Psychopharmacology

The goal of this clinical and pharmacy practice-based research program is to optimize the use of psychopharmacological agents in clinical practice. These investigations relate to both enhancing therapeutic efficacy while minimizing harms related to psychotropic medication use. A major focus of this research program is the problem of prescription drug abuse (e.g., abuse and addiction to prescription opioids or benzodiazepines). The problem of prescription drug abuse is unique in the field of substance abuse for primarily two reasons: any strategy to prevent or reduce abuse, must be balanced with the need to make these pharmaceutical products readily available for therapeutic use; and a subset of individuals abusing pharmaceutical products may also have a therapeutic need for the drug, adding complexity to assessment, prevention and treatment approaches. In this research program different aspects of the problem are explored including characterizing the problem, understanding the influence of comorbidities (e.g., mental health disorders, other substance use disorders), understanding the role of health care providers and the health care system in this problem, and evaluating monitoring, prevention, harm reduction and treatment strategies. Several research methodologies are used to address the issues including conducting surveys and interviews, performing experimental pharmacokinetic/pharmacodynamic investigations and using pharmacy practice-based approaches and interventions.

The research is based at the Centre for Addiction and Mental Health (CAMH). CAMH is Canada’s largest mental health and addiction teaching hospital. CAMH combines clinical care, research, education, policy development and health promotion to help transform the lives of people affected by mental health and addiction issues. (www.camh.net).
