Modern advancements in pharmacology and toxicology have revealed that the rates and mechanisms by which organisms absorb, distribute, metabolize and eliminate chemicals-i.e., the field of kinetics-often determine the doses and conditions under which hazard, and harm, are absent, i.e., the safe dose range. Since kinetics, like chemical hazard ...Pharmacology and Toxicology .

Although pharmacology should also be on this list, it will be explained in the next part to better highlight the difference between pharmacology and pharmaceutical sciences. The no-observed-adverse-effect level (NOAEL) denotes the level of exposure of an organism, found by experiment or observation, at which there is no biologically or statistically significant increase in the frequency or severity of any adverse effects of the tested protocol. In drug development, the NOAEL of a new drug is assessed in laboratory animals, such …Toxicity vs. lethality: A drug is likely to be toxic, but not necessarily lethal, way before reaching LD50. So just because the dose you're giving isn't lethal that doesn't mean it's not toxic.It relies on the concept that a dose, or a time of exposure (to a chemical, drug, or toxic substance), will cause an effect (response) on the exposed organism. Usually, the larger or more intense the dose, the greater the response, or the effect. This is the meaning behind the statement “the dose makes the poison.”.
