CASE 4 William P, a 65-year-old man with obesity (BMI 39 kg/m2) who underwent Roux-en-Y gastric bypass surgery and who has type 2 diabetes, congestive heart failure, coronary artery disease, hypertension, and hyperlipidemia, remains concerned about his weight. He lost 100 lbs following surgery and maintained his weight for 3 years, but then regained 30 lbs. He comes in for an office visit because he’s concerned about his increasing blood sugar and wants to prevent further weight gain. His medications include metformin 1000 mg bid, lisinopril 5 mg/d, carvedilol 12.5 mg bid, simvastatin 20 mg/d, and aspirin 81 mg/d. Laboratory test results are normal except for a hemoglobin A1c of 8%. He denies pancreatitis and a personal or family history of thyroid cancer.
Which medication is an appropriate next step for Mr. P?
Discussion
Pharmacotherapy is a great option for this patient, who is regaining weight following bariatric surgery. Phentermine/topiramate ER is the only medication that would be contraindicated because of his heart disease. Lorcaserin and naltrexone SR/bupropion SR could be considered, but liraglutide 3 mg is the most appropriate option, given his need for further glucose control.
Medication is a great option for patients who are regaining weight after bariatric surgery.
Furthermore, the recent LEADER (Liraglutide effect and action in diabetes: evaluation of CV outcome results) trial reported a significant mortality benefit with liraglutide 1.8 mg/d among patients with type 2 diabetes and high CV risk.47 The study found that liraglutide was superior to placebo in reducing CV events.
Contraindications. Ask patients about a history of pancreatitis before starting liraglutide 3 mg given the possible increased risk. In addition, liraglutide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or in patients with multiple endocrine neoplasia syndrome type 2. Thyroid C-cell tumors have been found in rodents given supratherapeutic doses of liraglutide;48however, there is no evidence of liraglutide causing C-cell tumors in humans.
For patients taking a medication that can cause hypoglycemia, such as insulin or a sulfonylurea, monitor blood sugar and consider reducing the dose of that medication when starting liraglutide.
Administration and titration.Liraglutide is injected subcutaneously once daily. The dose is titrated up weekly to reduce gastrointestinal symptoms.36 The most common adverse effects reported in phase III trials were nausea, diarrhea, and constipation.37-39 Discontinue liraglutide 3 mg if the patient does not lose at least 4% of baseline body weight after 16 weeks.49
