Study Notes
Therapeutic Index
- The Therapeutic Index is a measure of the relative safety of a drug, describing the ratio of the dose that produces a toxic effect to the dose that produces a therapeutic effect.
- LD50 stands for Lethal Dose 50%, which is the dose of a drug that is lethal to 50% of the test population.
Calculating Therapeutic Index
- The formula for calculating the Therapeutic Index is: TI = LD50 / ED50, where ED50 is the Effective Dose 50%, which is the dose of a drug that produces a therapeutic effect in 50% of the test population.
