In the case of reversible inhibitors being commonly applied in neurodegenerative disorders treatment, special attention is paid to currently approved drugs (donepezil, rivastigmine and galantamine) in the ...Toxicology Definition Toxicology Definition of toxicology is "the study of the adverse effects of chemicals or physical agents on living organisms The traditional definition of toxicology is "the science of poisons." As our understanding of how various agents can cause harm to humans and other organisms, a more descriptive definition of 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.”.

Characterisation of toxicity • Identify target organs • Dose dependence and relationship to exposure (toxicokinetics) Risk assessment • Safety margins between toxicology and efficacy studies • Monitorability and reversibility of the observed toxicity • Mechanism of toxicity – Relevance to humans – Relationship to pharmacologyBoth pharmacology and toxicology are scientific disciplines that focus on understanding the properties and actions of chemicals. However, pharmacology emphasizes the therapeutic effects of chemicals, usually drugs or compounds that could become drugs, whereas toxicology is the study of chemical's adverse effects and risk assessment. Definition 2: Margin of safety (MOS) is the ratio of no-observed-adverse-effect level (NOAEL) obtained from animal toxicology studies to the predicted, or estimated human exposure level or dose. It is equivalent to MOE. It is often used to assess the safety of cosmetic ingredients. For example, CFDA uses this appraoch.
