Fixed combinations of two or three drugs are being frequently used in cardiovascular diseases. This approach markedly increases adherence of the patients to prolonged therapy and thus leads to better control of the diseases. Fixed combinations are often used in hypertension and coronary artery disease (CAD). Cosyrel is the first fixed combination of betablocker (bisoprolol fumarat) and ACE inhibitor (perindopril arginin) available in czech market. The advantage is availability in several concentrations (10 mg/10 mg, 10 mg/5 mg a 5 mg/10 mg a 5 mg/5 mg) , when first indicates bisoprolol dose and the second perindopril...

2014 American Association for Thoracic Surgery (AATS) guidelines recommend beta blocker for prevention and management of perioperative atrial fibrillation and flutter for thoracic surgical procedures. In recent years, transdermal patch of bisoprolol (TDPB) has become available in Japan. We examined the efficacy of TDPB for paroxysmal atrial fibrillation (PAF) after open heart surgery. Among 289 patients who had undergone open heart surgery in our hospital from December 2013 to April 2016, 48(16.6%)patients, for whom TDPB was used for PAF, were analyzed retrospectively...

BACKGROUND AND PURPOSE: Whole body physiologically based pharmacokinetic (PBPK) models have been increasingly applied in drug development to describe kinetic events of therapeutic agents in animals and human. The advantage of such modelling is the ability to incorporate vast amounts of physiological information, such as organ blood flow and volume, to ensure that the model is as close to reality as possible. EXPERIMENTAL APPROACH: Prior PBPK model development of enantiomers of a series of seven racemic betablockers, namely acebutolol, betaxolol, bisoprolol, metoprolol, oxprenolol, pindolol and propranolol, together with S-timolol in rat was based on tissue and blood concentration data at steady state...

Although recent retrospective studies suggested that the use of β-blockers appears to help improve the mortality rate and decrease the rate of exacerbation in chronic obstructive pulmonary disease (COPD) patients with heart failure, the effects of β-blockers on COPD patients without heart failure have not been established. Based on previous reports, we have launched a multicenter, prospective, single-arm phase II study to evaluate the preventive effect of the cardioselective β-blocker bisoprolol in COPD exacerbation, in Japanese individuals with moderate-to-severe COPD who do not have heart failure but do have hypertension requiring the use of medication...

We investigated if serial domiciliary measures of spirometry were sensitive at detecting subtle effects of beta-2 blockade associated with bisoprolol in (n = 17) patients with COPD. After a two-week run in on inhaled corticosteroid (ICS) and long acting beta-2 agonist (LABA): beclometasone/formoterol 100/6 µg, patients' started additional a long acting muscarinic receptor antagonist: (LAMA) Tiotropium 18 µg, with concomitant weekly dose titration of bisoprolol: 1.25-2.5-5 mg. After a further week of bisoprolol 5 mg, they were stepped back down to (ICS/LABA) for one week...

Acute dynamic exercise mobilizes CD34+ hematopoietic stem cells (HSCs) to the bloodstream, potentially serving as an economical adjuvant to boost the collection of HSCs from stem cell transplant donors. The mechanisms responsible for HSC mobilization with exercise are unknown but are likely due to hemodynamic perturbations, endogenous granulocyte-colony stimulating factor (G-CSF), and/or β2-adrenergic receptor (β2-AR) signaling. We characterized the temporal response of HSC mobilization and plasma G-CSF following exercise, and determined the impact of in vivo β-AR blockade on the exercise-induced mobilization of HSCs...

OBJECTIVE: Diabetes increases mortality in patients with chronic heart failure (CHF) and reduced left ventricular ejection fraction. Studies have questioned the safety of β-adrenoceptor blockers (β-blockers) in some patients with diabetes and reduced left ventricular ejection fraction. We examined whether β-blockers and ACE inhibitors (ACEI) are associated with differential effects on mortality in CHF patients with and without diabetes. RESEARCH DESIGN AND METHODS: We conducted a prospective cohort study of 1,797 patients with CHF recruited between 2006 and 2014, with mean follow-up of 4 years...

