Bioavailability生物利用度
Bioavailability is the fraction of an administered drug or active substance that reaches the systemic circulation in an unchanged form, together with the rate at which this occurs. In translation and localization, it appears in pharmacokinetic studies, product information, regulatory submissions, and labeling where absorption characteristics, absolute versus relative bioavailability, and factors affecting exposure are described.

Where this term appears
Bioavailability appears in pharmacokinetic study reports, clinical study protocols, summaries of product characteristics, and regulatory dossiers. Translators handle phrases such as absolute bioavailability, relative bioavailability, AUC, and Cmax, often in tables and statements comparing formulations, routes of administration, and the effect of food.
Translation checks
A common mistake is confusing bioavailability with bioequivalence or simple absorption. Bioavailability describes the fraction and rate at which a drug reaches the systemic circulation for a given product; bioequivalence compares two products. Interchanging these terms can change study conclusions, misstate labeling claims, and trigger regulatory queries.
Keep the term aligned across your files
Check intended use, warnings, document versions and approved terminology with the project team. Translation supports documentation; it does not establish product approval or regulatory acceptance.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
