title: [Evaluation of the bioavailability of Polfa phenytoin tablets].
abstract: Bioavailability of Phenytoin "Polfa" tablets was studied in comparison with Epanutin "Parke-Davis" capsules. It was found that the relative degree of bioavailability of Phenytoin in relation to Epanutin as a standard is 70,7 +/- 6,3% (SD). The cause of worse bioavailability of Phenytoin "Polfa" are differences in pharmaceutical forms of both preparations. The necessity to increase an average dose of Phenytoin "Polfa" tablets is suggested to gain optimal concentration of diphenyl-hydantoin in serum, in therapeutic range.
