| Abstract
|
:
|
This handbook charts the processes involved in the discovery, development and final clinical utilization of a new drug for fungal diseases. Its purpose is to help the specialist involved at just one stage appreciate the need for and contributions by the many others involved in the complex process of drug discovery and development. Five groups of readers will benefit from this volume. The experimentalist will find stimulation and provocation concerning approaches to drug discovery and screening. The expert responsible for the evaluation of the safety of drugs will find background information to help deliniate the biochemical, pharmacokinetic and toxicological properties of candidate compounds. The clinician will find an appreciation of the effort necessary to develop new agents. The academic will find an overview of the non-academic aspects; and the manager will see the urgent needs and opportunities which the field of antifungal chemotherapy presents to the pharmaceutical industry.
