What did the Kefauver-Harris Amendment address in terms of drug marketing?

The Kefauver-Harris Amendment, enacted in 1962, primarily focused on ensuring that drugs not only be safe for consumption but also effective for their intended uses before they could be marketed. This amendment required that manufacturers provide proof of the effectiveness of their drugs, in addition to their safety, significantly changing the regulatory landscape of pharmaceuticals. Prior to this amendment, the process did not mandate such proof, which often led to the circulation of ineffective medications. The amendment was a response to growing concerns over the efficacy of drugs that were available, spurred by public health crises, most notably the thalidomide tragedy.

The requirement for drug effectiveness proved to be a crucial safeguard, helping to ensure that patients receive medications that deliver real therapeutic benefits. This change contributed to the establishment of more rigorous standards for drug approval, which continue to affect pharmaceutical marketing practices today.

In contrast, while safety of ingredients, advertising regulations, and prescription labeling are important aspects of pharmaceutical law and regulation, the Kefauver-Harris Amendment specifically targeted the need for proof of effectiveness as a central requirement for drug marketing.
