  Patients who undergo mechanical heart valve replacements or have conditions
like Atrial Fibrillation have to take Vitamin K Antagonists (VKA) drugs to
prevent coagulation of blood. These drugs have narrow therapeutic range and
need to be very closely monitored due to life threatening side effects. The
dosage of VKA drug is determined and revised by a physician based on
Prothrombin Time - International Normalised Ratio (PT-INR) value obtained
through a blood test. Our work aimed at predicting the maintenance dosage of
warfarin, the present most widely recommended anticoagulant drug, using the
de-identified medical data collected from 109 patients from Kerala. A Support
Vector Machine (SVM) Regression model was built to predict the maintenance
dosage of warfarin, for patients who have been undergoing treatment from a
physician and have reached stable INR values between 2.0 and 4.0.
