Thirty‐two children who had undergone liver transplantation were paired according to their post‐transplantation duration, renal function, and diagnoses when possible and randomized either to continue nifedipine (NIF group) or switch to diltiazem (DIL group), in addition to continuing their usual immunosuppressive medications. The cases were followed prospectively regarding diltiazem tolerance, cyclosporine dose requirements, effect on cyclosporine kinetics, diltiazem kinetics, as well as effect on renal function. Diltiazem was well tolerated at a dose of 3 mg to 6.4 mg/kg/day (max 180 mg/day) with infrequent self‐limited mild side effects. Cyclosporine daily dose was reduced by a mean of 36.7% and 38.3% at 3 and 6 months, respectively, in the DIL group to achieve target trough cyclosporine levels without modifying liver function. No significant difference in renal function was observed after 3 to 6 months in either group based on blood urea nitrogen and creatinine levels and glomerular filtration rate by the DTPA method. Diltiazem appears to be well tolerated in children and allows for substantial dose reductions of CSA without apparent effects on liver graft function.
