Ibuprofen's Origin Story is Weird

Ibuprofen is one of the most consumed drugs on earth — taken billions of times a year for headaches, fevers, muscle pain, inflammation, and a dozen other complaints so routine that most people reach for it without a second thought, the way they'd reach for a glass of water. Almost nobody knows where it came from. The origin story of ibuprofen is stranger, more personal, and more driven by individual obsession than almost any other drug in the modern pharmacopeia — beginning with a British chemist named Stewart Adams who spent over a decade pursuing a molecule that his own company wasn't sure was worth developing, tested the first human dose on himself the morning of a diplomatic speech because he had a hangover and wanted to see if it worked, and ultimately helped bring to market a drug that would go on to be used by more people than almost any other pharmaceutical compound in history. This explainer traces the full story: the post-war pharmaceutical landscape that made finding a safer alternative to aspirin one of the most commercially important problems in medicine, the years of dead ends and abandoned compounds that preceded the ibuprofen breakthrough, Adams and his colleague John Nicholson's synthesis of the molecule that finally worked, the decade-long battle to get it approved and then released over the counter, and the self-experiment that remains one of the most casually audacious moments in the history of drug development. It's the origin story of the pill in your medicine cabinet — and it turns out to be far weirder and more human than the clinical packaging suggests.
