Repurposing existing drugs: AI-driven drug repurposing platforms analyze large datasets of drug compounds and biological targets to identify new therapeutic uses for existing drugs. By leveraging existing safety and pharmacokinetic data, AI accelerates the identification of potential drug candidates for repurposing, reducing the time and costs associated with traditional drug discovery.¹⁶

Medication optimization

Personalized Medicine: AI algorithms analyze various patient data, including medical history, genetic information, lifestyle factors, and treatment outcomes, to create individualized medication regimens tailored to each patient's unique characteristics. By considering a patient's genetic predispositions and physiological responses to medications, AI can optimize treatment plans for better efficacy and reduced side effects.¹⁷ Predictive Modeling: AI can predict how patients are likely to respond to different medications and dosages based on their demographic information, medical history, genetic profile, and other relevant factors. By analyzing large datasets of patient outcomes, AI algorithms identify patterns and correlations that help predict the most effective treatment options for specific patient populations.¹⁸ Optimization of Dosages: AI-powered systems can optimize medication dosages based on factors such as age, weight, kidney function, liver function, drug interactions, and genetic variations in drug metabolism pathways.¹⁹ By considering these factors, AI can recommend personalized dosing regimens that maximize therapeutic benefits while minimizing the risk of adverse reactions or toxicity.²⁰

Real-Time Monitoring: AI-enabled monitoring systems can track patient responses to medications in real time, using data from wearable devices, electronic health records, and other sources. By continuously analyzing patient data, AI algorithms can adjust medication regimens as needed to optimize outcomes and prevent complications.^{21 22}

Clinical Decision Support: AI-based clinical decision support tools provide healthcare providers with real-time recommendations and alerts regarding medication selection, dosing, monitoring, and adjustments. By integrating with electronic health records and other clinical systems, AI helps clinicians make more informed decisions about medication therapy, leading to improved patient outcomes and safety.²³

Clinical decision support

Real-time Insights: AI-based CDS tools continuously analyze patient data, including medical history, lab results, medication records, and diagnostic information, to provide clinicians and pharmacists with real-time insights into patient care. By processing large volumes of data quickly and accurately, AI helps healthcare providers make informed decisions about medication therapy and treatment plans.²⁴ Medication Therapy: AI-based CDS systems help clinicians and pharmacists select the most appropriate medications for individual patients based on their medical conditions, allergies, comorbidities, and other relevant factors. These systems can recommend evidence-based treatment guidelines, drug formularies, and alternative therapies to optimize medication therapy and improve patient outcomes.²⁵ Drug Interactions: AI algorithms analyze medication lists and patient data to identify potential drug-drug interactions, contraindications, and adverse reactions.²⁶ By flagging potential risks and providing recommendations for alternative medications or dosage adjustments, AI-based CDS tools help prevent medication errors and adverse drug events.¹ Adverse Reactions: AI-powered CDS systems can detect early signs of adverse drug reactions and alert healthcare providers to potential safety concerns.²⁷ By monitoring patient responses to medications and

Correlating symptoms with drug exposures, AI helps clinicians and pharmacists intervene promptly to mitigate risks and ensure patient safety.²⁸ Clinical Guidelines Compliance: AI-based CDS tools help healthcare providers adhere to evidence-based clinical guidelines and best practices by integrating clinical decision rules, treatment protocols, and quality measures into their workflow.²⁹ By aligning care delivery with established standards, AI improves the consistency and quality of patient care across healthcare settings.³⁰ Efficiency and Workflow Integration: AI-powered CDS systems seamlessly integrate into existing clinical workflows, electronic health record systems, and pharmacy management systems, providing clinicians and pharmacists with actionable insights and recommendations at the point of care.
