Comparative effects of labetalol and bromazepam on ambulatory blood pressure of Nigerians with labile and stress hypertension.
|
| Abstract |
Twenty Nigerians with labile essential hypertension (LEH) were asked to record their blood pressure and pulse rate for 14-16 hours using the Remler Portable Ambulatory Blood Pressure Recorder while exposing themselves to the stress of Lagos traffic. The average blood pressure (systolic and diastolic) and pulse rate for the test day (ASBP, ADBP and APR) were determined in a cross-over randomised open design before (C), after one week on placebo bidaily (P1), after one week on bromazepam 1.5 mg bidaily (B), after one week on placebo bidaily (P2) and after one week on labetalol 100 mg bidaily (L). Allocation to the active drugs was randomised. All drugs were administered at 8.00a.m. and 8.00p.m. respectively. The maximum blood pressure (systolic and diastolic) and pulse rate MxSBP, MxDBP and MxPR were similarly determined. Both B and L significantly reduced ASBP, ADBP, APR, MxSBP, MxDBP and MxPR but L produced a much greater reduction in the above parameters than B. Side effects observed included drowsiness with B (two subjects) and postural dizziness with L (one subject). Both drugs were effective in controlling LEH but L was more effective than B in reducing stress hypertension.
