Insulin detemir (Levemir - Novo Nordisk) is the second long-acting basal insulin analog to be marketed in the US for treatment of both type 1 and type 2 diabetes. Detemir differs from human insulin by the elimination of the amino acid threonine in position B30 and the addition of a 14-carbon fatty acid chain at position B29. Insulin glargine (Lantus), the first long-acting insulin analog, has been available since 2001 and is usually given once daily.1 NPH insulin is an intermediate-acting basal insulin given twice daily. Basal insulins are usually combined with prandial doses of a rapid-acting...

Golimumab (Simponi - Centocor), a fully humanized anti-tumor necrosis factor (TNF)-a antibody, has been approved by the FDA for the treatment of: (1) moderate to severe active rheumatoid arthritis (RA) in combination with methotrexate; (2) active psoriatic arthritis (PsA) alone or in combination with methotrexate; and (3) active ankylosing spondylitis (AS).

The FDA has approved ceftolozane/tazobactam (Zerbaxa – Cubist), a combination of a new cephalosporin antibiotic and a beta-lactamase inhibitor, for intravenous treatment of complicated urinary tract and intra-abdominal infections in adults.

The FDA has approved Toujeo (Sanofi), a more concentrated form of insulin glargine containing 300 IU/mL compared to the 100 IU/mL in Lantus (Sanofi). Lantus is nearing the end of its patent protection in the US, and biosimilars are expected to become available.

Epirubicin, an analog of doxorubicin that has been available in Europe and Canada for 15 years, has now been approved by the FDA for adjuvant use after resection of the primary tumor in breast cancer patients with axillary node involvement.

Argatroban, a small-molecule synthetic derivative of L-arginine, is a direct thrombin inhibitor approved by the FDA for use as an anticoagulant in patients with heparin-induced thrombocytopenia (HIT).

Methylphenidate is now available in a new extended-release formulation (Metadate CD - Celltech) for treatment of attention deficit/hyperactivity disorder (ADHD). The new product, which is a Schedule II controlled substance, is being advertised directly to consumers.

A once-weekly 35-mg oral formulation of the bisphosphonate risedronate (Actonel) has been approved by the FDA for prevention and treatment of postmenopausal osteoporosis. A once-weekly formulation of alendronate (Fosamax) was approved last year (Medical Letter 2001; 43:26). Bisphosphonates bind to the mineral surface of bone and decrease osteoclast activity, inhibiting the resorption phase of the bone turnover cycle. These drugs are not metabolized and remain bound to bone for several weeks.

When the use of aspirin for primary prevention of cardiovascular diseases was last reviewed in The Medical Letter, only one placebo-controlled prospective trial was available: the (male) Physicians' Health Study. Last year, a second large, randomized, placebo-controlled study was reported as part of the Women's Health Study. Recently a sex-specific meta-analysis of 6 trials, including these two, was published.
