For controlling the release of Ketoprofen from matrix tablets, combinations
between different polymers in different ratio were formulated.
Aim: The aim of this study is to investigate the applicability of HPMC combination with
Polymethacrylates (Eُudragit RS, RL & L100) for controlling the release of ketoprofen from matrix
tablets. Four types of HPMC with different viscosities were tested in the study.
