Monitor

The chronic use or abuse of laxatives may potentiate the pharmacologic effects of diuretics. Laxatives can cause significant losses of fluid and electrolytes, including sodium, potassium, magnesium and zinc, and these effects may be additive to those of diuretics.

Management

In general, laxatives should only be used on a short-term, intermittent basis in recommended dosages. During concomitant use with diuretics, patients should be advised to contact their physician if they experience signs and symptoms of fluid and electrolyte depletion such as dizziness, lightheadedness, dry mouth, thirst, fatigue, weakness, lethargy, muscle cramps, decreased urination, postural hypotension, and tachycardia. If maintenance of bowel regularity is required, patients should be advised to exercise and increase fiber in the diet and/or consider the use of bulk-forming laxatives.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

eplerenone Food/Lifestyle

Applies to: eplerenone
Generally avoid

Coadministration with grapefruit juice may increase the plasma concentrations of eplerenone. The primary mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Inhibition of hepatic CYP450 3A4 may also contribute. In drug interaction studies, administration of a single 100 mg dose of eplerenone in combination with grapefruit juice resulted in a 25% increase in eplerenone systemic exposure (AUC). High blood levels of eplerenone can increase the risk of side effects including hyperkalemia. 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.

Management

It may be advisable for patients to avoid the consumption of grapefruit, grapefruit juice, or supplements that contain grapefruit during treatment with eplerenone.

Moderate:

senna multivitamins with minerals

Applies to: SenoSol (senna)
Generally avoid

Chronic use of stimulant laxatives may decrease the absorption of fat-soluble vitamins (A, D, E, and K) and minerals such as calcium, potentially leading to deficiencies. This effect is due to accelerated intestinal transit time, which reduces nutrient absorption.

Management

To minimize this risk, limit the use of stimulant laxatives to short-term or occasional use.

Disease interactions

8 potential interactions Applies to: 8 conditions, including Type 2 Diabetes, Inflammatory Bowel Disease, Hyperkalemia, Liver Disease, and Bleeding Disorder.

Appendicitis

Major:

SenoSol

The senna in SenoSol has a major potential interaction with Appendicitis.

The use of stimulant laxatives is contraindicated in patients with or who may have acute surgical abdomen or appendicitis. These patients may be candidates for emergency surgery. Stimulant laxatives should also not be administered to patients with abdominal pain, particularly if the cause has not been determined.

Bleeding Disorder

Major:

SenoSol

The senna in SenoSol has a major potential interaction with Bleeding Disorder.

The use of stimulant laxatives is contraindicated in patients with anal or rectal fissures. These preparations may cause irritation, burning sensation, and proctitis.

Gastrointestinal Obstruction

Major:

SenoSol

The senna in SenoSol has a major potential interaction with Gastrointestinal Obstruction.

The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.

Hyperkalemia

Major:

eplerenone

Eplerenone has a major potential interaction with Hyperkalemia.

The use of eplerenone is contraindicated in the presence of elevated serum potassium concentrations (> 5.5 mEq/L). Eplerenone is a blocker of aldosterone binding at the mineralocorticoid receptor and can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Careful monitoring of serum potassium levels is necessary in patients who are at risk for the development of hyperkalemia (including those receiving concomitant ACE inhibitors or angiotensin II receptor antagonists), especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. In clinical trials, monitoring occurred every 2 weeks for the first 1 to 2 months, then monthly thereafter. Eplerenone should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L.

Inflammatory Bowel Disease

Major:

SenoSol

The senna in SenoSol has a major potential interaction with Inflammatory Bowel Disease.

The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.

Liver Disease

Moderate:

eplerenone

Eplerenone has a moderate potential interaction with Liver Disease.

Eplerenone is primarily metabolized by the liver. In patients with moderate (Child-Pugh Class B) hepatic impairment given eplerenone 400 mg, the steady-state peak plasma concentration (Cmax) and systemic exposure (AUC) of eplerenone were increased by 3.6% and 42%, respectively, compared to those in normal subjects. In 16 patients with mild to moderate hepatic impairment who received 400 mg of eplerenone, no elevations in serum potassium above 5.5 mmol/L were observed. Their mean increase in serum potassium was 0.12 mEq/L compared to 0.13 mEq/L in normal controls. No adjustment of the starting dosage is recommended for patients with mild to moderate hepatic impairment. The use of eplerenone in patients with severe hepatic impairment has not been evaluated, thus caution is advised.

Renal Dysfunction

Major:

eplerenone

Eplerenone has a major potential interaction with Renal Dysfunction.

The use of eplerenone is contraindicated in patients with renal impairment as defined by serum creatinine above 2.0 mg/dL for males or 1.8 mg/dL for females, or a creatinine clearance (CrCl) below 50 mL/min. These patients are at increased risk of developing persistent hyperkalemia, which is the principal adverse effect of eplerenone and can lead to potentially life-threatening cardiac arrhythmias. The incidence of hyperkalemia increases with decreasing renal function. In clinical studies of eplerenone, serum potassium levels exceeding 5.5 mEq/L were observed in 10.4% of treated patients with baseline calculated CrCl less than 70 mL/min, 5.6% of patients with baseline CrCl 70 to 100 mL/min, and 2.6% of patients with baseline CrCl greater than 100 mL/min. Careful monitoring of serum potassium levels is necessary in patients treated with eplerenone who are at risk for the development of hyperkalemia, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. In clinical trials, monitoring occurred every 2 weeks for the first 1 to 2 months, then monthly thereafter. Eplerenone should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L.

Type 2 Diabetes

Major:

eplerenone

Eplerenone has a major potential interaction with Type 2 Diabetes.

The use of eplerenone is contraindicated in patients with type II diabetes mellitus and microalbuminuria. These patients are at increased risk of developing persistent hyperkalemia, which is the principal adverse effect of eplerenone and can lead to potentially life-threatening cardiac arrhythmias. In a study of such patients treated with a 200 mg/day dose, the frequency of maximum serum potassium levels exceeding 5.5 mEq/L was 33% with eplerenone alone and 38% in combination with enalapril. In other patient populations, the frequency has been reported at 1% for the 200 mg/day dose and 8.7% for the 400 mg/day dose. Careful monitoring of serum potassium levels is necessary in patients treated with eplerenone who are at risk for the development of hyperkalemia, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. In clinical trials, monitoring occurred every 2 weeks for the first 1 to 2 months, then monthly thereafter. Eplerenone should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L.
