Bioavailability index
WebIt is also targeted for drugs with unpredictable pharmacokinetic-pharmacodynamic relationships with dose as well as drugs with a narrow therapeutic index. Slide 4: Therapeutic Index. The therapeutic index is the ratio between the toxic dose in 50% of subjects and the therapeutic dose of a drug that is effective in 50% of patients. WebBioavailability (F) is defined as the rate and extent to which the active constituent or active moiety of a drug is absorbed from a drug product and reaches the circulation.
