The use of drugs as remedies for various types of diseases has a long tradition. However, it has only been recently recognized that the value of any given compound must be evaluated in light of its benefit to risk ratio. When prescribing drugs, physicians must look at the big picture of the drug's benefits in relation to its side effects and possible toxicity. The aim of this handbook is to compile data from various authors, providing clinicians with data that will optimize their decision making in selecting effective, low-risk drug treatments.
