Procedure
Metformin hydrochloride is screened through a 1 mm sieve. Screened metformin hydrochloride is granulated in fluid bed granulator with the solution of povidone in demineralized water and dried in the same device. The dried granulate is screened through a 1 mm sieve. The obtained granulate, microcrystalline cellulose and hydrogenated castor oil are homogenously blended in a bin blender. Pre-sieved magnesium stearate is added to the obtained blend and blended in a bin blender so that the final blend is obtained. The final blend is compressed into a bilayer tablet as disclosed in Examples 14 and 15.
