What are the 4 phases of a clinical trial? Safety, Dosage, Efficacy, Post-Marketing Surveillance
Clinical trials are crucial in the development of new medications, offering the opportunity to assess their safety, efficacy, and side effects. These trials are conducted in distinct phases, each serving a specific purpose and contributing to the overall understanding of a drug's potential. In this comprehensive guide, we will explore the main phases of clinical trials and their significance in the drug development process. From Phase 1, focusing on safety and dosage determination, to Phase 2, evaluating preliminary efficacy and side effects, and finally Phase 3, confirming efficacy and safety, we will delve into the critical aspects of each phase. Additionally, we will discuss Phase 4 trials, which monitor the drug's long-term effects post-approval.
