The prescription of psychotropic Inhibitors,research,lifescience,medical medicines across all age groups is rising worldwide [Wong et al. 2004; Exeter et al. 2009; Deambrosis et al. 2010; Verdoux et al. 2010; Ilyas and Moncrieff, 2012], comprising a US$330 billion market [Murashev, 2012], more than Inhibitors,research,lifescience,medical a third of global pharmaceutical sales. In the US antidepressants comprise the largest category of prescribed
drug ranked by expenditure, and their use continues to increase by around 20% each year. The prescription of antipsychotic medicines, 13th by expenditure, is increasing even more rapidly [Zuvekas, 2005]. In England, the estimated health, social and informal care cost for mental illness was £22.5 billion per annum in 2007 [McCrone, 2008]. Within this, psychotropic medication is a significant area of growth, as antidepressant prescriptions have increased by 10% and antipsychotics by 5% year on year [Ilyas and Moncrieff, 2012].

In the UK a drug’s marketing authorization specifies its licensed dose range, form and target disorders, a role performed by the Medicines and Healthcare products Regulatory Agency (MHRA) and the Food and Drug Administration (FDA) in the many US. These agencies are primarily concerned with defining the market entry requirements of medicines rather than policing future prescribing practices. In the UK the MHRA process for licensing medicines before they come to market is governed by UK and European Union law. The MHRA assess the quality, safety and efficacy data submitted to it from human clinical trials determined, designed and conducted by the pharmaceutical companies.
