Pharmacology is an area of science which relates to the discovery, chemistry, composition, identification, biological and physical effects, uses and manufate of drugs. Pharmacology is commonly mistaken for pharmacy, which is a profession involving the preparation, and dispensing of drugs. Toxicology is a branch of biology, chemistry, and medicine concerned with the study of the adverse effects of chemicals on living organisms. It also studies the harmful effects of chemical, biological and physical agents in biological systems that establish the extent of damage in living organisms. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage; the route of exposure, the species, age, sex and environment.
