Burst Drug Release Compositions
A solid dose composition comprising at least one pharmaceutically active ingredient and at least one controlled release agent and method of manufacturing said composition is disclosed. The burst profile of at least one pharmaceutically active ingredient in the composition is regulated by the apparent viscosity of the controlled release agent and wherein at least one pharmaceutically active ingredient is processed by wet granulation.
1 . A solid dose composition comprising at least one pharmaceutically active ingredient and at least one controlled release agent wherein the burst profile of at least one pharmaceutically active ingredient is regulated by the apparent viscosity of the controlled release agent and wherein at least one pharmaceutically active ingredient is processed by wet granulation.
2 . A method of manufacturing a solid dose composition comprising at least one pharmaceutically active ingredient and at least one controlled release agent wherein the burst profile of at least one pharmaceutically active ingredient is regulated by the apparent viscosity of the controlled release agent and wherein at least one pharmaceutically active ingredient is processed by wet granulation.
3 . A solid dose composition comprising at least one pharmaceutically active ingredient and at least one controlled release agent wherein the apparent viscosity of the controlled release agent is between 100 and 100,000 centipoise and wherein at least one pharmaceutically active ingredient is processed by wet granulation.
4 . A solid dose composition of claim 3 wherein at least one of the pharmaceutically active ingredients is ibuprofen.
5 . A solid dose composition of claim 3 wherein at least one of the controlled release agents is hydroxypropylmethylcellulose.
6 . A solid dose composition of claim 3 wherein at least one of the controlled release agents is hydroxypropylmethylcellulose and wherein at least one of the pharmaceutically active ingredients is ibuprofen.
7 . A method of manufacturing a solid dose composition of claim 2 wherein at least one of the pharmaceutically active ingredients is ibuprofen.
8 . A method of manufacturing a solid dose composition of claim 2 wherein at least one of the controlled release agents is hydroxypropylmethylcellulose.
9 . A method of manufacturing a solid dose composition of claim 2 wherein at least one of the controlled release agents is hydroxypropylmethylcellulose and wherein at least one of the pharmaceutically active ingredients is ibuprofen.
