Study Notes
Medicines Discovery and Development Pathway
- Involves stages: Discovery, Development, and Post-marketing surveillance.
- Initial lead candidates are identified from thousands of compounds based on efficacy and safety.
- Adverse reactions can manifest around ~3 years in safety assessments, with complete insights potentially requiring ~8 years.
Benefit-Risk Ratio
- Critical concept in medicine development assessing the therapeutic benefit against potential risks and adverse drug reactions (ADRs).
- Evaluation hinges on efficacy and safety data throughout the developmental pipeline.
Key Terms Defined
- Adverse Drug Reaction (ADR): Unwanted effects that occur at therapeutic doses.
- On-target effects: Intended physiological effects achieved through drug interaction with its target.
- Off-target effects: Unintended interactions leading to adverse outcomes.
- Safety window: Range of doses where a drug is effective without causing significant ADRs.
Safety Assessment in Pre-Clinical Development
- Identifies high-risk compounds through regulatory Good Laboratory Practice (GLP) toxicology assessment.
- Continual dose escalation in animal studies evaluates safety and toxicity for different organs.
- Safety pharmacology assesses short-term effects on vital organs (CV, CNS, Respiratory) at therapeutic doses.
In Vivo Toxicology
- Long-term exposure in animal models used to capture ADRs at high doses.
- Emphasizes observation of side effects and post-mortem histology to identify tissue or organ risks.
Clinical Development Safety Protocols
- Trials Phase 1-4 focus on precise dosage, exclusion criteria, and monitoring for ADRs.
- Close observation for serious ADRs, with the power to suspend trials if safety risks outweigh benefits.
Key Players in Drug Development
- Collaboration among biomedical scientists, regulators, and clinical practitioners to ensure safety and efficacy.
- Continuous monitoring post-licensing through pharmacovigilance systems to ensure ongoing safety of medicines.
Importance of Patient Information
- Patient leaflets provide crucial dosing instructions and detail potential side effects.
- Encourages awareness and reporting of ADRs to promote safety.
Summary Insights
- All medications carry toxicity risks; safety is dependent on dosage established through rigorous testing.
- The interplay between on-target intended actions and off-target unintended actions creates uncertainties in ADR predictions.
- Collective effort from scientists, regulators, and healthcare professionals is essential in ensuring the safe delivery of new medicines to the public.
