Modern clinical psychopharmacology can be dated from the introduction of lithium carbonate to treat mania by John Cade in Australia in 1949 or from the introduction of chlorpromazine as the first synthetic drug found to be effective in both mania and psychotic disorders in Paris in the early 1950s. Soon thereafter, the mood-elevating effects of the monoamine oxidase inhibitor, iproniazid, and the antidepressant effects of imipramine were reported. By 1960, haloperidol, the first butyrophenone antipsychotic, the first so-called atypical antipsychotic, clozapine, and benzodiazepines also were introduced. That is, at least one agent from each major class of currently employed psychotropic drugs was known by the end of the 1950s. These new treatments brought about fundamental changes in the treatment of many major psychiatric disorders of unknown cause—notably, mania, depression, acute and chronic psychotic disorders, including schizophrenia, as well as severe anxiety disorders. These changes can fairly be considered revolutionary. Moreover, their impact extended far beyond improvements in treatment, and included fundamental changes in the conceptualization of most psychiatric disorders, in their diagnosis and categorization, on models for research into the nature of psychiatric illnesses, on psychiatric education, on methods and standards for experimental therapeutics, and on the organization of modern psychiatry as a clinical and academic medical specialty. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
