Apparent pharmacokinetic parameters of 4-ene VPA and α-fluoro-4-ene VPA in rats

Parameter4-Ene VPA2-aα-F-4-ene VPA2-a

  • 2-a Rats were dosed i.p. with either 4-ene VPA or α-fluoro-4-ene VPA at 1.4 mmol/kg. The data were expressed as mean ± S.D. (N = 4).

  • 2-b The apparent elimination rate constants (K) were estimated from the slopes of the first linear declines in serum drug concentration-time profiles and the half-life (t1/2) calculated as 0.693/K.

  • 2-c The areas under curves (AUC) were estimated using the trapezoidal method and the apparent clearance (CLip) calculated as dose/AUC.
