The US Food and Drug Administration recently approved the marketing of ioversol (Optiray - Mallinckrodt), a new iodinated, low-osmolality, non-ionic X-ray contrast agent. Low-osmolality contrast agents are much more expensive, but they provide as good diagnostic quality as older, high-osmolality contrast media and are claimed to be both better tolerated and safer (Medical Letter, 29:43, 1987).

Naltrexone (ReVia -DuPont Pharma), a long-acting oral opioid antagonist previously marketed for treatment of opioid dependence under the trade name Trexan, was recently approved by the US Food and Drug Administration (FDA) for treatment of alcohol dependence. The new trade name will now also be used for the old indication.

Agalsidase beta (Fabrazyme Genzyme) has received accelerated approval from the FDA for treatment of patients with Fabry disease, an inherited lysosomal storage disease caused by deficiency of α-galactosidase A. Agalsidase beta is a recombinant form of human α-galactosidase A. This review provides an overview of this rare disease, including its clinical manifestations. The clinical trials conducted with the new drug are also described, as well as its adverse effects, dosage, and cost. Appropriate indications for use of Fabrazyme are summarized.
