hydroCHLOROthiazide eslicarbazepine

Applies to: Tribenzor (amlodipine / hydrochlorothiazide / olmesartan) and eslicarbazepine

MONITOR: Coadministration with other medications that can lower serum sodium levels such as diuretics, selective serotonin reuptake inhibitors (SSRIs), and serotonin-noradrenaline reuptake inhibitors (SNRIs) may potentiate the risk of hyponatremia associated with eslicarbazepine. In controlled clinical trials, 1% and 1.5% of patients treated with eslicarbazepine acetate 800 mg/day and 1200 mg/day, respectively, had at least one serum sodium value less than 125 mEq/L, compared to none of the patients receiving placebo. Additionally, 5.1% of eslicarbazepine-treated patients experienced decreases greater than 10 mEq/L, versus 0.7% of placebo-treated patients. These effects were dose-related and generally appeared within the first 8 weeks of treatment, with onset as early as after 3 days. Serious, life-threatening complications have included seizures, dehydration from severe nausea and vomiting, severe gait instability, and injury. Hospitalization and discontinuation of eslicarbazepine therapy were required in some cases. Concurrent hypochloremia was also present in patients with hyponatremia.

MANAGEMENT: Routine monitoring of serum sodium and chloride levels should be considered during maintenance treatment with eslicarbazepine acetate and concomitant use of other medications known to decrease serum sodium levels. Patients should be advised to seek medical attention if they experience potential signs and symptoms of hyponatremia such as nausea, vomiting, headache, malaise, lethargy, irritability, difficulty concentrating, memory impairment, confusion, weakness, muscle spasm, and unsteadiness (which may lead to falls). More severe and/or acute cases may include hallucination, syncope, seizure, coma, respiratory arrest, and death. Depending on the severity of hyponatremia, dosage reduction or discontinuation of eslicarbazepine acetate and other medications may be required, and appropriate medical intervention instituted as necessary.

hydroCHLOROthiazide amLODIPine

Applies to: Tribenzor (amlodipine / hydrochlorothiazide / olmesartan) and Tribenzor (amlodipine / hydrochlorothiazide / olmesartan)

The antihypertensive effect of amlodipine and thiazide diuretics may be additive. Management consists of monitoring blood pressure during coadministration, especially during the first 1 to 3 weeks of therapy.

Drug and food interactions

Moderate

olmesartan food

Applies to: Tribenzor (amlodipine / hydrochlorothiazide / olmesartan)

GENERALLY AVOID: Moderate-to-high dietary intake of potassium, especially salt substitutes, may increase the risk of hyperkalemia in some patients who are using angiotensin II receptor blockers (ARBs). ARBs can promote hyperkalemia through inhibition of angiotensin II-induced aldosterone secretion. Patients with diabetes, heart failure, dehydration, or renal insufficiency have a greater risk of developing hyperkalemia.

MANAGEMENT: Patients should receive dietary counseling and be advised to not use potassium-containing salt substitutes or over-the-counter potassium supplements without consulting their physician. If salt substitutes are used concurrently, regular monitoring of serum potassium levels is recommended. Patients should also be advised to seek medical attention if they experience symptoms of hyperkalemia such as weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs.

hydroCHLOROthiazide food

Applies to: Tribenzor (amlodipine / hydrochlorothiazide / olmesartan)

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. Patients should also avoid driving or operating hazardous machinery until they know how the medications affect them.

MONITOR: Calcium-containing products may decrease the effectiveness of calcium channel blockers by saturating calcium channels with calcium. Calcium chloride has been used to manage acute severe verapamil toxicity.

MANAGEMENT: Management consists of monitoring the effectiveness of calcium channel blocker therapy during coadministration with calcium products.

amLODIPine food

Applies to: Tribenzor (amlodipine / hydrochlorothiazide / olmesartan)

The consumption of grapefruit juice may slightly increase plasma concentrations of amlodipine. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Data have been conflicting and the clinical significance is unknown. Monitoring for calcium channel blocker adverse effects (e.g., headache, hypotension, syncope, tachycardia, edema) is recommended.

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.
