Abstract
AIM: To investigate the bioequivalence between capsules and tablets of complex chlorzoxazone in healthy volunteers.METHODS:twenty volunteers were randomly divided into two groups(test and reference),ten in each,with crossover design.The concentration of complex chlorzoxazone was determined by HPLC and pharmacokinetic parameters were calculated with DAS(2.0) practical pharmacokinetics program.RESULTS:The relative bioavalibility of chlorzoxazone and acetaminophen in complex chlorzoxazone capsules were((109.1)±(30.9))% and((114.0)±(50.5))%,respectively.CONCLUSION: The statistical analysis showed that the test and reference preparation were bioequivalent.
