Abstract
The release profile of indomethacin (IM) from a direct compressible matrix containing three hydrophilic cellulose derivatives, methylcellulose (MC25 and MC50), hydroxypropylcellulose (HPC140), and hydroxypropylmethylcellulose (HPMC50) was studied. The drug release profile vas affected by matrix size, polymer type, drug:polymer ratio and water soluble additive (lactose). An IM zero-order release matrix can be obtained by mixture and direct compression with MC50, HPMC50 and HPC140. The release rate from the MC50 and HPC140 matrix can be modified by replacing MC50 or HPC140 with MC25, and a zero-order release could be obtained even when the amount of replacement with MC25 is up to 35 and 45%, respectively. Lactose up to 10% slightly affected the release profile. IM released from this kind of matrix by a zero-order rate seems to be controlled by the swelling and relaxation of the polymer.
