title: [Evaluation of the biological availability of 2 carbamazepine preparations].
abstract: The biological availability was determined of two carbamazepine preparations: Amizepin POLFA and Tegretol GEIGY in tablets. The study was carried out in 10 patients giving them the drug in doses of 400 mg by the crossover method at an interval of 3 weeks. The statistical analysis of the mean maximal values, mean times of reaching of maximal concentrations, and mean areas under the curve of serum carbamazepine concentration changes for both forms of the drug showed a comparable biological availability of Amizepin and Tegretol. The relative degree of bioavailability of Amizepin amounted to 98% of that of Tegretol. The values of pharmacokinetic parameters of both drugs were compared. The value of distribution volume was greater in the case of Tegretol, and the difference was statistically significant. No significant differences were found between the remaining calculated parameters.
