The US Department of Health and Human Services, in conjunction with the US Department of Agriculture, has released the latest update of its Dietary Guidelines (www.health.gov). The emphasis this time is on weight loss through calorie restriction and exercise. A low-fat intake is recommended; a low-carbohydrate diet is not. Fruits, vegetables and whole grains are encouraged. A review of Diet, Drugs and Surgery for Weight Loss appeared in the December 2003 issue of Treatment Guidelines from The Medical Letter.

Nearly 30 years after the first publication of Dr. Atkins' Diet Revolution promoting a high-protein, extremely low-carbohydrate diet, patients once again are asking their physicians about the Atkins diet.

Some readers have objected to our recommendation (Med Lett Drugs Ther 2013; 55:55) that postmenopausal women with an intact uterus who take the oral estrogen agonist/antagonist ospemifene (Osphena) to reduce the severity of dyspareunia should also take a progestin.1 Ospemifene has agonistic effects on the endometrium, and the Osphena package insert says: "Generally, when a product with estrogen agonistic effects on the endometrium is prescribed for a postmenopausal woman with a uterus, a progestin should be considered to reduce the risk of endometrial cancer."Endometrial hyperplasia has been...

Empagliflozin (Jardiance – Boehringer Ingelheim/Lilly), an SGLT2 inhibitor, has been approved by the FDA for oral treatment of type 2 diabetes. It is the third SGLT2 inhibitor to be approved for this indication.

The FDA has approved diazoxide choline extended-release tablets (Vykat XR – Soleno Therapeutics) for treatment of hyperphagia in patients ≥4 years old with Prader-Willi syndrome. Diazoxide choline is the first drug to be approved in the US for this indication. Diazoxide oral suspension (Proglycem) has been available for years for management of symptomatic hypoglycemia.

The FDA has approved a new tablet formulation of bromocriptine mesylate (Cycloset – VeroScience) for treatment of type 2 diabetes in adults. Bromocriptine (Parlodel, and others) is an ergot-derived dopamine agonist that has been used for more than 20 years to treat hyperprolactinemia, acromegaly, Parkinson’s disease and restless leg syndrome.

Trofinetide (Daybue – Acadia), a synthetic analog of glycine-proline-glutamate, has been approved by the FDA for treatment of Rett syndrome in patients ≥2 years old. It is the first drug to be approved in the US for treatment of Rett syndrome.

The FDA has approved viloxazine extended-release capsules (Qelbree – Supernus) for treatment of attention-deficit/hyperactivity disorder (ADHD) in children 6-17 years old. Viloxazine is the second selective norepinephrine reuptake inhibitor to be approved in the US for treatment of ADHD; atomoxetine (Strattera, and generics) was approved in 2002.

Diet, exercise, and weight loss can improve glycemic control, but almost all patients with type 2 diabetes require antihyperglycemic drug therapy. Treating to a target A1C of <7% while minimizing hypoglycemia is recommended to prevent microvascular complications of diabetes (retinopathy, nephropathy, and neuropathy). An A1C target of <8% may be appropriate for some older patients.

The FDA recently expanded the eligibility criteria (see Table 1) for treatment with the surgically implanted hypoglossal nerve stimulation system (Inspire Upper Airway Stimulation – Inspire Medical Systems). The device has been advertised lately on radio and television.
