When the first world congress in pharmacology was held in Stockholm in 1961
clinical pharmacology was barely visible in the scientific programme. The most
recent congresses in San Francisco (1972), Helsinki (1975) and Paris (1978) had
representative sessions in clinical pharmacology ofhigh scientific calibre. Due to the
medicine, paediatrics and psychiatry, a need developed to organize an international
meeting focussing entirely on clinical pharmacology matters . The original suggestion
by Professor Colin Dollery to organize such a meeting was therefore enthusiastically
received by our Section ofClinical Pharmacology and , even more important, by our
colleagues in basic pharmacology in IUPHAR.
The interdisc iplinary nature of clinical pharmacology is both a strength and an
inherent weakness. It is a strength in the sense that our research methodology often
penetrates into several branches ofmedicine. As an example - the controlled clinical
trial may be looked upon as one of the main advances of modern medicine and its
principles are today widely acknowledged in the scientific community. While the
cardiac catheter has remained an important identity tool for the cardiologists few
people today seem to recognize the link between controlled drug evaluation and
clinical pharmacology. Dr Franz Gross (1978) recently expressed this in a
commentary entitled 'The thorny path of clinical pharmacology' - 'despite the fact
that, in continuing education programmes therapeutic topics enjoy wide attention,
Let us carry out abrief retrospective critical analysis of the development (some
pessimists would say lack of development) of our discipline . This should not be
difficult since the past of clinical pharmacology is as short as 20 years, which is only
one half-life ofan average professional career in medicine!
'In the early and mid-sixties, a number ofwell-written articles appeared, mainly in
American and British medical journals that tried to foresee specific areas of research,
teaching and service in clinical pharmacology (Carr, 1963; Crout, 1965; Dollery,
1966; Lasagna, 1962, 1966; Wilson, 1963). It was pointed out that the preoccupation
with problems of diagnosis and pathogenesis had left the scientific study of drug
treatment relatively neglected (Dollery, 1966) and that therefore there was a great
need for drug oriented physicians in medicine. It was particularly underlined that
pharmacology units ought to develop and teach the methodology of controlled drug
evaluation in man in one or several areas (Lasagna, 1966). This point is equally
important today (Breckenridge, 1980).
InitiaIly too much time was spent on debating whether the skills of the clinical
pharmacologists ought to be those of the clinical investigator with a knowledge in
pharmacology or those of a pharmacologist with an interest in clinical medicine. At
the Anglo-Scandinavian symposium on 'Clinical pharmacology and patient care'
held in Newcastle in 1977, British and Scandinavian clinical pharmacologists
representing these two different schools with respect to basic training found that after
several years in the discipline they were doing very similar things and had similar
perspectives regarding the future directions.
'Clinical Pharmacology - Scope, organization, training', areport of a WHO study
group working in December 1969 under the chairmanship of Sir Derrick Dunlop,
might be the single most important publication on clinical pharmacology. Not only
does it contain a simple defmition ofclinical pharmacology as a field 'connected with
the scientific studies ofdrugs in man ' but also outlines the main functions ofa clinical
pharmacologist or rather a clinical pharmacology unit as:
I) to improve patient care by promoting the safer and more effective use of drugs
2) to increase knowledge through research
3) to pass on knowledge through teaching and
4) to provide services such as drug information, drug analysis, monitoring drug usage
and advice on experimental design.
Although clinical pharmacology operates in three distinct places: university
medical centres, the pharmaceutical industry and drug control, I shaIl limit most of
my comments to the problems and chaIlenges of clinical pharmacology as an
academic and health care discipline. WardeIl (1970) has reviewed, in agiobai
perspective, how the different functions listed by the WHO expert group are
implemented in the academic context. Not surprisingly he found that there are few
complete departments or divisions of clinical pharmacology having the broad
doctors to choose a field lacking a defmed career structure. One of the most
important reason s for the continuous growth of clinical pharmacology as an
integrated research , teach ing and health-care discipline in Great Britain and the
Nordic countries may very weIl be the creation of a subspeciality with a defmed
curriculum structure. EquaIly important is national, long-term planning regarding
the need and ava ilability of academic and other posit ions in clinical pharmacology.
The unsatisfactory recruitment to clinical pharmacology is of particular concern at a
time when clinical investigators are becoming an endangered species. Countries
paying attention to this problem have much to learn from the splendid achievements
ofclinical pharmacology in the UK .
While the controIled clinical trial and quantitative drug evaluation particularly in
hypertension were the main contributions of clinical pharmacology to medicine
during the early sixties, advances in human drug metabolism and pharmacokinetics
dominated the research contributions during the late sixties and early seventies.
Much credit for these developments should go to men like James Shannon and
Bernard B. Brodie at NIH who pioneered the development of drug analysis in body
fluids already while working at the Goldwater Hospital. Research on interindividual
Disease-mediated changes in kinetics and drug response were identified . Clinical
pharmacologists came to playa decisive role in research on drug interactions - and
they still do. The concept of individualization of drug therapy was born and as a
consequence rapid progress was seen in drug plasma level monitoring of a variety of
