Has America become a nation of psychotics? You would certainly think so, based on the explosion in the use of antipsychotic medications. In 2008, with over $14 billion in sales, antipsychotics became the single top-selling therapeutic class of prescription drugs in the United States, surpassing drugs used to treat high cholesterol and acid reflux.

Once upon a time, antipsychotics were reserved for a relatively small number of patients with hard-core psychiatric diagnoses – primarily schizophrenia and bipolar disorder – to treat such symptoms as delusions, hallucinations, or formal thought disorder. Today, it seems, everyone is taking antipsychotics. Parents are told that their unruly kids are in fact bipolar, and in need of anti-psychotics, while old people with dementia are dosed, in large numbers, with drugs once reserved largely for schizophrenics. Americans with symptoms ranging from chronic depression to anxiety to insomnia are now being prescribed anti-psychotics at rates that seem to indicate a national mass psychosis.

It is anything but a coincidence that the explosion in antipsychotic use coincides with the pharmaceutical industry’s development of a new class of medications known as “atypical antipsychotics.” Beginning with Zyprexa, Risperdal, and Seroquel in the 1990s, followed by Abilify in the early 2000s, these drugs were touted as being more effective than older antipsychotics like Haldol and Thorazine. More importantly, they lacked the most noxious side effects of the older drugs – in particular, the tremors and other motor control problems.

The atypical anti-psychotics were the bright new stars in the pharmaceutical industry’s roster of psychotropic drugs – costly, patented medications that made people feel and behave better without any shaking or drooling. Sales grew steadily, until by 2009 Seroquel and Abilify numbered fifth and sixth in annual drug sales, and prescriptions written for the top three atypical antipsychotics totaled more than 20 million. Suddenly, antipsychotics weren’t just for psychotics any more.
