Instructions for Authors

The Japanese Journal of Clinical Pharmacology and Therapeutics(the Journal)is a journal published by the Japanese Society of Clinical Pharmacology and Therapeutics(the Society). The Journal publishes papers on all aspects of interdisciplinary research concerning human pharmacological treatment, with the goal of contributing to the advancement of the fields of clinical pharmacology and therapeutics not only within Japan but globally. The areas of study from which the Journal awaits submission of original papers are as follows:clinical studies concerning the development of new medicines or treatments intended for human use and the ethics thereof;translational research;research on individualized pharmacological treatment including pharmacogenomics;research on interactions with medicine, environmental factors, and nutrition relating to variability in drug responses;pharmacokinetics and pharmacodynamics research;pharmacometrics research;pharmacoepidemiology research;research on medical economics relating to pharmacological treatment;regulatory science research;topics of the education of clinical pharmacology and therapeutics;and any other related topic that authors consider to be within the purpose and goal of the Journal. The target audience for the Journal comprises medical doctors, pharmacists, nurses, clinical research coordinators(CRCs), and others involved in pharmacological therapy, who are members of the Society. Moreover, the Journal offers a platform for vigorous discussion of political issues of medicines and review articles related to the above fields.

1.Types of Articles Eligible for Submission
The Journal accepts Original Articles, Short Communications, Case Reports, Review Articles, Forums, Letter to the Editor, and Reports. Submitted articles must be previously unpublished in other journals nor currently under review by other journals.
Original Article:
Japanese Journal of Clinical Pharmacology and Therapeutics(JJCPT)will accept submissions of articles which aim to answer previously unknown or unsolved issues in the discipline of clinical pharmacology and therapeutics. They may be experimental, observational, and randomized clinical trials with intervention in design. Submissions of pharmacoepidemiologic studies including meta-analyses of randomized trials, cost-effectiveness analyses on health care databases, and analyses of adverse drug reaction databases are also welcome.
Short Communication:
An interim report that justifies urgent publication, and one that would ultimately be published in final form as part of an Original Article.
Case Report:
A clinical case report that raises important aspects to be discussed in the light of pharmacological therapy, such as adverse reactions or interactions, using information from a single patient or a few patients.
Review Article:
An article that expresses the author’s views on the results of a highly relevant Original Article within the Journal’s fields.
Accounts, recommendations, or proposals to research ethics, regulations of academic or clinical experiments, and other areas of clinical pharmacology and therapeutics which may not be considered for publication in original articles may be accepted in this category.
Letter to the Editor:
Expresses a reader’s inquiries or opinions about a paper or article published in the Journal.
An article about the activities of the Society designed to communicate relevant information via the Journal(for example, reports by the awardees of the Foreign Clinical Pharmacology Training Program after the completion of the program).
2.Submission Requirements
Members and nonmembers of the Society may submit articles. However, if the first author is not a member of the Society, a submission fee must be paid(see 12.1).
3.Author Requirements
To be published as an author, the following three requirements must be satisfied:He/she 1)has made a suitable contribution to the paper’s conception and design, acquisition of data, analysis, and discussion, 2)participated in drafting the paper or in critical proofreading concerning its essential intellectual content, and 3)was responsible for final confirmation of the submitted manuscript.
4.Editorial Review
A manuscript will be accepted or rejected for publication upon review by a number of specialists. If it is accepted, revisions to the manuscript may be requested. Articles are generally published in order of submission, but due to circumstances of judging or editing, the order may be changed. Furthermore, for clinical studies with human subjects, statements of compliance with the Declaration of Helsinki, documentations of the approval by the ethics committees of relevant medical institutions, and documentations of the acquisition of written informed consent from participants of the study must be clearly written in the manuscript. Furthermore, if a clinical study submitted to the Journal is prospective and confirmatory in design, authors are required to register the study with a registry that meets the standards of the International Committee of Medical Journal Editors(ICMJE), such as the jRCT, UMIN Clinical Trials Registry.
5.Submitting a Manuscript
  • 5.1 Submit the manuscript at the designated URL(http :// This URL is available on the Society’s website(the Journal page), and an online submission manual(in Japanese)is also available there. Please follow all the instructions within the submission system regarding file formats.
