The EMBASE database is a member of the Ovid EMBASE family that consists of three separate databases: Excerpta Medica Database (EMBASE), EMBASE Drugs and Pharmacology (EMDP), and EMBASE Psychiatry (EMPS). Formally, EMDP and EMPS are considered to be subsets of EMBASE. This field guide, although very similar in content to those of EMDP and EMPS, provides scope of information specific to the EMBASE database.
The Excerpta Medica database (EMBASE) produced by Elsevier Science, is a major biomedical and pharmaceutical database indexing over 3,500 international journals in the following fields: drug research, pharmacology, pharmaceutics, toxicology, clinical and experimental human medicine, health policy and management, public health, occupational health, environmental health, drug dependence and abuse, psychiatry, forensic medicine, and biomedical engineering/instrumentation. There is selective coverage for nursing, dentistry, veterinary medicine, psychology, and alternative medicine. EMBASE is one of the most widely used biomedical and pharmaceutical databases because of its currency and in-depth indexing. Frequent updates allow access to the latest medical and pharmacological trends. Approximately 375,000 records are added yearly.
The following alphabetical list provides the two-letter label, the relevant alias, and an example for each EMBASE field.

One of them is 6 weeks pregnant and the other is breastfeeding a 2-month-old infant, and I have received conflicting information about the safety of this drug during pregnancy and breastfeeding. What should I do? Answer: Although metronidazole has been on the market for almost 40 years, its use remains controversial during pregnancy and breastfeeding. Recent evidence has shown, however, that this drug is not associated with adverse effects during either pregnancy or breastfeeding.
