The results of two randomized, single-dose, crossover bioavailability studies are presented which describe the pharmacokinetics and oral bioavailability of nevirapine, a novel nonnucleoside antiretroviral drug. In the first study 12 healthy male volunteers received nevirapine 15 mg via short-term i.

โฆ Synopsis
A single dose of 8 mg of thiocolchicoside was administered to 12 healthy volunteers according to a Latin square design, either as tablets (reference), oral solution, or intramuscular injection. Serum thiocolchicoside concentrations showed an absorption phase followed by a biexponential decay with a terminal half-life (f1,2@) of approximately 5 h, similar for the three formulations. The relative bioavailability of both oral formulations was approximately 25%, compared to the intramuscular formulation.
There was a trend for the oral solution to have a slightly larger AUC and C,, , as well as a slightly shorter T,, , than the tablet formulation. However, the comparison of the two oral forms did not show statistically significant differences in the pharmacokinetic parameters C,,, T,,, and AUC, suggesting that the Coltramyl@ tablets have an adequate in vivo dissolution profile.
