How does this medication work?
Nimodipine, Nimotop/Nymalize blocks calcium channels in smooth muscle of the blood vessels which relaxes them causing them to dilate which reduces vascular resistance thereby lowering blood pressure and increasing blood flow in areas such as the heart and limbs. Animal studies indicate that nimodipine has a greater effect on cerebral arterials than other arterials; this increased specificity may be due to the drug’s increased lipophilicity and cerebral distribution as compared to nifedipine.
How should I take this medication?
Oral: 60 mg every 4 hours for 21 consecutive days. Start therapy within 96 hours of the onset of subarachnoid hemorrhage
