Interactions between your drugs

Moderate

clomiPRAMINE brimonidine ophthalmic

Applies to: Anafranil (clomipramine) and Qoliana (brimonidine ophthalmic)

MONITOR: Tricyclic and tetracyclic antidepressants can diminish the effects of centrally acting alpha agonists. The clinical significance, if any, of this interaction with respect to topically administered alpha-2 adrenergic receptor agonists such as brimonidine is unknown. The possibility of an additive or potentiating central nervous system (CNS)-depressant effect should be considered. Additive hypotensive effects and orthostasis may also occur, particularly during initial dosing of these agents.

MANAGEMENT: Patients receiving topical alpha-2 adrenergic receptor agonists in combination with tricyclic and tetracyclic antidepressants should be made aware of the potential for increased adverse effects such as drowsiness, dizziness, lightheadedness, confusion, hypotension and syncope, 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. No data are available on the level of circulating catecholamines after withdrawal of a topical alpha-2 adrenergic receptor agonist. Since tricyclic antidepressants can affect the metabolism and uptake of circulating amines, caution is advised.

Drug and food interactions

Moderate

clomiPRAMINE food

Applies to: Anafranil (clomipramine)

MONITOR: Limited data suggest that the administration of clomipramine with grapefruit juice or cranberry juice may significantly increase plasma drug concentrations of clomipramine. Clomipramine is initially demethylated by CYP450 1A2, 3A3 and 3A4 before undergoing further metabolism to 8-hydroxyclomipramine. The increase in clomipramine bioavailability may stem from inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The precise mechanism by which cranberry juice exerts its effects is unknown, but may involve inhibition of CYP450 isoenzymes. This interaction has occasionally been exploited in attempts to improve symptomatic control of obsessive compulsive disorder.

MANAGEMENT: Patients receiving clomipramine therapy who ingest cranberry juice, grapefruits, or grapefruit juice should be monitored for adverse effects and undue fluctuations in plasma drug levels.

clomiPRAMINE food

Applies to: Anafranil (clomipramine)

GENERALLY AVOID: The combination of ethanol and a tricyclic antidepressant may result in additive impairment of motor skills, especially driving skills. Also, one study has suggested that clomipramine metabolism is significantly impaired for several weeks or more following discontinuation of chronic alcohol consumption.

MANAGEMENT: Patients should be warned of this interaction and advised to limit their ethanol intake while taking tricyclic antidepressants. Monitoring for TCA toxicity (CNS depression, excessive anticholinergic effects, hypotension, arrhythmias) is recommended during alcohol withdrawal.

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.
