Treatments
Of the 345 patients randomized, 120 were randomized to enalapril
20 mg, 110 to lercanidipine 10 mg and 115 to enalapril/lercanidipine
20/10 mg fixed combination once a day for 24 months.
Enalapril, lercanidipine and enalapril/lercanidipine fixed combination
were supplied as identical, opaque, white capsules in coded
bottles to ensure the blind status of the study. Randomization was
carried out using a draw of envelopes containing randomization
codes prepared by a statistician. Medication compliance was
assessed by counting the number of pills returned at the time of
specified clinic visits. Throughout the study, we instructed patients
to take their first dose of new medication on the day after they
were given the study medication. At the same time, all unused
medication was retrieved for inventory. All medications were
provided free of charge.
