Because of concerns about the possibility of bioterrorism involving smallpox, the US government is reinstituting smallpox vaccination (https://www.cdc.gov/smallpox/; www.idsociety.org/bt/toc.htm). Vaccination is currently expected to proceed in three phases: the military and hospital smallpox response teams first, other health care workers, police and firefighters second, and the general public in the third phase. Except for the military, vaccination will be...

A 10-year study of daily oral alendronate (Fosamax) and a 7-year study of daily oral risedronate (Actonel) indicate that both drugs maintained increases in bone mineral density (BMD) and decreases in markers of bone remodeling throughout the study period. Both drugs are now more commonly taken once weekly. Available data are insufficient to compare fracture rates with alendronate and risedronate, and fracture rates are considered the most important endpoint in osteoporosis studies. Recent reports of severe pain and jaw osteonecrosis with these drugs are disturbing.

Dasatinib (Sprycel - Bristol-Myers Squibb), an inhibitor of multiple tyrosine kinases, has been approved by the FDA for second-line treatment of chronic myelogenous leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) in adults.

Eculizumab (Soliris - Alexion) has been approved by the FDA for reduction of hemolysis in patients with paroxysmal nocturnal hemoglobinuria (PNH), a rare form of hemolytic anemia. A recombinant humanized monoclonal antibody, eculizumab is the first drug to be marketed for this indication.

Tetrabenazine (Xenazine - Ovation Pharmaceuticals), an old drug first synthesized 50 years ago for treatment of schizophrenia, was recently approved by the FDA for the treatment of chorea associated with Huntington's disease. It has been available in other countries for decades.

In our October 26, 2015 article on drugs for hypothyroidism (Med Lett Drugs Ther 2015; 57:147), we said that levothyroxine should be taken on an empty stomach with a full glass of water 30-60 minutes (60 is preferable) before breakfast. We should have added that taking the drug consistently at bedtime, at least 3 hours after the last meal, is an alternative that some patients may find more convenient.

Production of erythropoietin, a glycoprotein hormone secreted mainly by the kidney, is often low in patients with chronic renal failure (JW Eschbach, Kidney Int, 35:134, 1989). The US Food and Drug Administration recently approved marketing of epoetin alfa (Epogen - Amgen), a recombinant human erythropoietin, for treatment of anemia in such patients. Epoetin is commercially available in Europe as Eprex (Ortho), and Eprex is available from Ortho in the USA on an investigational basis for treatment of anemia related to AIDS. Epogen and Eprex are chemically...

Lamotrigine (la mo tri jeen; Lamictal - Burroughs Wellcome), a phenyltriazine derivative, has been approved by the US Food and Drug Administration for use in addition to other antiepileptic drugs in adults with partial seizures. Since this diagnostic category includes the largest number of patients with intractable epilepsy, new drugs with antiepileptic activity are usually tried first for this indication. Lamotrigine was first marketed abroad in 1990 and is now available in more than 50 other countries.

Nefazodone (Serzone - Bristol-Myers Squibb) was recently approved by the US Food and Drug Administration for treatment of depression. A phenylpiperazine, nefazodone is chemically related to trazodone (Desyrel, and others).

Zafirlukast (za fir loo kast; Accolate - Zeneca), the first leukotriene receptor anta-gonist approved by the US Food and Drug Administration, is now being heavily promoted for oral maintenance treatment of chronic asthma in patients more than 12 years old. It is not recommended for treatment of acute asthma.
