Reference no: EM131062091

Metformin is used to treat Type II Diabetes. It is excreted in the urine with no metabolism from the liver with a half-life of 5 hours. Average Volume of Distribution of Metformin is 654 L for a dose of 850 mg. If the plasma concentration of the drug needs to be at least 200 µg / L, how many times a day would an 850 mg dose need to be taken to maintain this concentration?
