PREPARATION FOR ORAL ADMINISTRATION WITH IMPROVED BIOAVAILABILITY OF MEGESTROL ACETATE, AND METHOD FOR IMPROVING BIOAVAILABILITY OF MEGESTROL ACETATE PREPARATION FOR ORAL ADMINISTRATION

The present invention relates to a preparation for oral administration with improved bioavailability of megestrol acetate, and a method for improving the bioavailability of a megestrol acetate preparation for oral administration. The preparation for oral administration containing megestrol acetate of the present invention shows excellent dissolution rate and bioavailability, and thus equal or superior effects can be obtained compared with a conventional megestrol acetate suspension, even with a much smaller dose. In addition, if prepared into a tablet, it is possible to simultaneously overcome the problem of physical stability of a suspension and to maximize the convenience of drug administration to a patient.
