Why do we need Clinical

Pharmacologists?To solve this problem

What is the problem in a bigger context?

For most of the DAILY drugs that people take, we do not know whether the

benefits outweigh the harms.

Page 23: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

How I became a Clinical Pharmacologist

2 years undergrad in Science (Experimental Psychology)

4 years medical school (University of Alberta) including summer research in Pharmacology lab.

1 year rotating internship Montreal General Hospital (MGH).

1 year Internal Medicine resident at MGH

1 year Teaching Fellow in Nairobi, Kenya.

Page 24: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

My training (cont)4 years combined Doctoral research and Internal

medicine residency training (Dept of Pharmacology and MGH, McGill University).

1975-76, one year Post doctoral training in Clinical Pharmacology at Hammersmith Hospital, London, UK

Page 25: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

My degrees MD, University of Alberta 1968

PhD, McGill University, 1976

FRCP(C), Internal Medicine, 1975

Page 26: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

My journey at UBCFirst Phase

1977 Assistant professor in Pharmacology & Therapeutics and Medicine.

Clinical Pharmacologist – Clinical practice, (in hospital consultations and outpatient clinic).

1977-1983, MRC funded basic research into mechanisms of adverse drug effects and drug interactions.

Teaching – Pharmacology to Medical students, Graduate students.

Page 27: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

My journey at UBC Second Phase

In 1983 I began doing clinical trials (mostly drug industry funded on new antihypertensive drugs).

Between 1983 and 1994, I was principal investigator for 15 trials with >10 different drug companies.

Examples of drugs studied: fosinopril, irbesartan, terazosin, lemakalim, etc.

Page 28: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

My journey at UBCThird Phase

In 1994 the Therapeutics Initiative was formed and I was appointed the Clinical Managing Director.

I stopped all drug industry funded research.

1994 to present -- main activity, Managing Director of TI and Editor-in-Chief of Therapeutics Letter.

2001, I was appointed Coordinating Editor of the Cochrane Hypertension Review Group.

Page 29: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

My journey (cont)3 sabbaticals, Stockholm, Sweden (85-86);

Wellington, New Zealand (96-97); Lyon, France (2005-6).

Many changes and variety of work during my career.

Understanding drug effects is extremely complex, interesting and challenging.

I enjoy the fact that I do different things almost every day.

ConclusionsYou already have a good background training in

Pharmacology.

Clinical Pharmacology is interesting, highly challenging and greatly needed.

Prescription drugs are not used optimally and are a major cause of unnecessary death.

Page 38: Clinical Pharmacology 400 2014 Jim Wright Clinical Pharmacologist 7 lectures

Conclusions (cont)Physicians both family practitioners and

specialists are not adequately trained in Clinical Pharmacology.

Physicians are highly vulnerable and unknowingly influenced by Big Pharma.

Because number and complexity of drugs is expanding Clinical Pharmacologists are badly needed.
