Interactions between your drugs

Moderate

isoetharine opicapone

Applies to: isoetharine and opicapone

MONITOR: COMT inhibitors affect the elimination of drugs metabolized by catechol-O-methyltransferase (COMT) and may potentiate their effects. Arrhythmias, increased heart rate, and blood pressure changes may occur. Entacapone has increased heart rates up to 80% when coadministered with isoproterenol and epinephrine. Ventricular tachycardia has also been reported.

MANAGEMENT: The manufacturer recommends that caution be exercised when these drugs are given together. Monitoring for changes in hemodynamic status and ECG is recommended.

Drug and food interactions

Moderate

opicapone food

Applies to: opicapone

ADJUST DOSING INTERVAL: Food may reduce the rate and extent of absorption of opicapone. When opicapone was administered following a moderate fat/moderate calorie meal, mean opicapone peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 62% and 31%, respectively, while the time to reach peak concentration (Tmax) was delayed by 4 hours.

MANAGEMENT: Patients should avoid eating 1 to 2 hours before and after taking opicapone.

isoetharine food

Applies to: isoetharine

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.

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.
