AI in Drug Discovery: Revolutionizing Medicine Future

AI in Drug Discovery: Revolutionizing Medicine Future

The pharmaceutical industry is at the cusp of various changes due to AI in drug discovery, which provides game-changing opportunities to speed up the process, save money and increase efficacy. Current drug discovery is a costly and protracted process that can take over 10–15 years and cost over $2.5 billion per successful drug. AI in drug discovery enables scientists to study those huge datasets of biology, predict drug-drug interactions and generate novel compounds orders of magnitudes faster than before.

By 2024, AI in drug discovery is already doing:

• Faster identification of promising drug candidates (reducing discovery time from years to months)
• More precise target selection using deep learning and genomic analysis
• Clinical trials showing higher success rates with predicting efficacy and toxicity early in the trial
