Due However, there are some conditions, such as arrhythmias or enlarged heart, where you would need to remain on calcium channel blockers (or another medication for that condition) indefinitely. Mechanism of Action: The mechanism by which nifedipine reduces arterial blood pressure involves peripheral arterial vasodilatation and, consequently, a reduction in peripheral vascular resistance.

If the initial glucose is less than 200 mg/dL, administer a bolus dose of glucose. In animal experiments, nimodipine had a greater effect on cerebral arteries than on arteries elsewhere in the body perhaps because it is highly lipophilic, allowing it to cross the blood-brain barrier; concentrations of nimodipine as high as 12.5 ng/mL have been detected in the cerebrospinal fluid of nimodipine-treated subarachnoid hemorrhage (SAH) patients.
