SBP-lowering effects were significantly increased for bisoprolol compared with placebo .
In conclusion , current evidence does not support carvedilol or bisoprolol as first-line therapy for adult hypertension without compelling indications
Although beta blockers have been used as initial therapy for ischemic heart diseases and heart failure , the beneficial effects of beta blockers are controversial compared with other antihypertensive agents as initial therapy for hypertension without compelling indications .
Moreover , atenolol has been most commonly used with beta blockers .
The objective of the present systematic review associated with the Japanese Society of Hypertension ( JSH ) 2019 Hypertension Guideline ( Clinical Question 6 ) was to assess the outcomes ( cardiocerebrovascular mortality , total cause mortality , hypotension , bradycardia , other adverse effects , and changes in systolic blood pressure ( SBP ) ) of currently used carvedilol and bisoprolol as initial therapy for adult hypertension without compelling indications .
Double-blind, placebo-controlled crossover comparison of five classes of antihypertensive drugs
Objective Hypertension guidelines recommend initial treatment with a β-blocker or diuretic and adding the other drug where blood pressure is not controlled . We hypothesized that systematic rotation through the major classes of antihypertensive drugs would demonstrate substantial differences in the pattern of an individual patient 's response , and suggest a more rational approach to choosing best treatment . Design Thirty-four young hypertensives ( age 28–55 , median 47 ) rotated in a double-blind , Latin-square , crossover fashion through 6 weeks of treatment each with amlodipine , doxazosin , lisinopril , bisoprolol , bendrofluazide and placebo . Blood pressure was measured at each visit . ‘ Best ’ drug , defined by efficacy and tolerability , was repeated at the end . Results Rotation doubled the number of patients reaching target blood pressure ( systolic < 140 mmHg ) on one drug ( P = 0.03 ) . All five drugs were represented among the ‘ best ’ drugs . In six patients , the blood pressure on ‘ best ’ drug was at least 10 mmHg lower than on any other . Response to the ‘ best ’ drug was highly correlated ( r = 0.79 ) with its previous administration . By contrast , there were only weak correlations between responses to pairs of drugs , except for angiotensin-converting enzyme ( ACE ) inhibitor ( A ) with β-blocker ( B ) , and calcium blocker ( C ) with diuretic ( D ) – each r = 0.71 , P < 0.005 ) . In these young patients , the majority of patients ( 23/34 ) responded best to a drug suppressing the renin system ( A and B ) . Conclusions Patients vary reproducibly in their response to initial treatment , and switching among drugs can increase the efficacy of monotherapy . The results support an AB/CD scheme for choosing therapy , in which the first drug is taken from one of these pairs , and uncontrolled patients switch to one of the other pair
