Medicinal Research Reviews publishes timely, critical reviews and opinion-based articles on topics related to medicinal research, broadly defined, to which the authors have made significant contributions. Appropriate topics include, but are not limited to, the underlying pathophysiology of important diseases and disease vectors; therapeutic approaches to the treatment of various diseases; the properties of molecular targets for therapeutic agents; important new methodologies facilitating the search for therapies; genomics and proteomics; structure-activity correlations of drug series; the development of new imaging and diagnostic tools; drug metabolism; drug delivery; and chemical, pharmacological, pharmacokinetic, pharmacodynamic, and clinical characteristics of important drugs. Articles are mainly solicited by the Editors; however, voluntary contributions are also encouraged. In the latter case, authors are asked to include a "Review Summary Sheet" with their submission. This Sheet is available for download here: MRR Review Summary Sheet template and more details can be found in the Author Guidelines.
