High chemotherapeutic index
The therapeutic index (TI; also referred to as therapeutic ratio) is a quantitative measurement of the relative safety of a drug. It is a comparison of the amount of a therapeutic agent that causes the therapeutic effect to the amount that causes toxicity.

At the early discovery/development stage, the clinical TI of a drug candidate is unknown. However, … Ver mais A therapeutic index does not consider drug interactions or synergistic effects. For example, the risk associated with benzodiazepines increases significantly when taken with … Ver mais The protective index is a similar concept, except that it uses TD50 (median toxic dose) in place of LD50. For many substances, toxic effects can occur at levels far below those needed to cause death, and thus the protective index (if toxicity is properly … Ver mais The therapeutic index varies widely among substances, even within a related group. For instance, the opioid painkiller remifentanil is … Ver mais 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 vary, and … Ver mais The therapeutic window (or pharmaceutical window) of a drug is the range of drug dosages which can treat disease effectively … Ver mais Optimal biological dose (OBD) is the quantity of a drug that will most effectively produce the desired effect while remaining in the range of acceptable toxicity.
