Benefit-Risk Appraisal of Medicines [PDF ebook] 
A Systematic Approach to Decision-making

Benefit-risk assessment is at the centre of the approval process
for every new medicine. The ability to assess the risks of a new
medicine accurately and to balance these against the benefits the
medicine could bring is critical for every regulatory authority and
pharmaceutical company. Despite this there are very few tried and
tested evaluative models currently available.

The authors of this book have developed a new, pioneering tool
for the assessment of benefits and risks for new medicines in
development. This model utilises a multi-criteria decision analysis
which involves selecting, scoring and weighting key benefit and
risk attributes and leads to an overall appraisal of benefits and
risks of medicines.

Benefit-Risk Appraisal of Medicines establishes the
background and criteria required to assess benefit and risk in
general and reviews the current practices by regulatory authorities
and the pharmaceutical industry, including those models currently
available. It outlines the development and evaluation of the
authors’ new model and analyses the implications of its
implementation.

* Describes an innovative, systematic model which leads to
transparent and responsible benefit-risk decision making

* Contributes important ideas to the debate on benefit-risk
appraisal

* Provides a future framework for benefit-risk appraisal of
medicines

Benefit-Risk Appraisal of Medicines covers the entire
process from the discovery of new medicines to their marketing and
is ideal for all those who work in the pharmaceutical industry and
regulatory authorities, , as well as post-graduate students of
pharmaceutical medicine and clinical pharmacology.
