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; rhin...
Background: β-Blockers have shown considerable cytotoxic, anti-tumor and anti-angiogenic effects. Metoprolol, a β-Blocker with anti-inflammation, anti-tumor and anti-angiogenic properties has been widely used for treatment of some cardiovascular diseases such as angina, hypertension, heart failure and myocardial infraction. Limited data exist about the cytotoxic effects of metoprolol on human c...
BACKGROUND Carvedilol has been shown to be superior to metoprolol tartrate to improve clinical outcomes in patients with heart failure (HF), yet the mechanisms responsible for these differences remain unclear. We examined if there were differences in endothelial function, insulin stimulated endothelial function, 24 hour ambulatory blood pressure and heart rate during treatment with carvedilol, ...
The relationship between serum levels of metoprolol, hydroxymetoprolol and changes in psychomotor function as measured by standard reaction time and flash fusion frequency was studied. Blinded subjects were given placebo or 150 mg dose of metoprolol and crossed over on the next study day. Flash fusion frequency, reaction time, and serial blood levels of metoprolol and hydroxymetoprolol were col...
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...
BACKGROUND Pre-reperfusion administration of intravenous (IV) metoprolol reduces infarct size in ST-segment elevation myocardial infarction (STEMI). OBJECTIVES This study sought to determine how this cardioprotective effect is influenced by the timing of metoprolol therapy having either a long or short metoprolol bolus-to-reperfusion interval. METHODS We performed a post hoc analysis of the...
OBJECTIVE To investigate the effect of multiple-dose paroxetine intake on the stereoselective pharmacokinetics and the pharmacodynamics of metoprolol. METHODS We conducted an open trial with two sessions in eight healthy male volunteers. Racemic metoprolol (100 mg single oral dose) was administered before and after paroxetine treatment (20 mg/day for 6 days). The (R)- and (S)-metoprolol pharm...
The β1-adrenergic-receptor (ADRB1) antagonist metoprolol reduces infarct size in acute myocardial infarction (AMI) patients. The prevailing view has been that metoprolol acts mainly on cardiomyocytes. Here, we demonstrate that metoprolol reduces reperfusion injury by targeting the haematopoietic compartment. Metoprolol inhibits neutrophil migration in an ADRB1-dependent manner. Metoprolol acts ...
Metoprolol, a commonly prescribed β-blocker, is primarily metabolized by cytochrome P450 2D6 (CYP2D6), an enzyme with substantial genetic heterogeneity. Several smaller studies have shown that metoprolol pharmacokinetics is influenced by CYP2D6 genotype and metabolizer phenotype. To increase robustness of metoprolol pharmacokinetic estimates, a systematic review and meta-analysis of pharmacokin...
Background: Metoprolol (MTP) with its low biodegradability is one of the most dominant micropollutant in the effluent of wastewater treatment plants. The aim of this study was to investigate the removal of metoprolol from aqueous solutions by the activated carbon prepared from pine cones. Methods: The pine cones were activated using thermal activation method. Characteristics of the adsorbent w...
