Evolocumab (Repatha – Amgen), a subcutaneously injected PCSK9 inhibitor, has been approved by the FDA as an adjunct to diet and maximally tolerated statin therapy for adults with heterozygous familial hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease who require additional lowering of LDL-cholesterol (LDL-C). It was also approved as an adjunct to diet and other LDL-lowering therapies in patients with homozygous familial hypercholesterolemia (HoFH) who require additional lowering of LDL-C. Evolocumab is the second PCSK9 inhibitor to be approved in the...

The antiplatelet drug clopidogrel (Plavix, and others) reduces major cardiovascular events, but can cause bleeding. Proton pump inhibitors (PPIs) are often used with clopidogrel to prevent gastrointestinal bleeding, however, some evidence suggests that PPIs may interfere with the activation of clopidogrel and diminish its antiplatelet effect. FDA-approved labeling recommends avoiding concurrent use of the PPIs omeprazole and esomeprazole with clopidogrel.

The FDA has approved a subcutaneously administered 20% solution of human immune globulin (Cuvitru – Shire) for replacement therapy in patients ≥2 years old with a primary humoral immunodeficiency. Hizentra (CSL Behring), another subcutaneously administered 20% immune globulin solution, was approved in 2010 for the same indication. The IgG component of Cuvitru is similar to that of Gammagard Liquid and HyQvia, two subcutaneously administered 10% immune globulin formulations also manufactured by Shire and approved for treatment of primary...

The FDA has approved fostamatinib disodium hexahydrate (Tavalisse – Rigel), the first spleen tyrosine kinase (SYK) inhibitor, for oral treatment of thrombocytopenia in adults with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment.

The FDA has approved Duaklir Pressair (Circassia), a fixed-dose combination of the long-acting muscarinic antagonist (LAMA) aclidinium bromide and the longacting beta₂-adrenergic agonist (LABA) formoterol fumarate, for maintenance treatment of chronic obstructive pulmonary disease (COPD). Aclidinium/formoterol is the fifth LAMA/LABA combination to be approved in the US for this indication.

The FDA has approved peanut allergen powder-dnfp (Palforzia – Aimmune) for use as oral immunotherapy to mitigate allergic reactions, including anaphylaxis, caused by accidental peanut exposure in patients with a confirmed peanut allergy. It is the first drug to be approved in the US for this indication; Viaskin Peanut, an immunotherapy patch, is under FDA review for the same indication.

The centuries-old anti-inflammatory drug colchicine (Colcrys, and others) is FDA-approved for prophylaxis and treatment of gout flares and for treatment of familial Mediterranean fever. It is also used off-label to treat pericarditis, and in recent years has been investigated for reduction of cardiovascular risk in patients with coronary artery disease (CAD).

The injectable glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide (Ozempic – Novo Nordisk) has been approved by the FDA to reduce the risk of sustained eGFR decline, end-stage kidney disease, and cardiovascular death in adults with type 2 diabetes and chronic kidney disease (CKD). It is the first GLP-1 receptor agonist to be approved in the US for this indication.

Atopic dermatitis (AD; also known as eczema) is frequently associated with other atopic disorders such as allergic rhinitis, asthma, and food allergy. It commonly presents in infancy and early childhood and has a relapsing course, often improving by adolescence, but sometimes persisting into (or first appearing in) adulthood or even old age.

The tables in this article list drugs used for treatment of cancer in the USA and Canada and their major adverse effects. The choice of drugs in Table I is based on the opinions of Medical Letter consultants. Some drugs are listed for indications for which they have not been approved by the US Food and Drug Administration. In some cases, such as elderly patients or those with many co-morbid illnesses, the regimen of choice might not be suitable. For many of the cancers listed, surgery and/or radiation therapy may be the treatment of choice or may also be part of the management. Anticancer...
