ABSTRACT:
Aim: The current paper was an attempt to design a extended release dosage form of Metformin hydrochloride using various grades of hydrophilic polymers, hydroxy propyl methyl cellulose (HPMC K4M, HPMC K15M, HPMC K100M and HPMC K200M) and MCC.
Materials and Methods: Laboratory scale batches of 4 tablet formulations were prepared by wet granulation technique. Precompression parameters of the granules were evaluated prior to compression. Tablets were characterized as crushing strength, friability, weight variation, thickness, drug content or assay and evaluated for in-vitro release pattern for 12 hr using Phosphate buffer of pH 6.8 at 37 ± 0.5°C.
Results and Discussion: The results obtained revealed that HPMC K100M in formulation (F3) was able to sustain the drug release for 12 h and followed the Higuchi pattern quasi-Fickian diffusion. and charged for stability testing, parameters were within the limit of acceptance. There was no chemical interaction found between the drug and excipients during Fourier Transform Infrared Spectroscopy (FTIR).
Conclusion: Hence it can be concluded that formulation F3 containing HPMC K100M is suitable for development of extended release tablets of Metformin Hydrochloride.
