What is General Toxicology Evaluation?
General toxicity evaluation refers to the ability of a drug to produce an overall toxic effect on the experimental animal body at a certain dose, a certain contact time, and a certain contact method. General toxicity evaluation is the basis for safety assessment and is crucial for drug efficacy research. General toxicity evaluation includes acute, sub-acute, sub-chronic, and chronic toxicity evaluation.
Acute Toxicity Evaluation
Acute toxicity evaluation refers to a test involving one or multiple exposures within 24 hours and is the first step in toxicity research. It is required to use rodent or non-rodent animals.
Sub-acute Toxicity Evaluation
Sub-acute toxicity evaluation refers to the short exposure period, usually 3 months, or the short-term exposure to the poison that causes functional and/or structural damage to the body.
Sub-chronic Toxicity Evaluation
Sub-chronic toxicity evaluation refers to the toxic effects that occur when experimental animals are exposed to larger doses of drugs for many consecutive days.
Chronic Toxicity Evaluation
Chronic toxicity evaluation refers to the toxicity of a drug after long-term low-dose effects in the body. The study period is generally greater than 6 months.
How Is General Toxicology Evaluation Performed?
General toxicity evaluation is generally conducted on experimental animals. The species of non-clinical experimental animals are divided into rodents (rats, mice, guinea pigs, rabbits) and non-rodents (dogs, monkeys). Different administration routes and dosages can be set, and toxicity studies can be conducted by observing physiological, hematological, physiological, biochemical, and pathological indicators. In addition, a combination of in vivo and in vitro toxicity evaluation can be used to conduct a more comprehensive evaluation of drug toxicity.
