Researchers have recently introduced an innovative machine learning approach to predict accurate drug interactions. By utilizing tissue models and advanced algorithms, they have developed a method that can identify potential drug interactions, significantly enhancing patient safety and treatment efficacy.
Traditionally, understanding how drugs work in the human digestive tract, with its complex system, has been a challenge. Drugs administered orally must navigate various pathways to be effectively absorbed. Transporter proteins lining the gastrointestinal tract play a crucial role in facilitating the passage of drugs into the bloodstream. However, identifying which transporters individual drugs utilize has long eluded pharmacologists.
Lead author Giovanni Traverso, an associate professor at MIT and gastroenterologist at Brigham and Women’s Hospital, explains the dilemma by stating, “One of the challenges in modeling absorption is that drugs are subject to different transporters.” But now, with the unveiling of this new approach, researchers can uncover transporter-drug interactions and pinpoint potential medication conflicts that could harm treatment outcomes.
The team’s methodology involves a two-pronged strategy. Firstly, they employ tissue models developed in 2020 to simulate drug absorption in the lab. By selectively inhibiting specific transporters using short RNA strands, researchers gain insight into the roles of individual transporters in drug absorption pathways, shedding light on drug transport mechanisms across the gastrointestinal tract.
Secondly, the researchers harness machine learning algorithms that have been trained on experimental data and drug databases to predict potential drug interactions. By analyzing chemical similarities between drugs, the model accurately forecasts interactions with specific transporters. This capability allows for the screening of both existing and experimental drugs, ultimately improving the understanding of drug safety implications.
Through this groundbreaking approach, researchers have identified previously unrecognized drug interactions, such as the interaction between the antibiotic doxycycline and the blood thinner warfarin. By analyzing patient records, it was confirmed that co-administration of these drugs caused fluctuations in warfarin levels in the bloodstream. Moreover, interactions between doxycycline and other medications such as digoxin, levetiracetam, and tacrolimus were also detected.
Traverso emphasizes the importance of this approach, stating that it “gives you the ability to understand the potential safety implications of giving these drugs together.” Not only does this method enhance the safety of existing drug combinations, but it also holds promise for optimizing the development of new drugs.
Looking ahead, researchers aim to further enhance the safety and effectiveness of future medications by fine-tuning drug formulations to minimize interactions or enhance absorption. Vivtex, a biotech company co-founded by MIT researchers, is currently leading the application of this technology to develop innovative oral drug delivery systems.
The integration of tissue models and machine learning algorithms offers a powerful tool for predicting drug interactions and optimizing patient treatment. With continued refinement and application, this groundbreaking approach has the potential to revolutionize drug safety and pave the way for more advanced pharmaceutical therapies.
