ABSTRACT
The aim of present study was to formulate and evaluate probiotic
tablets containing anti-inflammatory drug Mesalazine. Matrix tablets
were prepared using Sodium alginate and
Hydroxypropylmethylcellulose acetate succinate (HPMCAS) as
matrix forming components, with three different combinations by wet
granulation method. The granules were evaluated for angle of repose,
bulk density, tapped density, compressibility index and Hausners
ratio. The tablets were subjected to weight variation, hardness,
friability and drug content test and invitro release studies.
Additionally the tablets were tested for contents of viable cell counts
of probiotic lactobacilli using standard plate count (SPC) method.
Invitro release studies revealed that all formulations qualified both
stages for release of the drug i.e. acid stage and buffer stage 1. The
release profiles were affected by variable concentrations of sodium
alginate when combined with HPMC-AS. The combination at 1:2 (SA2) prevented the
escape of both actives more effectively than the other two formulations at all the three stages
of dissolution test. A few numbers of bacterial cells were lost in acid stage as well as in the
subsequent buffer stage1. However, at the end of buffer stage 2 the viable cell count for
Lactobacillus plantarum, were found to be 7 × 109 CFU. The combinations of HPMCAS
(HF) and sodium alginate together increased acid tolerance of probiotic lactobacilli strain
added in matrix tablets.
