Metformin Hydrochloride (herein referred to as metformin HCl) that may be 98.5%-100% pure is a high dose drug capable of being directly compressed with specific excipients into tablets having desired, hardness, disintegrating ability, and acceptable dissolution characteristics. Metformin HCl is not inherently compressible and thus presents formulation problems. Excipients used in the formulation enhance the flow and compaction properties of the drug and tableting mix. Optimal flow contributes to uniform die fill and weight control. The binder used ensures sufficient cohesive properties that allow metformin HCl to be compressed using the direct compression method. The tablets produced provide an acceptable in-vitro dissolution profile.
