Robert Smith: Pharmacologist Who Pioneered Personalized Medicine Dies at 92

The Lead

Robert Smith, a distinguished pharmacologist and professor at St Mary's medical school in London (now part of Imperial College), has died aged 92. His groundbreaking work on how genetic variations affect drug responses helped shape the field of personalized medicine.

The Discovery of Debrisoquine Polymorphism

Bob became well known for his role in the discovery of "debrisoquine polymorphism." In 1975, as one of five volunteer researchers who took debrisoquine, a blood pressure medication, he was the only one to suffer adverse effects (hypotension) and collapse. This led to the discovery of a genetic polymorphism where certain individuals cannot break down specific drugs efficiently. While Bob described this as an "accident waiting to happen," it positioned him at the forefront of pharmacogenetics.

Awards and Recognition

Smith's contributions to pharmacology were formally recognized when he became the first recipient of the Paton prize in 1998 for his work in understanding how genes affect drug response. His academic achievements included becoming professor of pharmacology in 1978 and serving as deputy dean of the medical school from 1980-88.

Impact on Medicine and Sports

Smith's research fundamentally changed how medical professionals understand drug responses, paving the way for personalized medicine approaches. Beyond human medicine, he applied these principles to horse racing, chairing the UK Horserace Scientific Advisory Committee (1979-99) and its pan-European equivalent (1992-2005). He also served as a director of the Horseracing Forensic Laboratory in Newmarket during the 1990s, helping shape anti-doping protocols.

Enduring Legacy

Smith never fully retired, continuing his research as emeritus professor until publishing his last paper in 2020. His legacy extends beyond scientific contributions to include the principles, warmth, kindness and generosity he embodied throughout his career. His work continues to influence pharmacology and personalized medicine, ensuring his impact will be felt for generations to come.
