Interactions between your drugs
clomiPRAMINE cariprazine
Applies to: clomipramine and cariprazine
MONITOR: Agents with anticholinergic properties (e.g., sedating antihistamines; antispasmodics; neuroleptics; phenothiazines; skeletal muscle relaxants; tricyclic antidepressants; disopyramide) may have additive effects when used in combination. Excessive parasympatholytic effects may result in paralytic ileus, hyperthermia, heat stroke, and the anticholinergic intoxication syndrome. Peripheral symptoms of intoxication commonly include mydriasis, blurred vision, flushed face, fever, dry skin and mucous membranes, tachycardia, urinary retention, and constipation. Central symptoms may include memory loss, disorientation, incoherence, hallucinations, psychosis, delirium, hyperactivity, twitching or jerking movements, stereotypy, and seizures. Central nervous system-depressant effects may also be additively or synergistically increased when these agents are combined, especially in elderly or debilitated patients. Use of neuroleptics in combination with other neuroleptics or anticholinergic agents may increase the risk of tardive dyskinesia. In addition, some neuroleptics and tricyclic antidepressants may cause prolongation of the QT interval and theoretically, concurrent use of two or more drugs that can cause QT interval prolongation may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death.
MANAGEMENT: Caution is advised when agents with anticholinergic properties are combined, particularly in the elderly and those with underlying organic brain disease, who tend to be more sensitive to the central anticholinergic effects of these drugs and in whom toxicity symptoms may be easily overlooked. Patients should be advised to notify their physician promptly if they experience potential symptoms of anticholinergic intoxication such as abdominal pain, fever, heat intolerance, blurred vision, confusion, and/or hallucinations. Ambulatory patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them. A reduction in anticholinergic dosages may be necessary if excessive adverse effects develop.

Drug and food interactions
clomiPRAMINE food
Applies to: 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.

cariprazine food
Applies to: cariprazine
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of cariprazine. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of cariprazine by certain compounds present in grapefruit. When cariprazine (0.5 mg/day) was coadministered with the potent CYP450 3A4 inhibitor, ketoconazole (400 mg/day), cariprazine peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 3.5- and 4-fold, respectively, while Cmax and AUC of DDCAR increased by approximately 1.5-fold each. The Cmax and AUC of another active metabolite, desmethyl cariprazine (DCAR), decreased by approximately one-third. The interaction has not been studied with grapefruit juice. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased exposure to cariprazine may increase the risk of adverse effects such as extrapyramidal symptoms, cognitive and motor impairment, hyperglycemia, dyslipidemia, weight gain, orthostatic hypotension, leucopenia, neutropenia, seizures, and dysphagia.
MANAGEMENT: Patients should avoid the consumption of grapefruit and grapefruit juice during treatment with cariprazine.

clomiPRAMINE food
Applies to: 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.
