About Janusmed Sex and Gender

Introduction

Janusmed Sex and Gender is a knowledge database providing structured evidence-based information on sex and gender aspects of drug treatment. The purpose is to provide support for improved drug therapy by facilitating the right choice of drug and the right dosage, related to the patient’s sex. The text documents are based on substance names (generic names).

The knowledge database is primarily intended to be used by physicians and healthcare professionals. Please note that the information in the knowledge database is general and does not replace medical, clinical, or pharmaceutical assessment. The information should not be considered as treatment guidelines. The individual patient’s physician is responsible for the patient’s drug treatment. Therefore, patients who have questions are referred to their responsible physician.

About the content

Optimization of drug prescription and drug treatment in men and women is dependent on analyses of diseases and health with a sex and gender perspective. More evidence of great importance on differences between men and women in drug treatment, both from a biological and a sociological perspective, is continuously found.

In this context, the term ‘sex differences’ refers to biological differences, and the term ‘gender differences’ refers to differences related to attitudes in society as well as economic, ethnic, and socio-psychological differences.

The text documents in Janusmed Sex and Gender primarily contain information on biological sex aspects regarding pharmacokinetics, effects, and adverse effects. In addition, to some extent information on gender aspects e.g., disease prevalence, drug use, and adverse event reporting. The sex and gender differences in the text documents are statistically significant unless otherwise stated.

Please note that Janusmed Sex and Gender does not include information on possible drug effects on the fetus or if drug treatment is compatible with breastfeeding. For related information, please consult the knowledge databases Janusmed Drugs and Birth Defects (in Swedish, Janusmed fosterpåverkan) and Janusmed Breastfeeding (in Swedish, Janusmed amning).

The information in the knowledge database is based on systematic searches in scientific literature, other databases, and handbooks. The literature search follows a template (SOP) and a checklist to ensure that the authors follow the same systematic process and have enough information to write about substances that not yet have been included in the knowledge database, and to update existing text documents. The text documents are written by pharmacists or physicians. Before publication, all texts are reviewed by specialists in clinical pharmacology and approved by a senior professor. Updates of the content are done continuously. If necessary, the medical content is reviewed by clinical experts from Region Stockholm’s Drug and Therapeutic Committee’s expert groups within relevant therapy area. In addition, the Swedish Medical Products Agency or its American counterpart, the Food and Drug Administration, are consulted if necessary.

Most drugs in the database are also recommended in The Wise List of Region Stockholm. In addition, also other commonly used drugs are included.

Regarding the words ‘woman’ and ‘man’ in our texts
We write women/girls and men/boys in general in our texts. This is because the knowledge base in the database is based on studies where the population has been divided according to these categories. The knowledge database only covers studies on humans and studies that included individuals with the biological sexes woman and man (or girl and boy) because there is a lack of sufficient data to analyze non-binary gender identities.

Classification

All drug substances in Janusmed Sex and Gender are assigned to one of four classification categories. The classification is based on the amount of evidence for sex differences for the substance found in the literature searches.

Validation of scientific evidence regarding drugs and sex/gender

The information about drugs and sex/gender is based on structured literature searches in PubMed. The selection of articles for extensive review has been made according to the principles of evidence-based medicine. Thus, the knowledge compilation is based primarily on meta-analysis or well-done randomized clinical trials. When these are lacking, observational studies have been used.

Few studies are designed in order to directly study sex and gender differences in drug utilization. The information has therefore been collected from many different sources. Thus, a fair grading of evidence becomes difficult to implement, so we opted not to enter evidence level of this knowledge database Janusmed Sex and Gender. General levels of evidence grading applied by the Swedish Medical Products Agency (MPA), Swedish Agency for Health Technology Assessment and Assessment of Social Services (SBU), and The National Board of Health and Welfare are available on the agencies’ websites.

It is important to emphasize that the evidence grade not only depend on the study type, but also how well-done the study is. A well-designed observational study can provide a higher evidence grade that a bad (or too small) clinical trial. Generalizability to actual medical care is also higher in observational studies because patients participating in clinical trials often differ from those receiving the drug when it’s available on the market, due to clinical trials’ narrow inclusion and exclusion criteria.
