Barring a few exceptions (such as rauwolfia), most of the psychiatric medications have been developed in the West, especially the USA, the UK and Europe. Their safety trials have been conducted in the populations living in these parts of the world. Although these drugs are used all over the world there is a limited research to determine accurate pharmacodynamic and pharmacokinetic profiles across different ethnic groups. Hence, clinicians usually adopt a ‘universalist style’ (seeing every condition and treatment as similar) of managing psychiatric illnesses, but this appears to neglect the information from the emerging literature which advocates a relativist approach to pharmacotherapy (see Lin et al 1995 for review). Anthropologists have encountered ‘phenomenological absolutism’ in a general tendency of people from one culture to perceive and value other cultures in terms unconsciously based upon their own, but phenomenologically experienced as absolute and universally applicable (also known as ethnocentrism). In addition to ethno-biological determinants of drug response, there are significant cultural factors: the concurrent use of pluralistic health systems, alternative therapies and folk remedies which might support, hinder or complicate pharmacotherapy and treatment adherence. In this paper we highlight some key factors of which clinicians need to be aware. These include pharmacodynamic and pharmacokinetic principles, and application of these principles in pharmacological management of psychiatric conditions. Ethnic differences in pharmacodynamics are most clearly demonstrated in the greater sensitivity to a variety of drugs in Caucasians than in Asians or in African–Caribbeans.
