[Fasting and postprandial lipids and lipoproteins during the chronic administration of antihypertensive drugs].
To evaluate the effect of various antihypertensive drugs on fasting and postprandial lipids and lipoproteins, we studied 39 normolipidemic hypertensive patients, 28 men and 11 women aged 52.3 +/- 9.0 and 58.5 +/- 7 years, respectively. After four weeks of placebo administration, lipids and lipoproteins were measured in the fasting state and every three hours for a period of nine hours after intake of a standardized fat mixed load (65 g/m2). Following this test, the patients were randomly assigned to one of four treatment groups: group I metoprolol (n = 10), 100 mg/day; group II nicardipine (n = 9), 90 mg/day; group III captopril (n = 11), 75 mg/day. At the end of week four of treatment the fasting and postprandial lipid measurements were repeated. Blood pressure mean values were significantly (p < 0.05) reduced in the four treatment groups. We found no statistically significant lipids or lipoproteins changes neither in the fasting nor in the postprandial state, but a trend toward lower concentrations in the postprandial lipemia after treatment was observed in three groups (metoprolol, nicardipine and captopril), whereas no change was observed in the chlorthalidone group. These data confirm that fasting lipids and lipoproteins in normolipidemic hypertensive patients are not unfavorably changed by low doses of the drugs studied. In addition, we inform that postprandial lipemia is not affected by these four drugs in the doses used.
