorption and elimination coefficients) were determinated.
