Title: Metformin estraction
Post by: davideroma94 on June 14, 2020, 02:12:25 PM

Hello everyone! I would like to extract a "pure powder" of metformin starting from metformin tablets or water-soluble solution.
Is there a way to do that, removing the excipients?


EXCIPIENT LIST

Soluble metformin: "Acesulfame potassium, Aspartame (E951) Anhydrous citric acid Erythritol, Pullulan corn starch PI-20"

Metformin tablets: "Each film-coated tablet contains: Colloidal anhydrous silica, povidone, macrogol 4000, magnesium stearate, Opadry II 85F29116 clear (polyvinyl alcohol, macrogol 3350, talc)."
