[Study of sustained-matrix tablets Ambroxol hydrochloride and potential impact of different fillers on the matrix tablet's scale-up].
Beijing Da Xue Xue Bao Yi Xue Ban. 2012 Oct 18; 44(5):742-8.BD

Abstract

OBJECTIVE

To study the release profiles of Ambroxol hydrochloride in matrix tablets with different fillers and controlled release materials, and investigate the potential impact on different fillers on the matrix tablet's scale-up.

METHODS

Ambroxol hydrochloride was chosen as the model drug to make single-layer matrix tablets with different types of hydroxylpropyl methylcellulose as matrix material, and lactose or microcrystalline cellulose as the filler. In vitro dissolution test was used to evaluate the drug release performance of the matrix tablets made. Also ethyl cellulose was used to prepare double-layer matrix tablets to investigate how different kinds of hydroxypropyl methylcellulose (HPMC) and fillers would affect the drug release in double-layer matrix tablets.

RESULTS

The drug release rate of single-layer tablets with lactose and HPMC decreased significantly with the increase of the level and viscosity of HPMC. However the release profile only slightly slowed down with the increase of the content and viscosity of HPMC for single-layer matrix tablets of microcrystalline cellulose (MCC). Compared with the single-layer tablets, the level and viscosity of HPMC had less impact on the drug release of the double-layer matrix tablets.

CONCLUSION

The matrix tablet with lactose and HPMC has greater flexibility to design formulations with different drug release rate, however the introduction of other process parameters during the scale-up could lead the shifting of the drug release profile from small scale batches. The drug release profiles of matrix tablets with insoluble filler-MCC only change within a small range with the increase of the level and viscosity of HPMC. From the formulation design point of view, it could be necessary to select different type of controlled release polymers to meet the design requirement.
