A comparative bioavailability study was performed using four commercially available, chemically equivalent brands of quinidine sulfate tablets. Two 200-mg tablets were administered to 11 different subjects following a completely randomized crossover design. Serum levels, urinary excretion data, and derived pharmacokinetic parameters were compared(More)
A comparative bioavailability study was performed using two commercially available, chemically equivalent brands of sulfamethizole suspension. One gram of each suspension was administered to 12 different subjects following a completely randomized crossover design. Serum levels and derived pharmacokinetic parameters were compared statistically. There were no(More)
A simple and rapid high-pressure liquid chromatographic method was developed for the determination of sulfadiazine, sulfamerazine, and sulfamethazine in human serum. After the trichloroacetic acid precipitation of the serum proteins, an aliquot of the supernate is injected into a high-pressure liquid chromatograph equipped with a reversed-phase(More)
The dissolution profiles of four commercial quinidine sulfate tablets were determined using the USP rotating-basked dissolution apparatus. Substantial differences in dissolution half-times were noted and compared to previously reported disintegration times, absorption rate constants, and times of appearance of peak serum concentrations.
