Attempt has been made to develop controlled release tablets of Oxymorphone by using xanthan gum, karaya gum, guar gum aspolymers.Nine formulations were prepared by taking different concentrations of polymers.All the formulations were prepared by direct compression method using 6mm punch on 8 station rotary tablet punching machine. The blend of all the formulations showed good flow properties such as angle of repose, bulk density, tapped density. The prepared tablets were shown good post compression parameters and they passed all the quality control evaluation parameters as per I.P limits Compared to all formulations F3 formulation showed maximum % drug release i.e., 98.56 % in 12 hours hence it is considered as optimized formulation.
Keywords: Oxymorphone, xanthan gum, karaya gum, guar gum.
