Adults with a body mass index (BMI) between 25 and 29.9 kg/m2 are considered overweight. Those with a BMI ≥30 are considered obese. The initial recommendation for any weight loss effort is to achieve a 5-10% reduction in weight, which has been associated with a reduction in the risk of developing type 2 diabetes, hypertension, and dyslipidemia. Diet, exercise, and behavior modification are the preferred methods for losing weight, but long-term weight maintenance can be difficult. Several drugs and devices are FDA-approved for weight reduction and maintenance of weight...

The FDA has approved osilodrostat (Isturisa – Recordati), a cortisol synthesis inhibitor, for oral treatment of adults with Cushing's disease when surgical resection of the pituitary adenoma is not an option or has not been curative. Osilodrostat is the first cortisol synthesis inhibitor to be approved in the US for this indication. Other oral steroidogenesis inhibitors such as ketoconazole and metyrapone have been used off-label for this indication for many years.

The FDA has approved Combogesic IV (Hikma), an IV solution containing acetaminophen and ibuprofen, to treat mild to moderate pain (alone) or moderate to severe pain (in combination with an opioid) in adults when IV analgesia is considered clinically necessary. Single-drug IV solutions containing ibuprofen (Caldolor) and acetaminophen have been available in the US for years.

A selective serotonin reuptake inhibitor (SSRI) is generally used for initial treatment of major depressive disorder (MDD). A serotonin-norepinephrine reuptake inhibitor (SNRI), bupropion (Wellbutrin SR, and others), and mirtazapine (Remeron, and others) are reasonable alternatives. Improvement in symptoms can occur within the first two weeks of treatment with these drugs, but a substantial benefit may not be achieved for 4-8 weeks.

The motor symptoms of Parkinson's disease (PD) are caused primarily by degeneration of dopaminergic neurons in the substantia nigra. The nonmotor symptoms of the disease are thought to be caused by degeneration of other neurotransmitter systems. No disease-modifying drugs are available for treatment of PD.

Most patients with multiple sclerosis (MS) present with the relapsing-remitting form of the disease. Pharmacologic treatment usually includes a disease-modifying drug, corticosteroids for acute exacerbations, and other drugs for managing symptoms such as fatigue, depression, and pain. Early use of disease-modifying therapy has improved clinical outcomes.

The tissue plasminogen activator (tPA) tenecteplase (TNKase – Genentech) has been approved by the FDA for treatment of acute ischemic stroke in adults. It is the second tPA to be approved in the US for this indication; alteplase (Activase) was approved in 1996. Tenecteplase was approved in 2000 to reduce the risk of death associated with acute ST-elevation myocardial infarction (STEMI).
