[BDSP. Notice produite par INIST-CNRS 1sc2R0x0. Diffusion soumise à autorisation]. A revised version of the Declaration of Helsinki, Issued in October, 2000, remains a vital expression of medical ethics, and deserves unanimous support. A strict Interpretation of the declaration seems to rule out clinical trials that use a placebo control group whenever licensed therapeutic methods already exist, preferring active controls. Although the efficacy of some new medicines can be satisfactorily established without the use of a placebo, for others the Judicious use of placebo remains essential to establish their effectiveness.
