Thirty-one patients aged 65 y or over suffering from moderate hypertension were studied for 16 weeks using a cross-over design in which metoprolol 100 mg daily and metoprolol 200 mg daily were compared. Both treatment regimes were effective in controlling hypertension and no difference was found between the two with regard to efficacy. The 100 mg regime was, however, better tolerated and we pro...

BACKGROUND Currently, no pharmacological treatment can modify the natural history of aortic valve stenosis (AS). This underlines the critical need to explore novel treatment strategies, which could postpone or prevent the need for aortic valve replacement in patients with asymptomatic AS. The objectives of this study were to investigate whether metoprolol reduce the hemodynamic and metabolic bu...

BACKGROUND Metoprolol treatment is well established for chronic heart failure (CHF) patients, but the central nervous system side effects are often a potential drawback. OBJECTIVE To investigate the impact of metoprolol treatment on change in mental status of CHF patients with clinical psychological disorders (such as depression, anxiety, and burnout syndrome). METHODS From February 2013 to...

BACKGROUND β-Blockers exert a prognostic benefit in the treatment of chronic heart failure. Their pharmacological properties vary. The only substantial comparative trial to date-the Carvedilol or Metoprolol European Trial-has compared carvedilol with short-acting metoprolol tartrate at different dose equivalents. We therefore addressed the relative efficacy of equal doses of carvedilol and meto...

BACKGROUND The effect of beta-blockade on the cardiac natriuretic peptides is poorly understood but could contribute to their beneficial treatment effect and may be relevant to clinical use of plasma brain natriuretic peptide (BNP)/N-terminal pro brain natriuretic peptide (NTproBNP) measurements in risk stratification and in titration of anti-heart failure therapy. METHODS AND RESULTS Sixteen...

BACKGROUND Non-selective and selective beta-blockers have been shown to improve outcomes in chronic heart failure (CHF). Recent data suggests the non-selective beta-blockers have a more favourable effect on outcomes than beta(1)-selective agents. We sought to examine the differential effects of non-selective versus selective beta-blockade on myocardial substrate utilization in patients with CHF...

OBJECTIVES The aim of this study was to investigate whether nebivolol has added effects on left ventricular (LV) dysfunction and remodeling early after myocardial infarction (MI) beyond its β₁-receptor-blocking properties. BACKGROUND Nebivolol is a third-generation selective β₁-adrenoreceptor antagonist that stimulates endothelial cell nitric oxide (NO) production and prevents vascular reduce...

The present work describes a two-wavelength method for simultaneous determination of metoprolol and hydrochlorthiazide in fixed dose combination tablet. The wavelengths selected for method were 257.8 nm, 282.9 nm and 315.0 nm. The absorbance difference at first two wavelengths was used for determination of metoprolol and the latter was used for determination of hydrochlorthiazide. The recovery ...

and the mean observed peak plasma metoprolol concentration by about 33%. Furthermore, the elimination half life of metoprolol was prolonged from 3-9 hours during monotreatment to 6-0 hours when ranitidine was given in combination (p<0005). There was no evidence that any of the volunteers were poor metabolisers of metoprolol. Beta-blockade was assessed on the sixth treatment day by examining the...

This study examined the influence of preoperative administration of amiodarone and metoprolol in preventing postoperative atrial fibrillation (AF) after coronary artery bypass grafting (CABG) surgery.The study comprised 251 patients who underwent CABG surgery at our hospital between January 2012 and May 2014. The patients were randomly divided into 2 groups: amiodarone therapy group (n = 122 pa...
