Abstract


Basella alba leaf mucilage was investigated as a binder in paracetamol tablets prepared by wet granulation method. Mucilage at four levels (concentrations of mucilage binders: 4, i.e., 2.5, 5, 7.5 and 10% w/w) were studied. No significant work has been reported to use it as a tablet binder. The evaluation of granules showed 0.62 to 0.76 mm granule size, 28°47' to 30°27' angle of repose and 31.57 to 23.45% fines. Moisture content of the different granulations was less than 1%. The tablets were prepared and evaluated for average weight and weight variation, thickness, content uniformity, hardness, friability, disintegration time and in vitro dissolution profiles. All the batches of tablets exhibited good uniformity in content. The hardness was within the range of 4.5 to 5.5 kg/cm2. The hardness was increased and friability decreased with the increasing concentration of binding agent. The disintegration time also increased with increasing binder concentrations. The evaluation of tablet showed 0.434 to 0.410% friability, 9 to 18 minutes disintegration time
and the drug release was more than 70% in 60 minutes. Tablets at 7.5% w/w binder concentration showed more optimum results as tablet binder. The B. alba mucilage was found to be good as a binder to paracetamol tablets.
Key words: Basella alba, binder, mucilage, paracetamol, patchaippasali
