Therapeutic ratio radiation therapy
The therapeutic ratio in radiotherapy for cancer treatment is determined by the maximum radiation dose for killing cancer cells and the minimum radiation dose causing acute or late morbidity in cells of normal tissues. Both of these parameters have sigmoidal dose-response curves. Visa mer 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 … Visa mer Sometimes the term safety ratio is used, particularly when referring to psychoactive drugs used for non-therapeutic purposes, e.g. recreational use. … Visa mer 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 … 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 … Visa mer The therapeutic index varies widely among substances, even within a related group. For instance, the opioid painkiller remifentanil is … Visa mer A therapeutic index does not consider drug interactions or synergistic effects. For example, the risk associated with benzodiazepines increases significantly when taken with alcohol, opiates, or stimulants when compared with being taken alone. … Visa mer The therapeutic window (or pharmaceutical window) of a drug is the range of drug dosages which can treat disease effectively … Visa mer Webb25 feb. 2024 · Recent advances in mesenchymal stem/stromal cell (MSC) research have led us to consider the feasibility of MSC-based therapy for various diseases.
