It is a comparison of the amount of a therapeutic agent that causes the therapeutic effect to the amount that causes toxicity. The related terms therapeutic window or safety window … Visa mer A high therapeutic index (TI) is preferable for a drug to have a favorable safety and efficacy profile. At the early discovery/development stage, the clinical TI of a drug candidate is unknown. However, … Visa mer Sometimes the term safety ratio is used, particularly when referring to psychoactive drugs used for non-therapeutic purposes, e.g. recreational use. In such cases, the effective dose is the amount and frequency that produces the desired effect, which can … Visa mer The protective index is a similar concept, except that it uses TD50 (median toxic dose) in place of LD50.
