This book provides reliable, unbiased and evaluated information on drugs and medicines used throughout the world. Each new drug licensed for use has its own potential benefits and adverse effects, and its own profile for dosage, administration and indications. Furthermore, manufacturers make regular changes to existing drug names and formulations, which can affect their interactions and safe usage. Health professionals require the correct answers and need to have confidence in the drugs information they use - but with medicines evolving at this rate, how can they be sure their knowledge is up to date? "Martindale" contains up to date information about more than 5,800 substances. Each and every entry is reviewed by our pharmaceutical editors to ensure health professionals have the most current data. Formulations change. Definitions change. Names change. But you can always trust "Martindale".
