Medication Safety Issues

​Geriatric Patients: High-Risk Medication:

​Other safety concerns:

Contraindications

Hypersensitivity to eprosartan, hydrochlorothiazide, sulfonamide-derived drugs, or any component of the formulation; concomitant use with aliskiren in patients with diabetes mellitus and/or moderate to severe renal impairment (GFR <60 mL/minute/1.73 m2); anuria; severe renal or hepatic impairment; cholestasis and biliary obstructive disorders; hemodynamically significant bilateral renovascular disease or severe stenosis of a solitary functioning kidney; refractory hyponatremia, hypokalemia, or hypercalcemia; symptomatic hyperuricemia/gout; hereditary problems of galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption; concomitant use with angiotensin-converting enzyme inhibitors in patients with diabetic nephropathy; pregnancy; breastfeeding.

Note: Although the product labeling states this medication is contraindicated with other sulfonamide-containing drug classes, the scientific basis of this statement has been challenged. See “Warnings/Precautions” for more detail.

Warnings/Precautions

Concerns related to adverse effects:

• Angioedema: Angioedema has been reported rarely with some angiotensin II receptor antagonists (ARBs) and may occur at any time during treatment (especially following first dose). It may involve the head and neck (potentially compromising airway) or the intestine (presenting with abdominal pain). Patients with idiopathic or hereditary angioedema or previous angioedema associated with ACE-inhibitor therapy may be at an increased risk. Prolonged frequent monitoring may be required, especially if tongue, glottis, or larynx are involved, as they are associated with airway obstruction. Patients with a history of airway surgery may have a higher risk of airway obstruction. Discontinue therapy immediately if angioedema occurs. Aggressive early management is critical. Intramuscular (IM) administration of epinephrine may be necessary. Do not readminister to patients who have had angioedema with ARBs.

• Electrolyte disturbances: Hyperkalemia may occur with angiotensin II receptor antagonists; risk factors include renal dysfunction, diabetes mellitus, and concomitant use of ACE inhibitors, aliskiren, potassium-sparing diuretics, potassium supplements, and/or potassium-containing salts. Use cautiously, if at all, with these agents and monitor potassium closely. Thiazide diuretics may cause hypokalemia, hypochloremic alkalosis, hypomagnesemia, and hyponatremia.

• Gout: In certain patients with a history of gout, a familial predisposition to gout, or chronic renal failure, gout can be precipitated by hydrochlorothiazide. This risk may be increased with doses ≥25 mg (Gurwitz 1997).

• Hypersensitivity reactions: Hypersensitivity reactions may occur with hydrochlorothiazide. Risk is increased in patients with a history of allergy or bronchial asthma.

• Hypotension: Symptomatic hypotension may occur upon initiation in patients who are salt- or volume-depleted (eg, those treated with high-dose diuretics); correct volume depletion prior to administration. This transient hypotensive response is not a contraindication to further treatment with eprosartan.

• Ocular effects: Hydrochlorothiazide may cause acute transient myopia and acute angle-closure glaucoma, typically occurring within hours to weeks following initiation; discontinue therapy immediately in patients with acute decreases in visual acuity or ocular pain. Additional treatments may be needed if uncontrolled intraocular pressure persists. Risk factors may include a history of sulfonamide or penicillin allergy.

• Photosensitivity: Photosensitization may occur.

• Renal function deterioration: May be associated with deterioration of renal function and/or increases in serum creatinine, particularly in patients with low renal blood flow (eg, renal artery stenosis, heart failure) whose glomerular filtration rate (GFR) is dependent on efferent arteriolar vasoconstriction by angiotensin II; deterioration may result in oliguria, acute renal failure, and progressive azotemia. Small increases in serum creatinine may occur following initiation; consider discontinuation only in patients with progressive and/or significant deterioration in renal function.

• Skin cancer, nonmelanoma: Prolonged use (≥3 years) may increase the risk for squamous cell carcinoma up to 4 times and increase the risk for basal cell carcinoma up to 1.25 times compared to patients not treated with hydrochlorothiazide (Pedersen 2018; Pottegård 2017).

• Sulfonamide (“sulfa”) allergy: The FDA-approved product labeling for many medications containing a sulfonamide chemical group includes a broad contraindication in patients with a prior allergic reaction to sulfonamides. There is a potential for cross-reactivity between members of a specific class (eg, two antibiotic sulfonamides). However, concerns for cross-reactivity have previously extended to all compounds containing the sulfonamide structure (SO2NH2). An expanded understanding of allergic mechanisms indicates cross-reactivity between antibiotic sulfonamides and nonantibiotic sulfonamides may not occur or at the very least this potential is extremely low (Brackett 2004; Johnson 2005; Slatore 2004; Tornero 2004). In particular, mechanisms of cross-reaction due to antibody production (anaphylaxis) are unlikely to occur with nonantibiotic sulfonamides. T-cell-mediated (type IV) reactions (eg, maculopapular rash) are less well understood and it is not possible to completely exclude this potential based on current insights. In cases where prior reactions were severe (Stevens-Johnson syndrome/TEN), some clinicians choose to avoid exposure to these classes.

