Phosphodiesterase inhibitors are also an option in calcium channel antagonist therapy. 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. Reports suggest that theuse of methylene blue, especially in those with amlodipine overdose resulting in vasodilatory shock, may be effective.
