The binder gum is natural and have pH between
7.3 -7.7. The prepared granules were evaluated for
percentage of fines, particle size and flow properties. It
was observed when the concentration of binder was
increased, the percentage of fines was reduced. The
flow property of granules was determined by angle of
repose and it was found that values were between
30.11 to 33.54°. All batches showed good flow
property.
Three batches of tablets of each binder
concentration were prepared. The prepared tablets
were evaluated for content uniformity, hardness,
friability and disintegration time. The results are
indicated in Table 3. All batches of tablets exhibited a
good uniformity in content. The tablet hardness and
disintegration time increased with increase in binder
concentration. The friability values decreased with
increase in binder concentration. All the evaluation
parameters were found to be within the
pharmacopoeial limits at binder concentrations 2.5-7.5
% w/w.
