Preface
This volume of the Handbook of Experimental Pharmacology
(Concepts in Biochemical Pharmacology) will show that pharma
cology has finally arrived as a true discipline in its own right, and
is no longer the handmaiden of organic chemistry and physiology.
Instead it is an amalgam of all the biological sciences including
biochemistry, biophysical chemistry, physiology, pathology and
clinical medicine. In the volumes that make up Concepts in Bioche
mical Pharmacology we hope to convince Medical Schools what
should now be obvious, that pharmacology is no longer that dull
topic bridging the basic sciences with medicine, but is probably
the most important subject in the medical curriculum.
We are grateful for the advice of Dr. BYRON CLARKE, Director
of the Pharmacology-Toxicology Program at the National Insti
tutes of Health, whose support made possible much of the work
described in this volume.
