Overdosage/Toxicology:

Drug Interactions:

Alpha-blockers (prazosin, terazosin): Concurrent use of beta-blockers may increase risk of orthostasis.

AV conduction-slowing agents (digoxin): Effects may be additive with beta-blockers.

Clonidine: Hypertensive crisis after or during withdrawal of either agent.

CYP3A4 inducers: CYP3A4 inducers may decrease the levels/effects of bisoprolol. Example inducers include aminoglutethimide, carbamazepine, nafcillin, nevirapine, phenobarbital, phenytoin, and rifamycins.

CYP3A4 inhibitors: May increase the levels/effects of bisoprolol. Example inhibitors include azole antifungals, ciprofloxacin, clarithromycin, diclofenac, doxycycline, erythromycin, imatinib, isoniazid, nefazodone, nicardipine, propofol, protease inhibitors, quinidine, and verapamil.

Glucagon: Bisoprolol may blunt the hyperglycemic action of glucagon.

Insulin: Bisoprolol may mask tachycardia from hypoglycemia.

NSAIDs (ibuprofen, indomethacin, naproxen, piroxicam) may reduce the antihypertensive effects of beta-blockers.

Salicylates may reduce the antihypertensive effects of beta-blockers.

Sulfonylureas: Beta-blockers may alter response to hypoglycemic agents.

Patient Education:

Anesthesia and Critical Care Concerns/Other Considerations:

Surgery: Atenolol has also been shown to improve cardiovascular outcomes when used in the perioperative period in patients with underlying cardiovascular disease who are undergoing noncardiac surgery. Bisoprolol in high-risk patients undergoing vascular surgery reduced the perioperative incidence of death from cardiac causes and nonfatal myocardial infarction.

Withdrawal: Beta-blocker therapy should not be withdrawn abruptly, but gradually tapered to avoid acute tachycardia and hypertension.

Cardiovascular Considerations:

Hypertension: Beta-blocker therapy in the treatment of hypertension has been associated with improved cardiovascular outcomes. This class of drug is beneficial for elderly patients with hypertension. A recent UKPDS study showed that beta-blocker therapy (atenolol) was as effective as an ACE inhibitor in reducing cardiovascular events and that the benefits of therapy were related more to the degree of antihypertensive efficacy rather than the class of drug used.

Myocardial infarction: Beta-blockers, in general without intrinsic sympathomimetic activity (ISA), have been shown to decrease morbidity and mortality when initiated in the acute treatment of myocardial infarction and continued long-term. In this setting, therapy should be avoided in patients with hypotension, cardiogenic shock, or heart block.

Surgery: Atenolol has also been shown to improve cardiovascular outcomes when used in the perioperative period in patients with underlying cardiovascular disease who are undergoing noncardiac surgery. Bisoprolol in high-risk patients undergoing vascular surgery reduced the perioperative incidence of death from cardiac causes and nonfatal myocardial infarction.

Atrial fibrillation: Beta-blocker therapy provides effective rate control in patients with atrial fibrillation.

Angina: Beta-blockers are effective in the treatment of angina as monotherapy or when combined with nitrates and/or calcium channel blockers. In patients with severe intractable angina requiring negative cardiac chronotropic medications, pacemaker placement has been carried out to maintain heart rate in the setting of large doses of beta-blockers and/or calcium channel blockers. Beta-blockers are ineffective in the treatment of pure vasospastic (Prinzmetal) angina.

Unstable angina/non-ST-segment elevation MI: In the treatment of unstable angina/non-ST-segment elevation MI, a beta-blocker, with the first dose administered intravenously if there is ongoing chest pain, followed by oral administration, is recommended (in the absence of contraindications).

Withdrawal: Beta-blocker therapy should not be withdrawn abruptly, but gradually tapered to avoid acute tachycardia and hypertension.

Heart failure: There is emerging evidence that beta-blocker therapy, without intrinsic sympathomimetic activity (ISA), should be initiated in select patients with stable congestive heart failure (NYHA Class II-III). To date, carvedilol, sustained release metoprolol, and bisoprolol have demonstrated a beneficial effect on morbidity and mortality. It is important that beta-blocker therapy be instituted initially at very low doses with gradual and very careful titration. In the CIBIS-II trial, bisoprolol (beta-1 selective beta-blocker) improved morbidity and mortality in patients with moderate heart failure (NYHA Class III-IV).
