All patients were in a stable clinical condition. The mean maintenance dose was 9.1 \textasciitilde{}zg/kg (range 5 to 11 t\textasciitilde{}g/kg). Initially, daily maintenance dosage was given every 12 hours in equal doses. Blood sampling was performed in the patient's homes by finger or heel pricks; 0.5 to 0.8 ml was drawn from each sample. Assays were done in the therapeutic drug monitoring laboratory at The Hospital for Sick Children, Toronto, by the TDX method (Abbott Ltd., Mississauga, Ontario, Canada). The coefficient of variation of this test is less than 5\%. Heart rate, respiratory rate, and liver size were recorded at every visit before blood sampling was performed. In addition, the parents were asked to complete a daily diary, recording changes in the following: general health, behavior and sleeping patterns, appetite and feeding patterns, and gastrointestinal tract symptoms (anorexia, nausea, diarrhea). Parents could contact one of us, a pediatric cardiologist (E.Z.), 24 hours a day for report and consultation during the study.",
