The At a Glance series sets out to summarize the essential information about a particular subject for the student requiring a quick introduction or a guide to revision. This is done by taking each aspect of the subject in turn and condensing it into a two-page spread with a schematic diagram on the left and a concise explanation on the right. Retaining the very visual presentation of the first edition, this book has been revised fully, ensuring that developments in the field of medical pharmacology have been taken into account. New chapters cover antifungal and antiviral drugs, antiprotozoal drugs, and drug misuse and dependence.
