Effect of liquid diet on serum protein binding and prednisolone concentrations after oral prednisone.

After prednisone (two 5 mg tablets) was given to each of six normal volunteers with water or with a liquid meal, standard pharmacokinetic parameters of prednisolone metabolism were similar, except that peak serum prednisolone concentrations occurred later after the meal. We conclude that prednisone can be given with a meal without significantly affecting the metabolism of prednisone or prednisolone.
