EP is a 38-year-old female patient that comes in for diabetes education and
management. She was diagnosed 12 years ago and states lately she is not able
... [Show More] to
control her diet although she continues a 1600 calorie diet with appropriate daily
carbohydrate intake (per dietitian prescription) and walks 40 minutes every day of the
week. She states compliance with all medications. She denies any history of
hypoglycemia despite being able to identify signs and symptoms and describe
appropriate treatment strategies.
PMH: T2DM, HTN, obesity, depression, s/p thyroidectomy due to thyroid cancer
FmHx: Noncontributory
SHx: (−) Smoking, alcohol use, past marijuana use while in high school
Medications: Metformin 850 mg tid, glipizide 20 mg bid, lisinopril 20 mg daily, sertraline
100 mg daily, multivitamin daily
Vitals: BP 128/82 mg Hg; P 72 beats/min; BMI 31 m/kg2
Laboratory test results: Na 134 mEq/L, K 5.4 mEq/L, Cl 106 mEq/L, BUN 16 mg/dL, SCr

Based on EP's profile above, which of the agents would be able to obtain an A1C goal
of less than 7% and would be appropriate in the patient? Please provide an explanation
of appropriateness or lack thereof. - ANS-Exenatide - Exenatide (Bydureon) once
weekly has been able to demonstrate weight loss and decrease A1C% by 0.7% to 1.2%
in clinical trials; however it is contraindicated for EP due to the self-reported history of
thyroid cancer.
Dapagliflozin - Dapagliflozin (Farxiga) is contraindicated in this patient due to
hyperkalemia which could be made worse by this drug. The package insert does not
indicate a specific potassium concentration cut off to no longer use this medication;
however, there are better choices in this patient.
Sitagliptin - Sitagliptin (Januvia) is able to obtain an A1C goal of less than 7% based on
clinical trials and currently the patient does not have any cautionary objective measures
to not use this medication. DPP-IV inhibitors are weight neutral. DPP-IV inhibitors can
be used in patients taking sulfonylureas; however, it may be recommended to reduce or
stop the sulfonylurea dose.
Acarbose - Acarbose (Precose) is not recommended for initial management and is
associated with significant GI side effects. More information would be needed regarding
fasting and post-prandial numbers. In addition, adding acarbose would only lower A1c
by 0.8% at best and therefore would not achieve the desired A1C goal of <7%
