Franz Gross died suddenly during preparations for the meeting. He would have taken great pleasure in summarizing in this preface the aims and results of a gathering which so clearly bore his imprint as Chairman of the Scientific Program Committee. His sudden passing away is deeply regretted by all of us: organizers, speakers and participants. We greatly respect him for his exceptional abilities, his impact on science and his qualities as a human being. He provided the impulse for a well balanced and topical scientific program. We therefore dedicate the proceedings of this symposium to his memory. Munich was the fifth in a traditional line of international meetings of pharmaceutical physicians held at three-year intervals, starting in London in 1972 ('International Aspects of Drug Evaluation and Usage'), and followed by Florence in 1975 (, Rationality of Drug Development'), Brussels in 1978 (, Pharmaceutical Medicine - the Future') and Paris in 1981 ('Drug Safety -;- Progress and Controversies'). This 5th meeting discussed improvements in drug development and application and examined the impact of regulatory activities.

When I was asked some years ago by the editors of the Handbook of Experimental Pharmacology to edit a new volume on Antianginal Drugs, I agreed on the condition that, in accordance with my scientific background, primary emphasis be given to clinical pharmacology and therapeutics. It soon turned out that, due to rapid developments in this field, nothing of the previous volume on Antianginal Drugs by Charlier (Vol. 31, 1971) could be retained apart from its basic idea of devoting considerable space to methodology. Since editors must operate within certain limits, I had to abstain from dealing with acute myocardial infarction in detail despite the well-known overlap between unstable angina, the preinfarction syndrome, and acute myocardial infarction. It was only possible for acute myocardial infarction and the concept of reduction of infarct size to be briefly discussed within the chapter on pathophysiology of acute coronary insufficiency. The chapter on invasive methods provided an opportunity to touch on new approaches to early intervention in acute myocardial infarction. Here, intracoronary streptokinase therapy and PTCA are considered, again with attention to the overlap between mechanical and pharmacological interventions.
