Purpose: To investigate the binding properties of the modified (acid treated) millet (Pennisetum glaucum) starch mucilage in comparison with maize starch BP on some physical characteristics of paracetamol tablets.

Method: Pennisetum glaucumstarch was extracted and subjected to acid modification. Mucilages of the modified starch and maize starch BP was used to prepare paracetamol granules and tablets by wet granulation method at various concentrations. The granules were characterized for their flow properties while the tablets were characterized for their tablet parameters. In vitro drug release and FTIR compatibility studies was carried out on the tablet formulation.

Result: The starch extraction and modification processes gave a percentage yield of 53.65 and 58.74 % respectively. Prepared granules were free flowing with Carr’s indices, Hausner’s ratios and angles of repose of ≤15%, ≤1.2 and <31°, respectively. At all binder concentrations, the tablets showed satisfactory hardness(5.15-7.75 kp), friability values (< 1.0 %) and disintegration times(<15 min).The dissolution studies showed that all batches achieved over 70 % drug release in 30 min while the compatibility study revealed no interaction between paracetamol and the modified starch.

Conclusion: The results from the study shows that modified millet starch when used as a binder in paracetamol tablets exhibited comparable granule and tablet properties with maize starch BP.
