[Correlations between the pharmacokinetic indices of the tranquilizer fenazepam in single and long-term administration to patients].

A high degree of correlation between experimentally established and theoretically calculated constant concentrations of phenazepam was revealed in blood plasma of patients. Due to experimental findings the employment of a single-dose drug administration with regard to previously stated effective-dose interval during dosage build-up made possible estimating the maximum allowable individual dosage which should yield a good therapeutic result without side effects.
