* Indications: DMT2 * MOA: decreases hepatic glucose production and to a lesser extent enhances insulin sensitivity in skeletal muscle * SE: when used alone generally does not cause hypoglycemia; can cause modest wt reduction in pts taking; MC SEs are abd cramping and nausea; metallic taste; most serious SE is development of lactic acidosis which can be fatal (don’t use in pts w/impaired renal fxn as this can cause lactic acidosis) * Need to supplement with B12 or B complex when on

Answer 79

• Indications: DMT2 • MOA: stimulate intact beta cells of the pancreas to release more insulin – occurs as a result of interaction of a sulfonylurea w/the ATP sensitive K+ channels in the beta cell membrane, by partially blocking K+ channels the time the beta cell spends in the Ca2+ release stage is increased which means more insulin release • SE: most concerning SE is hypoglycemia, particularly in pts w/impaired renal or hepatic fxn; wt gain; total beta cell fxn generally declines with prolonged use (will need to switch after 5-10 years of use) • Cause fetal hypoxemia as a direct result of hyper-insulinemia (causes increased extraction of O2 from fetal blood supply by baby and this exceeds the placenta’s ability to supply O2= fetal hypoxemia) • DO NOT GIVE TO PTS W/SULFA ALLERGY o Gyburide, Gimepiride, Glipizide • Will be ineffective in pts where there is an absolute deficiency of insulin production such as in DMT1 pts or post-pancreatectomy

Answer 80

* Indications: DMT2 * MOA: stimulate beta cells to release insulin (non-sulfonylurea secretagogues); closes K+ channels on beta cell plasma membranes = more insulin release * SE: wt gain, hypoglycemia, have to take with meals = frequent dosing * Repaglinide is most efficacious in achieving blood glucose control and lowering HgA1c levels