Disease-related concerns:

• Aortic/mitral stenosis: Use with caution in patients with significant aortic/mitral stenosis.

• Bariatric surgery: Dehydration: Avoid diuretics in the immediate postoperative period after bariatric surgery; electrolyte disturbances and dehydration may occur. Diuretics may be resumed, if indicated, once oral fluid intake goals are met (Ziegler 2009).

• Diabetes: Use hydrochlorothiazide with caution in patients with prediabetes or diabetes mellitus; may see a change in glucose control.

• Hepatic impairment: Use caution in patients with hepatic impairment; in progressive or severe liver disease, avoid electrolyte and acid/base imbalances that might lead to hepatic encephalopathy/coma.

• Hypercalcemia: Thiazide diuretics may decrease renal calcium excretion; consider avoiding use in patients with hypercalcemia.

• Hypercholesterolemia: Use with caution in patients with moderate or high cholesterol concentrations; increased cholesterol and triglyceride levels have been reported with thiazides.

• Parathyroid disease: Thiazide diuretics reduce calcium excretion; pathologic changes in the parathyroid glands with hypercalcemia and hypophosphatemia have been observed with prolonged use; should be discontinued prior to testing for parathyroid function.

• Renal artery stenosis: Use eprosartan with caution in patients with unstented unilateral/bilateral renal artery stenosis. When unstented bilateral renal artery stenosis is present, use is generally avoided due to the elevated risk of deterioration in renal function unless possible benefits outweigh risks.

• Renal impairment: Use eprosartan with caution with preexisting renal insufficiency and severe renal impairment. Cumulative effects of hydrochlorothiazide, including azotemia, may develop in patients with impaired renal function. Avoid hydrochlorothiazide in severe renal disease (ineffective); may precipitate azotemia; discontinue or consider withholding if renal impairment occurs.

• Systemic lupus erythematosus (SLE): Hydrochlorothiazide can cause SLE exacerbation or activation.

Special populations:

• Pregnancy: Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.

• Surgical patients: In patients on chronic angiotensin receptor blocker (ARB) therapy, intraoperative hypotension may occur with induction and maintenance of general anesthesia; however, discontinuation of therapy prior to surgery is controversial. If continued preoperatively, avoidance of hypotensive agents during surgery is prudent (Hillis 2011).

Geriatric Considerations

See individual agents. Combination products are not recommended as first-line treatment. Use only if doses of individual agents correspond to the combination available. Hydrochlorothiazide is not effective in patients with a CrCl <30 mL/minute; therefore, it may not be a useful agent in many elderly patients.

Pregnancy Considerations

Use is contraindicated in pregnant women. Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.

Refer to individual monographs for additional information.

Breast-Feeding Considerations

Excretion of eprosartan in breast milk is not known; hydrochlorothiazide is excreted in breast milk.

Use of this combination is contraindicated in breastfeeding women. Refer to individual monographs for additional information.

Monitoring Parameters

BP; serum electrolytes, BUN, creatinine, and eGFR (before and after dose changes and at least annually thereafter).

Hypertension: The 2017 guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults (ACC/AHA [Whelton 2017]):

Confirmed hypertension and known CVD or 10-year ASCVD risk ≥10%: Target BP <130/80 mm Hg is recommended.

Confirmed hypertension without markers of increased ASCVD risk: Target BP <130/80 mm Hg may be reasonable.

Diabetes and hypertension: The American Diabetes Association (ADA) guidelines (ADA 2020): Goal BP <140/90 mm Hg

Known ASCVD or 10-year ASCVD risk >15%: Goal BP <130/80 mm Hg if this can be safely attained.

10-year ASCVD risk <15%, lower risk of CVD: Goal BP <140/90 mm Hg.

Advanced Practitioners Physical Assessment/Monitoring

Use caution in presence of renal impairment. Assess potential for interactions with other pharmacological agents or herbal products that may impact blood pressure. Assess allergy history prior to beginning therapy. Assess electrolytes, BUN, and creatinine regularly during therapy. Monitor for hypotension, hypokalemia, hyponatremia, hypercalcemia, and confusion regularly. Caution patients with diabetes to monitor glucose levels closely; may alter glucose control.

Nursing Physical Assessment/Monitoring

Allergy history should be identified prior to beginning therapy. Monitor for hypotension, hyponatremia, hypokalemia, and hypercalcemia.

Mechanism of Action

Hydrochlorothiazide inhibits sodium reabsorption in the distal tubules causing increased excretion of sodium and water as well as potassium and hydrogen ions. Eprosartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland.
