This trial will be a phase 2 randomized safety study in which ischemic stroke patients will be randomly assigned within 24 hours of symptom onset to placebo or standard dose lovastatin versus short-term high-dose lovastatin 640 mg per day for 3 days. The primary outcome of this Phase 2 study will be musculoskeletal and hepatic toxicity, defined by clinical and laboratory criteria, with a 3-month follow-up period (± 1 week). Secondary outcomes will include neurological outcome (National Institute of Health (NIH) Stroke Scale), functional outcomes (Barthel Index), and handicap (modified Rankin scores). Effects on inflammatory markers and lipid levels will also be assessed.
