In recent years a number of decision rules, based on sound statistical principles, have been proposed for deciding if a test formulation is bioequivalent to a reference formulation. The decision rule based on confidence intervals has been accepted by regulatory agencies, at least by the Food and Drug Administration of the United States. A useful property of… (More)
Insomnia and anxiety decreased in 12 outpatients taking triazolam following alcohol withdrawal.
Eleven healthy subjects received single oral doses of placebo, 2 mg diazepam, 5 mg diazepam, and 10 mg diazepam in a randomized four-way crossover study. Plasma diazepam levels, the Digit Symbol Substitution Test (DSST), and fraction of total electroencephalographic (EEG) amplitude falling in the sigma plus beta (13 to 31 Hz) frequency range were determined… (More)
An important part of pharmacokinetic research is fitting models to observed data and estimating the parameters in the model. In general, parameter estimation in pharmacokinetics is a subset of the general problem of nonlinear regression or parameter estimation in nonlinear regression models. The same criteria, algorithms, and software used in other areas of… (More)
The effects of a fish oil supplement on lipid and lipoprotein levels, platelet function, and vital signs were investigated in 31 hypercholesterolemic patients. Thirteen patients took 5 g of encapsulated fish oil per day and 18 patients took 5 g of encapsulated safflower oil "placebo" per day for 28 days. Diet and exercise patterns were kept as constant as… (More)
This paper presents the deterministic and stochastic model for a linear compartment system with constant coefficients, and it develops expressions for the mean residence times (MRT) and the variances of the residence times (VRT) for the stochastic model. The expressions are relatively simple computationally, involving primarily matrix inversion, and they… (More)
