[Thalidomide once more in the spotlight].

Thalidomide was withdrawn from the market in the early sixties because of major teratogenic effects such as reduction defects of the limbs. Since, however, it has been found to be an effective drug in erythema nodosum leprosum. In the United States it was decided in September 1997 to admit thalidomide to the market for this indication, and in South America it has been available for this indication all the time. Thalidomide is also efficacious in other major disorders (e.g. aphtae and ulcers in aids) or its efficacy is being investigated in clinical trials (e.g. autoimmune diseases, other complications in aids). The American Food and Drug Administration has imposed conditions for the use of thalidomide. Users have to sign an informed consent and to take adequate contraceptive measures. Physicians should inform the patients and monitor side effects. Pharmacists should record and control the use.
