The future of medicine means revisiting older, cheaper drugs armed with new genetic knowledge, according to professor of Clinical Pharmacology and Therapeutics at Warwick Medical School, Professor Donald Singer.

In an article prepared for Reuters News Agency, Professor Singer said recent studies had revealed clues as to why medicines work better in some patients than others. He suggested combining new tests with old drugs would be more cost-effective.

He said: "In the last year or so people have been beginning to find gene markers in much more common areas. We are really on the cusp at the moment in terms of the cost effectiveness."
