Specific contents and requirements of preclinical animal experiments
Preclinical animal experiment is a key link in the process of drug development, which provides an important basis for the evaluation of the safety and effectiveness of new drugs. The following are the specific contents and requirements of the experiment:
Content of 1. experiment
1. Drug safety assessment: observe the toxicity of drugs to animals, including acute toxicity, long-term toxicity, etc.
2. Pharmacodynamic verification: verify the pharmacological effects of drugs, such as dose dependence, mechanism of action, etc.
3. Drug metabolism research: study the absorption, distribution, metabolism and excretion of drugs in animals.
4. Drug-body interaction: Study the interaction between drugs and other drugs or food.
2. experimental requirements
1. Selection of experimental animals: select the appropriate animal breed, age, sex and health status according to the purpose of the experiment. Commonly used laboratory animals include rats, rabbits, dogs, etc.
2. Experimental design: to develop a detailed experimental program, including experimental purposes, methods, routes of administration, observation indicators. The experimental design should follow the principle of randomization, control and repetition.
3. Experimental operation specification: experimental operation should strictly abide by relevant regulations and guiding principles to ensure the accuracy and reliability of the experiment.
4. Ethics and welfare: to ensure the welfare and ethics of laboratory animals, to minimize the use and suffering of laboratory animals.
5. Data recording and analysis: detailed records of experimental data, including experimental phenomena, vital signs, blood biochemical indicators, etc. Statistical analysis of the experimental data leads to reliable conclusions.
6. Quality control: to ensure that the drugs, reagents and instruments used in the experiment meet the quality requirements and ensure the reliability of the experimental results.
7. Safety evaluation: multiple animal experiments are conducted at different stages of drug development to evaluate the safety of drugs under different conditions.
8. Report writing: Write detailed experimental reports, including experimental purposes, methods, results, conclusions, etc., to provide scientific basis for drug research and development decisions.
In conclusion, preclinical animal experiments are essential to ensure the safety and efficacy of drugs. The relevant regulations and guiding principles should be strictly observed during the experiment to ensure the accuracy and reliability of the experiment. At the same time, we should pay attention to the welfare and ethics of experimental animals, and minimize the use and suffering of experimental animals. The experimental results will provide an important basis for drug development decisions.
