Pharmacology vs. Toxicology. Pharmacology Potency refers to the relative amount of a drug required to produce the desired response. Toxicology The toxicity of a chemical refers to the relative amount it takes to elicit a toxic effect compared with other chemicals.Credit: iStock. Pharmacology is the study of how molecules, such as medicines, interact with the body. Scientists who study pharmacology are called pharmacologists, and they explore the chemical properties, biological effects, and therapeutic uses of medicines and other molecules. Their work can be broken down into two main areas:In pharmacology and toxicology, "saturation" refers to a state in which the concentration of chemical exceeds the concentration of metabolizing enzymes present in the system (Andersen 1981). At dosages that produce a saturated state, the rate at which chemicals are metabolized and/or eliminated will be altered compared to lower dosages.

Pharmacology vs toxicology, 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 ..., The median toxic dose is the dose required to produce a defined toxic effect in 50% of subjects. The median lethal dose is the dose required to kill 50% of subjects. The therapeutic index is the ratio of the TD 50 to the ED 50 , a parameter which reflects the selectivity of a drug to elicit a desired effect rather than toxicity., Pharmacology is a science of medical drug and medication, including a substance's origin, composition, pharmacokinetics, therapeutic use, and toxicology., Pharmacodynamics is a division of biochemical pharmacology which defines the relationship between plasma and tissue drug and metabolite concentrations, time, and biological response.

It is defined as the plasma volume that can be completely cleared of the drug in a given period of time (e.g., creatinine clearance ). CL = Vd x Ke = rate of drug elimination/plasma drug concentration. Vd = volume of distribution., Local anaesthetic drugs are water-soluble salts of lipid-soluble alkaloids. The structure of local anaesthetics consists of three components: a lipophilic aromatic group, an intermediary link and a hydrophilic amine group ( Fig. 2 ). The intermediary link categorises local anaesthetics into esters or amides ( Table 1 )., Applications of Causal Inference in Toxicology . In toxicology, the test agent is given to the animal or in vitro cellular system under clearly defined exposure conditions (e.g., oral, dermal, inhalation; gavage, diet; short term, long term, etc.).
