Oral hypoglycemic drugs used for diabetes mellitus mnemonic: Metformin meets glucose and advises it to stay out of the blood. It asks the liver to keep glucose in the house (Inhibits hepatic glucose production) and asks the glucose in the bloodstream to go into adipose and skeletal muscle (Stimulates peripheral uptake of glucose). Metformin never met a glucose molecule and did not tell him to not stay in the blood (Illustration in the original post).
