Procedure

Metformin hydrochloride is screened through a 1 mm sieve. Screened metformin hydrochloride is granulated in a fluid bed granulator with a solution of povidone in demineralized water and dried in the same device. Dried granulate is screened through a 1 mm sieve. The obtained granulate, microcrystalline cellulose and ethylcellulose are homogenously blended in a bin blender. Pre-sieved magnesium stearate is added to the obtained blend and blended in bin blender so that the final blend is obtained. The final blend is compressed into a bilayer tablet as disclosed in Examples 16 and 17.
