A patient concurrently taking a beta-blocker. What does the patient need to be aware of?
a) beta blockers increase glycogenolysis and help the body react to low glucose

Which is not a side effect of metformin ( select all that apply)?
a) GI upset
b) hypoglycemia
c) medullary thyroid cancer
d) lactic acidosis
Answer: b & c
Medullary thyroid cancer is associated with Exenatide (a GLP-1 receptor agonist)
Which patient comorbidities place the patient at high risk for lactic acidosis while taking metformin?
a) CHF
b) CKD
c) cirrhosis
d) hypothyroid
Answer: a &b
Lactic acidosis is especially concerning in patients with CKG/CHF
True or false, patients should take metformin on an empty stomach.
False, they should take with food to minimize GI upset.
The ER version also has less GI effects.
Which of the following is NOT a MOA for metformin?
a) blocks the ATP/K channel which causes membrane depolarization
b) inhibits glucose production in liver
c) confers resistance to DPP-4 inactivation of GLP-1 in the gut
d) reduces glucose absorption in gut
e) sensitizes insulin receptors in target tissue
Answer: a & c
Metformin works by inhibiting glucose production by the liver; reduces glucose absorption from gut; sensitizes insulin receptors in target tissue; increases glucose uptake in response to available insulin
Which drug does not cause weight gain?
a) meglitinides
b) metformin
c) sulfonyureas
