By discovering and creating novel drugs to treat a range of illnesses, the discipline of drug discovery and development plays a vital role in healthcare. Conventional approaches to drug development have been costly, time-consuming, and frequently produce drugs that don't work for every patient. Precision medicine, on the other hand, seeks to customize medical care to each patient's unique needs while accounting for lifestyle, environment, and genetics. Artificial Intelligence (AI) has revolutionized drug discovery and development in recent years when it has become a potent instrument. Machine learning and deep learning are two examples of AI technologies that could drastically speed up medication discovery, lower prices, and increase treatment efficacy. Researchers can find possible therapeutic targets, create new compounds, and forecast patient response to treatment with the use of artificial intelligence (AI), which analyzes vast datasets and find patterns. This research investigates how AI can be used to find and produce drugs for precision medicine. With adding that, it gives a summary of the conventional drug discovery procedure, emphasizing its drawbacks. Later this research describes how AI technologies are being applied to solve these obstacles, with particular attention to how they are being employed in clinical trials, target identification and validation, and computational drug design. The research also looks at how AI may help to provide personalized medicine, i...
