Artificial intelligence is transforming clinical drug research by helping scientists analyze large datasets, improve clinical trial planning, and identify potential treatments more efficiently. AI-powered tools can support researchers in selecting suitable participants, monitoring trial progress, and detecting patterns that may not be easily recognized through traditional methods. While AI does not replace healthcare professionals or scientific expertise, it provides valuable insights that contribute to informed decision-making throughout the research process. As technology continues to advance, AI is expected to play an increasingly important role in improving the speed, accuracy, and overall quality of clinical drug research across various medical fields.
