RESULTS The global antihypertensive activity of ARB differs from that observed with amlodipine in the sense that the magnitude of the reduction in the BP values does not essentially depend on the initial BP values nor on the dose used .
When only ARB were considered , the drug used was a determinant for systolic BP reduction , whereas for diastolic BP the influence was on the BP reduction and the duration of the antihypertensive activity .
The dose used had a particular influence on the duration of the antihypertensive activity for both systolic and diastolic BP .
CONCLUSION Among the ARB , the influence is on duration more than on the magnitude of BP reduction .
Dose , therefore , is an important factor in the duration of antihypertensive activity
OBJECTIVE To perform a systematic review of the antihypertensive activity of the angiotensin II AT1 receptor antagonists ( ARB ) .
Comparison of the smoothness index, the trough: peak ratio and the morning evening ratio in assessing the features of the antihypertensive drug effect
Objective To provide a direct comparison of the trough : peak ratio ( TPR ) , the morning : evening home blood pressure ratio ( MER ) and the smoothness index ( SI ) in assessing the features of the antihypertensive drug effect . Patients and methods A total of 27 untreated hypertensives were r and omized to receive lisinopril 20 mg o.d . or losartan 50 mg o.d . for 5 weeks and were subsequently crossed-over to the alternative treatment for a second 5-week period . Twenty-four hour ambulatory and 5-day home blood pressure were monitored before r and omization and at the end of each treatment period . TPR , MER and SI were calculated for each drug for the total study population and for responders only . Results When all patients were considered , lisinopril provided higher values of TPR [ 0.63/0.66 for systolic/diastolic blood pressure ( SBP/DBP ) ] , MER ( 1.02/0.77 ) and SI ( 1.01/0.87 ) than losartan ( 0.35/0.51 , 0.60/0.60 and 0.64/0.53 , respectively ) . Analysis of responders only , again showed a clear advantage of lisinopril over losartan in TPR ( 0.77/0.67 versus 0.44/0.47 , respectively ) and MER ( 0.86/0.87 versus 0.48/0.61 ) , whereas there was no difference in SI ( 1.25/1.13 for lisinopril versus 1.11/1.12 for losartan ) . Conclusions These data suggest that the assessment of the duration of the antihypertensive drug effect provided by the MER is consistent to that by the TPR and that two drugs with different levels of TPR and MER may have the same level of SI . It appears that the SI is not simply a more reliable index of the features of the antihypertensive drug effect , but offers a different type of information complementary to that provided by the TPR and the MER , in regard to the homogeneity and the magnitude but not the duration of the antihypertensive effect
