Etymology: Metformin is a coined pharmaceutical name, built from two pieces that point back to an older drug. Its first part, "meth-", comes from the methyl group in its chemical structure, and its second part, "-formin", is a shortened form of the name of phenformin, the earlier biguanide drug it was derived from. The name was constructed to signal a family resemblance to that predecessor rather than to describe any everyday meaning. The ending matters more than the beginning. Phenformin was developed in the same chemical family, and it was withdrawn in many countries because it carried a risk of lactic acidosis, a dangerous buildup of acid in the blood. Metformin is a close chemical relative that was judged to be far safer, so its name carries the family marker while the drug itself replaced its troubled predecessor.

Synonyms: glucophage
