Drug Interactions between apraclonidine ophthalmic and Duo-Medihaler
This report displays the potential drug interactions for the following 2 drugs:
- apraclonidine ophthalmic
- Duo-Medihaler (isoproterenol/phenylephrine)
Interactions between your drugs
isoproterenol phenylephrine
Applies to: Duo-Medihaler (isoproterenol / phenylephrine) and Duo-Medihaler (isoproterenol / phenylephrine)
MONITOR: Coadministration of beta-2 adrenergic agonists with other adrenergic agents may potentiate the risk of cardiovascular side effects. Beta-2 adrenergic agonists can produce clinically significant cardiovascular effects including increases in pulse rate and systolic or diastolic blood pressure as well as ECG changes such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression. The risk is lower when beta-2 adrenergic agonists are inhaled at normally recommended dosages. However, these effects may be more common when the drugs are administered systemically or when recommended dosages are exceeded.
MANAGEMENT: Caution is advised if beta-2 adrenergic agonists are used concomitantly with other adrenergic agents, particularly in patients with cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, hypertrophic obstructive cardiomyopathy, or hypertension. Blood pressure and heart rate should be closely monitored.

isoproterenol apraclonidine ophthalmic
Applies to: Duo-Medihaler (isoproterenol / phenylephrine) and apraclonidine ophthalmic
Coadministration with sympathomimetic agents may diminish the effects of topically applied alpha-2 adrenergic receptor agonists such as apraclonidine ophthalmic. The precise mechanism for this interaction has not been delineated. Clinical data are lacking; however, caution is suggested if concomitant use is required.

Drug and food interactions
apraclonidine ophthalmic food
Applies to: apraclonidine ophthalmic
MONITOR: Topically administered alpha-2 adrenergic receptor agonists such as apraclonidine and brimonidine are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. Although the interaction has not been specifically studied, the possibility of an additive or potentiating effect with central nervous system (CNS) depressants such as alcohol, barbiturates, opiates, anxiolytics, sedatives, and anesthetics should be considered. Additive hypotensive effects and orthostasis may also occur with some CNS depressants and other agents that have these effects, particularly during initial dosing and/or parenteral administration.
MANAGEMENT: Patients receiving topical alpha-2 adrenergic receptor agonists in combination with agents that can cause CNS depression should be made aware of the potential for increased adverse effects such as drowsiness, dizziness, lightheadedness and confusion, and counseled to avoid activities requiring mental alertness until they know how these agents affect them. Patients should also avoid rising abruptly from a sitting or recumbent position and notify their physician if they experience orthostasis or tachycardia.

isoproterenol food
Applies to: Duo-Medihaler (isoproterenol / phenylephrine)
MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.
MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.
