Question about calcium channel blockers and ICP/CPP

I understand that CPP and ICP are very complicated, so please forgive my dummbassery. Since calcium channel blockers increase cerebral blood flow (by arterial dilation) but also decrease blood pressure, would they then increase cerebral perfusion pressure without the need for higher blood pressure? Similarly, would it increase ICP since increased cerebral blood flow would lead to more volume in the intracranial space?
