The effect of the diltiazem-cyclosporine interaction on cyclosporine pharmacokinetics, pharmacodynamics, and pharmacoeconomics was studied in 10 recipients of renal allografts. Each subject was studied while receiving diltiazem 60 mg twice/day and while not taking the drug. After achieving steady-state conditions, cyclosporine and metabolite concentrations were determined in whole blood from samples drawn after the morning cyclosporine dose. After pharmacokinetic analysis, all patients were followed for 6 months during treatment with cyclosporine plus diltiazem or cyclosporine alone. Cyclosporine blood clearance decreased significantly after treatment with diltiazem (18.0-11.0 ml/min.kg; p = 0.008). The apparent volume of cyclosporine distribution also decreased significantly (4.26-2.62 L/kg; p0.05). After 6 months, diltiazem had no effect on renal function indexes, and no apparent effect on immunosuppression. Alterations in cyclosporine clearance and apparent volume of distribution secondary to diltiazem result in dosage reduction and potential cost savings in transplant pharmacotherapy. The mean decrease in cyclosporine dosage requirements would produce a cost saving of $1520 or 28% per patient per year. |
