The treatment of choice to prevent emesis due to highand moderate-risk emetogenic drugs used in cancer chemotherapy is aprepitant plus a serotonin receptor antagonist plus dexamethasone. Four serotonin receptor antagonists are available in the US in intravenous (IV) formulations for prevention of nausea and vomiting due to cancer chemotherapy, and 3 of these are also available for oral use. Now the FDA has approved one of these, granisetron, in a transdermal formulation (Sancuso - ProStrakan).

An extended-release injectable formulation of the second-generation antipsychotic aripiprazole (Abilify) has been approved by the FDA (Abilify Maintena – Otsuka/Lundbeck) for once-monthly treatment of schizophrenia. It is the fourth second-generation antipsychotic to become available in a long-acting parenteral formulation. Long-acting parenteral antipsychotics, given at intervals of 2-4 weeks, are generally used for patients with a history of relapse due to poor adherence to oral maintenance therapy.

Rosacea is a common, chronic inflammatory facial eruption of unknown cause. It is more prevalent in women than in men, and disease onset typically occurs after age 30. Rosacea is characterized by erythema, telangiectasia, and flushing, and sometimes by recurrent, progressive crops of acneiform papules and pustules, usually on the central part of the face. Some patients develop granulomas and tissue hypertrophy, which may lead to rhinophyma (a bulbous nose), particularly in men. Blepharitis and conjunctivitis are common. Keratitis and corneal scarring occur rarely.

Unlike new drugs, new techniques for surgery do not need the approval of any government agency. Laparoscopic cholecystectomy, made possible by the development of miniaturized television cameras, is one such technique that has recently attracted widespread interest (LW Way, N Engl J Med, 323:1273, Nov 1, 1990; R Winslow, Wall St J, 216:1, Dec 10, 1990).

Succimer (meso 2,3-dimercaptosuccinic acid; DMSA; CHEMET - McNeil), a heavy metal chelator, was recently marketed in the USA for oral treatment of lead poisoning in children.

Results of a recent study suggested that zinc gluconate may be effective in treating the common cold (SB Mossad et al, Ann Intern Med, 125:81, July 15, 1996). Zinc gluconate lozenges, sometimes combined with vitamin C or other ingredients, are available in pharmacies and health food stores throughout the USA.

The average daily intake of sodium in the US is about 3400 mg. Dietary guidelines recommend reducing it to <2300 mg/day in general, and to 1500 mg for African Americans, persons with hypertension, diabetes or chronic renal disease, and for all those >50 years old. Salt reduction lowers blood pressure, and lowering blood pressure reduces the risk of myocardial infarction, stroke and death.

The FDA has approved the antiprogestin mifepristone (Korlym – Corcept Therapeutics) for control of hyperglycemia secondary to hypercortisolism in adults with endogenous Cushing’s syndrome who have type 2 diabetes/ glucose intolerance and have not responded to, or are not candidates for, surgery. Formerly known as RU 486, mifepristone is also available in a lower strength as Mifeprex for use in terminating an early intrauterine pregnancy.

A recent article in JAMA and an interview of its senior author on 60 Minutes have heightened interest in off-label use of the oral selective serotonin reuptake inhibitor (SSRI) fluvoxamine (Luvox, and generics) to treat COVID-19.

The FDA has approved omidubicel-onlv (Omisirge – Gamida Cell), a nicotinamide-modified, allogeneic hematopoietic progenitor cell therapy derived from cord blood, to reduce the time to neutrophil recovery and the risk of infection in patients ≥12 years old with hematologic malignancies who will undergo umbilical cord blood transplantation following myeloablative conditioning therapy. Hematopoietic progenitor cell (HPC) umbilical cord products (e.g., Allocord, Clevecord, Ducord) have been available in the US for years for the same indication. Cord blood banks also supply cord...
