GCSE Biology - Drug Development and Testing - Clinical Trials #45

The video explains the development and testing of drugs, highlighting the use of natural substances from microorganisms and plants. It provides examples like aspirin, digitalis, and penicillin, detailing their origins. The drug testing process is outlined, focusing on efficacy, toxicity, and dosage. The stages of preclinical and clinical testing are discussed, emphasizing the importance of blind trials, placebos, and peer review to ensure fairness and validity in scientific research.

Which natural source was Aspirin originally derived from?

• Willow trees

• Foxgloves

• Penicillium fungus
