Turmeric is a spice derived from the Curcuma longa plant. Dietary supplements and foods containing turmeric are widely promoted for relief of pain and to improve joint mobility, immunity, digestion, cardiovascular health, depression, anxiety, memory, and cognition.

The FDA has approved Genvoya (Gilead), a fixed-dose combination of the integrase strand transfer inhibitor (INSTI) elvitegravir, the pharmacokinetic enhancer cobicistat, and the nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) emtricitabine and tenofovir alafenamide, for treatment of HIV-1 infection in patients ≥12 years old. This is the first approval for tenofovir alafenamide (TAF), a tenofovir prodrug. Stribild, a fixed-dose combination of elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (TDF), was approved in 2012.

The FDA has approved nivolumab (Opdivo – BMS), an IV programmed death receptor-1 (PD-1) blocking antibody, for treatment of unresectable or metastatic melanoma that has progressed following treatment with ipilimumab (and a BRAF inhibitor in patients who are BRAF V600 mutation positive) and for treatment of metastatic squamous non-small cell lung cancer (NSCLC) that has progressed on or after platinum-based chemotherapy. It is the second PD-1 inhibitor to be marketed in the US after pembrolizumab (Keytruda), and the first to be approved for treatment of NSCLC.

FK 506 (Fujisawa), an immunosuppressant similar in activity to cyclosporine (Sandimmune - Medical Letter 25:77, 1983), is currently under investigation in the USA, Europe, and Japan for prevention of organ transplant rejection.

Glatiramer acetate (Copaxone - Teva Marion Partners), formerly known as copolymer-l, has been approved by the US Food and Drug Administration (FDA) for treatment of relapsing-remitting multiple sclerosis (MS). Interferon β-1b (Betaseron) and interferon β-1a (Avonex - Medical Letter, 38:63, 1996) were previously approved for this indication.

The main goals of treatment of chronic obstructive pulmonary disease (COPD) are to relieve symptoms, reduce the frequency and severity of exacerbations, prevent disease progression, and reduce mortality. GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines for treatment of COPD were updated recently. Treatment of acute exacerbations is not discussed here. Drugs available for treatment of COPD are listed in Tables 1 and 3.

Most respiratory tract infections are caused by viruses. Bacterial respiratory tract infections are usually treated empirically with antibiotic therapy that targets the most probable causative pathogens. Recommended antibiotic regimens for outpatient treatment of some common respiratory tract infections are listed in Table 1 for adults and Table 2 for children.

The FDA has approved Nuedexta (Avanir), a fixed-dose combination of the cough suppressant dextromethorphan hydrobromide and the antiarrhythmic quinidine sulfate, for oral treatment of pseudobulbar affect. The combination is the first treatment approved by the FDA for this indication. Studies to support the effectiveness of Nuedexta were performed in patients with underlying amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS); the drug has not been shown to be safe or effective in other types of emotional lability.

The FDA has approved the interleukin-6 (IL-6) receptor antagonist tocilizumab (Actemra – Genentech) for subcutaneous (SC) treatment of giant cell arteritis in adults. It is the first drug to be approved in the US for this indication. Tocilizumab is also approved for treatment of rheumatoid arthritis, polyarticular or systemic juvenile idiopathic arthritis, and cytokine release syndrome.
