CONCLUSIONS 1. Drug Therapy for CVA patients were fluids resuscitation, neuroprotectan, vitamin, anti aggregation platelet, lipid lowering drug, antihypertensive, CHF, anti diabetic, drug for oedema, other tx for underlying diseases 2. Drug Tx were based patient’s clinical condition and lab data. Monitoring therapy is a must during hospitalization according to clinical & lab data 3. DRPs in this study were classified as need additional drug therapy, unneeded drug, wrong drug, side effects and potential drug interactions Dr Soetomo Teaching Hospital – Surabaya - Indonesia
