MONITOR: Since acetylcholinesterase inhibitors can cause bradycardia and heart block due to vagotonic effects on the sinoatrial and atrioventricular nodes, additive effects may occur with other agents that also possess bradycardic effects such as beta-blockers, calcium channel blockers, digitalis, some protease inhibitors (atazanavir, lopinavir-ritonavir, saquinavir), amiodarone, dronedarone, moricizine, lacosamide, and mefloquine. A group of French investigators conducted a retrospective analysis of spontaneous reports in the French Pharmacovigilance Database concerning adverse drug reactions (ADRs) associated with use of the acetylcholinesterase inhibitors donepezil, galantamine, and rivastigmine. Two hundred and five cases of potential drug-drug interaction with bradycardic drugs (beta-blockers, calcium channel blockers, amiodarone, digoxin) were identified, 73 of which were associated with serious ADRs including five deaths due to syncope, bradycardia, arrhythmia, or cardiac arrest. However, no details on the individual cases such as patient characteristics or concomitant risk factors were provided, making the contribution of a potential drug interaction difficult to evaluate. The remainder of the cases were of no apparent clinical consequences. In contrast, a phase III trial of donepezil consisting of 1035 patients reported no significant increase in risk ratios for bradycardia during concomitant use of beta-blockers, nondihydropyridine calcium channel blockers, or digoxin.

MANAGEMENT: Caution is advised if acetylcholinesterase inhibitors are used concomitantly with bradycardic drugs. Patients with underlying structural heart disease, preexisting conduction system abnormalities, ischemic heart disease, or cardiomyopathies may be at increased risk for developing cardiac conduction disturbances and atrioventricular block. Patients should be advised to notify their physician if they experience dizziness, lightheadedness, fainting, or irregular heartbeat.

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
