Assignment to a toxicity class is based typically on results of acute toxicity studies such as the determination of LD 50 values in animal experiments, notably rodents, via oral, inhaled, or external application. The experimental design measures the acute death rate of an agent.
The high levels of testosterone in males are why hematocrit and hemoglobin levels are higher in men than in women. [125] Due to stimulation of erythropoiesis, anabolic–androgenic steroids (AAS) such as oxymetholone and nandrolone decanoate are effective for and used in the treatment of severe anemia (very low hematocrit).
In addition, toxicity categories may be used for regulatory purposes other than labeling, such as classification for restricted use and requirements for child-resistant packaging. In certain cases, statements based upon the Toxicity Category of the product as diluted for use are also permitted. A Toxicity Category is assigned for each of five ...
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]

The median toxic dose encompasses the category of toxicity that is greater than half maximum effective concentration (ED 50) but less than the median lethal dose (LD 50). However, for some highly potent toxins (ex. lofentanil , botulinum toxin ) the difference between the ED 50 and TD 50 is so minute that the values assigned to them may be ...