Direct enantiomeric resolution of commonly used five racemic β-adrenolytics, namely, bisoprolol, atenolol, propranolol, salbutamol and carvedilol has been achieved by thin layer chromatography using bovine serum albumin (BSA) as chiral additive in stationary phase. Successful resolution of the enantiomers of all racemic β-adrenolytics was achieved by use of different composition of simple organic solvents having no buffer or inorganic ions. The effect of variation in pH, temperature, amount of BSA as the additive, and composition of mobile phase on resolution was systematically studied...

BACKGROUND: Bisoprolol and metoprolol are moderately lipophilic, beta(1)-selective betablockers reported to cause adverse effects in the central nervous system (CNS), such as sleep disturbance, suggesting that both drugs may reach relevant concentrations in the brain. CNS beta(2)-receptor blockade has been suspected to be related to such effects. The higher molecular size of bisoprolol (325 Dalton) and the higher beta(1)-selectivity compared to metoprolol (267 Dalton) would suggest a lower rate of CNS effects...

Bisoprolol (B) exerts potential cardioprotective effects against myocardial ischemia/reperfusion (I/R) injury. Unfolded protein response (UPR) attenuates I/R injury induced apoptosis by reducing oxidative damage and inflammation response. The current study investigated whether the protective effects of bisoprolol resulted from modulating UPR and anti-inflammatory during myocardial I/R condition and elucidated its potential mechanisms. Sprague-Dawley rats were treated with B in the absence or presence of the injected UPR activator dithiothreitol (DTT) and then subjected to myocardial I/R surgery...

OBJECTIVE: β-Blockers are safe and improve survival in patients with both congestive heart failure (CHF) and COPD. However, the superiority of different types of β-blockers is still unclear among patients with CHF and COPD. The association between β-blockers and CHF exacerbation as well as COPD exacerbation remains unclear. The objective of this study was to compare the outcome of different β-blockers in patients with concurrent CHF and COPD. PATIENTS AND METHODS: We used the National Health Insurance Research Database in Taiwan to conduct a retrospective cohort study...

CLINICAL INTRODUCTION: A 72-year-old woman presented with an 8-year history of palpitations occurring every few weeks. They were sudden in onset, were associated with dizziness and could last for up to 2 hours. She was prescribed bisoprolol which reduced the frequency of events but did not abolish them. Baseline ECG and echocardiography were normal. She was referred for electrophysiological study. Despite initial difficulties, diagnostic catheters were placed in the right ventricular (RV) apex and in the coronary sinus (CS) via the right internal jugular vein and superior vena cava (SVC) (figure 1A)...

BACKGROUND: In register-based pharmacoepidemiological studies, construction of drug exposure periods from drug purchases is a major methodological challenge. Various methods have been applied but their validity is rarely evaluated. Our objective was to conduct an expert-opinion based evaluation of the correctness of drug use periods produced by different methods. METHODS: Drug use periods were calculated with three fixed methods: time windows, assumption of one Defined Daily Dose (DDD) per day and one tablet per day, and with PRE2DUP that is based on modelling of individual drug purchasing behavior...

Thyroid storm is a life-threatening disorder that remains a therapeutic challenge. Although β-blockers are the mainstay for treatment, their use can be challenging in cases complicated by rapid atrial fibrillation and decompensated heart failure. We present a case of thyroid storm-associated atrial fibrillation and decompensated heart failure complicated by gastrointestinal dysfunction secondary to diffuse peritonitis that was successfully managed by a switching therapy, in which the continuous intravenous administration of landiolol was changed to bisoprolol via transdermal patch, in the acute phase treatment...

WHAT IS KNOWN AND OBJECTIVE: Thrombocytopenia, not associated with bone marrow primary disease, is a common clinical problem. The possibility of drug-induced thrombocytopenia must be considered, especially in hospitalized patients. Drugs can cause thrombocytopenia by several mechanisms including direct bone marrow or other organ toxicity, and immune reactions. CASE DESCRIPTION: We describe a patient presenting with thrombocytopenia likely related to bisoprolol. WHAT IS NEW AND CONCLUSION: We report a case of bisoprolol-induced thrombocytopenia which resolved with drug discontinuation and steroid therapy...
