Abstract

The study was done to evaluate the binding property of different concentrations of Sida acuta gum (SAG) in paracetamol tablet formulations and to compare it to standard gums. SAG was extracted from powdered dried leaves of Sida acuta macerated in distilled water. Paracetamol tablets were prepared by wet granulation using SAG (0 - 2%), Corn starch mucilage (1.5 -2%) and hydroxypropylmethylcellulose, HPMC (1.5 -2%) as binders respectively. They were evaluated based on official and unofficial tests. The paracetamol granules showed passable to excellent flow property. The tablets have hardness values from 3.5 ± 0.00 to 6.75 ± 0.35 Kgf (SAG), 3.75 ± 0.35 to 4.0 ± 1.41 Kgf (starch mucilage), 2.75 ± 0.35 to 3.5 ± 0.00 Kgf (HPMC) and 0.35 Kgf (0 % binder). Tablet friability was less than 1 % for all formulations except P9 (3.18 %) that contained no binder. The % weight deviation for all the formulations ranged from 0.00 to 3.33%. The disintegration time (min) for the tablets ranged from 6.33 ± 5.86 to 49.00 ± 1.00 (SAG), 1.39 ± 0.10 to 1.53 ± 0.13 (Starch mucilage), 0.49 ± 0.08 to 0.79 ± 0.04 (HPMC) and 0.50 ± 0.00 (zero binder). The drug content of the formulations was found to be between 97.2 to 102 %. All the formulations released more than 75 % of their drug contents within 45 min. The binding property of SAG in paracetamol tablet formulations increases with increase in concentration.
