American Nimodipine Study "ANS"


Phase 3 Results


No difference in mortality or neurological outcome was found with any of the rating scales for the overall cohort. Planned but post hoc subgroup analysis showed a reduction in worsening frequency of 30% compared with placebo and significantly better outcome scores with 120 mg nimodipine daily started within 18 hours of stroke as measured by the Toronto scale (p less than 0.005) and when the pretreatment computed tomographic scan was negative (p less than 0.003).
