Fast dissolving tablets (FDTs) of Metformin hydrochloride were developed using the direct compression technique. The formulations incorporated superdisintegrants such as croscarmellose sodium (4%) and sodium starch glycolate (8%). The hardness of formulations F1–F6 ranged from 4.5±0.08 to 3.7±0.10 kg/cm², while disintegration time varied between 61.5±0.54 and 24.5±1.04 seconds. All batches complied with pharmacopeial limits for friability and weight variation.
An increase in superdisintegrant concentration resulted in reduced hardness and faster disintegration. Among all formulations, F6 demonstrated superior performance with the shortest disintegration time (24.5±1.04 seconds), attributed to the effect and mechanism of the superdisintegrants used. In vitro drug release studies showed a release range of 97.40±2.46% to 99.54±1.12%.
Evaluation results indicated that formulations containing natural superdisintegrants exhibited improved hardness, disintegration time, wetting time, and drug release compared to those with synthetic agents. Formulation F6 showed optimal characteristics, including hardness of 3.7±0.10 kg/cm², friability of 0.44±0.01%, wetting time of 17.1±0.76 seconds, dispersion time of 16.3±0.8 seconds, and drug content of 100±1.2%. It achieved maximum drug release (99.54±1.12%) and met all criteria for an effective fast dissolving tablet. Overall, F6 was identified as the best formulation due to its rapid disintegration and wetting, along with adequate mechanical strength.
