INDICATIONS AND USAGE: NYMALIZE is a dihydropyridine calcium channel blocker indicated for the improvement of neurological outcome by reducing the incidence and severity of ischemic deficits in adult patients with subarachnoid hemorrhage (SAH) from ruptured intracranial berry aneurysms regardless of their post-ictus neurological condition (i.e., Hunt and Hess Grades I-V). A single copy of these materials may be reprinted for noncommercial personal use only. Progressive deterioration reverses this trend, and patients with severe renal failure (creatinine clearance < 10 mL/min) who have been on hemodialysis show a 20% - 50% lower AUC than healthy volunteers. That means when calcium ions enter a cell, sodium ions leave, and vice versa. Maximum antihypertensive effect is seen by 14 days.
