Management controls on prescribing have greater impact on a GP's freedom of choice than on any other matter requiring clinical judgement. However, in order to deliver the most effective patient care, the GP needs a much broader base of knowledge including, for example, an understanding of basic pharmacological principles and the process of conducting clinical trials. This book deals systematically with the practical aspects of prescribing throughout primary care. It provides the busy GP with readily-accessible information so that the benefit to patients and the pratice can be maximized.
