Toxic Dose the dose at which toxicity occurs in 50% of cases. LD Lethal Dose the dose at which death occurs in 50% of cases. [6]: 73 [7] [8] TI Therapeutic Index a quantitative measurement of the relative safety of a drug by comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect [1]
