INTRODUCTION Statins and β1-adrenergic antagonists are well established in cardiovascular events therapy and prevention. The previous study showed that statins might impact on β-adrenergic signalling and blood pressure in a dose-dependent manner. The aim of the study was to evaluate the impact of 4-week administration of simvastatin given at different doses on the heart rate and blood pressure ...

A new, simple, precise, accurate and sensitive UV ‐ Spectrophotometric absorption correction method has been developed for simultaneous determination of Metoprolol Succinate and Olmesartan Medoxomil in combined tablet dosage form. Methanol was used as solvent. Absorbance correction method was based on the property of additivity of absorbances. The two wavelengths on Olmesartan medoxomil curve w...

BACKGROUND High value of neutrophil lymphocyte ratio (NLR) is a strong independent predictor and biomarker of ongoing vascular inflammation in various cardiovascular disorders. OBJECTIVE The main focus of the study is to investigate the effect of nebivolol on NLR in mild to moderate hypertensive patients in comparison with metoprolol. In addition, BMI, blood pressure, TLC count, blood sugar, ...

AIM AND BACKGROUND The present manuscript describes simple, sensitive, rapid, accurate, precise and economical spectrophotometric method for the simultaneous determination of telmisartan and metoprolol succinate in combined tablet dosage form. MATERIALS AND METHODS The method is based on the absorbance correction equations for analysis of both the drugs using methanol as solvent. Telmisartan ...

Over a 10-year period, 1993-2002, Federal Aviation Administration identified 50 pilot fatalities involving atenolol, metoprolol, and propranolol, which is consistent with the fact that these drugs have been in the lists of the top 200 drugs prescribed in the U.S. In a few of the 50 pilot fatality cases, initial analysis suggested the presence of atenolol and metoprolol. However, there was no me...

BACKGROUND Both metoprolol and carvedilol produce hemodynamic and clinical benefits in patients with chronic heart failure; carvedilol exerts greater antiadrenergic effects than metoprolol, but it is unknown whether this pharmacological difference results in hemodynamic and clinical differences between the 2 drugs. METHODS AND RESULTS We randomized 150 patients with heart failure (left ventri...

BACKGROUND One of the major problems in surgery is intraoperative bleeding which reduces visibility in the operative field. An important task for an anesthetist during head and neck surgery is to improve intraoperative visibility. OBJECTIVES The purpose of this study was to compare the amount of bleeding using different doses of oral metoprolol during three common types of nasal operation; rh...

A procedure for simultaneous determination of metoprolol and hydrochlorothiazide in tablets by employing derivative spectrophotometry, "zero-crossing" method was developed. The third order derivative absorption spectra at lambda approximately 281 nm were used for metoprolol and the first order derivative spectra at lambda approximately 282 nm were used for hydrochlorothiazide. No interferences ...

Endothelial dysfunction which is manifested by the loss of nitric oxide bioavailability, is an increasingly recognized cause of cardiac syndrome X (CSX) and beta blockers are used for the treatment of this syndrome. Thus, the aim of this study was to investigate effects of metoprolol, as a beta blocker, on endothelial function in CSX patients. The study included 25 CSX patients (20 female/ 5 ma...

OBJECTIVES This study sought to compare the effects of metoprolol and carvedilol in the MADIT-CRT (Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy) study. BACKGROUND The impact of beta-blockers in heart failure (HF) patients with devices is uninvestigated. METHODS All patients receiving either metoprolol or carvedilol in the MADIT-CRT study were...
