title: Isradipine for the prevention of cyclosporine-induced hypertension in allogeneic bone marrow transplant recipients: a randomized, double-blind study.
abstract: BACKGROUND
  Hypertension and nephrotoxicity frequently occur in patients who receive cyclosporine therapy after bone marrow transplantation (BMT). Isradipine, a calcium channel entry blocker, has been used successfully in cyclosporine-induced hypertension.
  
  
  METHODS
  Thirty leukemic patients who received cyclosporine after BMT were randomized to receive isradipine (0.005 mg/kg) from 72 hr before commencement of cyclosporine therapy until day 100 after BMT or placebo.
  
  
  RESULTS
  The placebo and isradipine groups were well matched. No differences were found between the isradipine and placebo groups in the level of blood pressure, renal function, marrow engraftment, or mortality. Hypertension incidence was surprisingly low (30% a week after hospital discharge and 10% by day 100 after BMT), and did not differ between the groups.
  
  
  CONCLUSIONS
  Isradipine does not harm immunohematopoietic reconstitution after BMT; therefore, it may be used in this setting, although the previously reported incidence of hypertension has been exaggerated.
