Prediction of Drug-Receptor Binding Inside the Spinal Cord Tissue Prediction of morphine binding to receptors based on clinical data Image of the spinal cord Drug Dispersion Drug Action Collaborator: Jaimie Stewart
Eliminating the ‘Unpredictability’ of intrathecal drug spread Stienstra & Greene, 1991
Intrathecal Infusion Predictive Model • Test infusion on virtual patient • Optimize dosage • Assess potential toxicity • Predict drug dispersion a priori
Summary • 3D computational spine model is ready for simulation • Learned from 2D qualitative model • We expect 3D model to be quantitative • Facing the challenge in predicting IT spread • Predict drug dispersion pattern • Coupling transport with receptor binding • Predict drug action & therapeutic effect • Validation with clinical measurements every step
