Product Description: This data collection compiles over 150,000 synonyms and molecular structures of more than 16,000 synthetic drugs used for their identification, e.g. names adopted by certain institutions, common names, names adopted by manufacturers, experimental names, abbreviations, and the non-proprietary names proposed by the World Health Organisation (WHO). The indices makes drug search even easier and more efficient. The 8th edition has been enlarged by almost one third taking into account the rapidly increasing number of the newly developed drugs.
