Opioids, benzodiazepines, propofol, antipsychotics and dexmedetomidine (Precedex) are frequently used in the intensive care unit (ICU) to manage pain, anxiety, agitation and delirium, and to facilitate procedures such as mechanical ventilation. The use of dexmedetomidine, a centrally-acting selective α₂-receptor agonist approved by the FDA in 1999, has been increasing in recent years. Some new studies comparing it to other drugs for ICU sedation have been published.

The FDA has approved fidaxomicin (Dificid – Optimer), a new oral macrolide antibiotic, for treatment of Clostridium difficile-associated diarrhea in patients ≥18 years old. The incidence and severity of C. difficile infection (CDI) have increased in recent years with the emergence of an epidemic hypervirulent strain (NAP1/B1/027), possibly related to widespread use of fluoroquinolones.

The FDA has approved deferiprone (de fer’ i prone; Ferriprox – ApoPharma), an oral chelating agent available in Europe since 1999, for use as a second-line treatment of iron overload due to blood transfusions (transfusional hemosiderosis) in patients with thalassemia. Two other iron chelating agents, deferoxamine (Desferal, and others), which is usually administered subcutaneously, and oral deferasirox (Exjade), are available for use as first-line therapy in the US.

The FDA has approved a new formulation (Exparel – Pacira) of the local anesthetic bupivacaine (Marcaine, and others) for use in the management of postsurgical pain in adults.

The FDA has approved vismodegib (vis moe deg´ ib; Erivedge – Genentech), the first hedgehog (Hh) pathway inhibitor, for oral treatment of metastatic basal cell cancer, locally advanced basal cell carcinoma that has recurred after surgery, or locally advanced basal cell carcinoma in adults who are not candidates for surgery or radiation.

Icosapent ethyl (Vascepa [vas EE puh] – Amarin), the ethyl ester of eicosapentaenoic acid (EPA), has been approved by the FDA as an adjunct to diet for treatment of severe hypertriglyceridemia (≥500 mg/dL). Vascepa is the second omega-3 polyunsaturated fatty acid (PUFA) product to become available by prescription for this indication; Lovaza (formerly Omacor), which is a combination of the ethyl esters of EPA and docosahexaenoic acid (DHA), was the first. Many omega-3 PUFA-containing fish oil capsules are sold over the counter as dietary supplements.

The FDA has approved omacetaxine mepesuccinate (Synribo – Teva), a cephalotaxine known for many years as homoharringtonine, for treatment of adults with chronic or accelerated phase chronic myeloid leukemia (CML) who are no longer responding to, or who could not tolerate, two or more tyrosine kinase inhibitors.

An article published in the New York Times on May 1, 2015 listed the 10 drugs on which Medicare Part D spent the most in 2013. The most costly ($2.53 billion) was the proton pump inhibitor (PPI) Nexium (esomeprazole magnesium), which has recently become available generically.

Palbociclib (Ibrance – Pfizer), an oral cyclin-dependent kinase inhibitor, has been approved by the FDA for use in combination with the aromatase inhibitor letrozole (Femara, and generics) for first-line treatment of postmenopausal women with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer. It is the first cyclin-dependent kinase inhibitor to become available in the US.

Eteplirsen (Exondys 51 – Sarepta), an antisense oligonucleotide, has received accelerated approval from the FDA for treatment of Duchenne muscular dystrophy (DMD) in patients who have a mutation of the dystrophin gene that is amenable to exon 51 skipping. It is the first drug to be approved for treatment of DMD.
