    GlossaryOral Bioavailability

    proportion of a substance absorbed into the bloodstream when ingested

    Oral bioavailability refers to the proportion of a drug or substance that enters the bloodstream when it is taken by mouth and becomes available for use or storage in the body. It is a critical factor in determining the correct dosage for medications, as it affects how much of the active ingredient actually reaches the target tissues.
