Concerns related to adverse effects:
• Angioedema: Angiotensin II receptor antagonists (ARBs) do not appear to elevate the risk of angioedema (Rasmussen 2019; Toh 2012). Patients with a history of angioedema due to an angiotensin-converting enzyme inhibitor must be educated that sometimes there can be recurrence within months following discontinuation (Beltrami 2011). No matter the cause of angioedema, prolonged frequent monitoring is required, especially if tongue, glottis, or larynx are involved, as they are associated with airway obstruction. Discontinue therapy immediately if angioedema occurs. Aggressive early management is critical. IM administration of epinephrine may be necessary. Do not readminister to patients who have had angioedema with ARBs.
• Angina/Myocardial infarction: Increased angina and/or myocardial infarction (MI) has occurred with initiation or dosage titration of dihydropyridine calcium channel blockers. Reflex tachycardia may occur resulting in angina and/or MI in patients with obstructive coronary disease, especially in the absence of concurrent beta-blockade.
• Gastrointestinal effects: Symptoms of sprue-like enteropathy (ie, severe, chronic diarrhea with significant weight loss) has been reported with olmesartan; may develop months to years after treatment initiation with villous atrophy commonly found on intestinal biopsy. Once other etiologies have been excluded, discontinue treatment and consider other antihypertensive treatment. Clinical and histologic improvement was noted after treatment was discontinued in a case series of 22 patients (Rubio-Tapia 2012).
• Hyperkalemia: May occur with olmesartan use; risk factors include kidney dysfunction, diabetes mellitus, concomitant use of potassium-sparing diuretics, potassium supplements, and/or potassium-containing salts. Use cautiously, if at all, with these agents and monitor potassium closely.
• Hypotension: Symptomatic hypotension may occur upon initiation in patients who are salt- or volume-depleted (eg, those treated with high-dose diuretics); also may occur in patients with severe aortic stenosis; correct volume depletion prior to administration. This transient hypotensive response is not a contraindication to further treatment with amlodipine/olmesartan.
• Kidney function deterioration: Olmesartan may be associated with deterioration of kidney 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 kidney 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 kidney function.
• Peripheral edema: The most common side effect of amlodipine is peripheral edema; occurs within 2 to 3 weeks of starting therapy.
Disease-related concerns:
• Aortic stenosis: Use with extreme caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia; symptomatic hypotension may occur in patients with severe aortic stenosis.
• Ascites: Generally, avoid use in patients with ascites due to cirrhosis or refractory ascites; if use cannot be avoided in patients with ascites due to cirrhosis, monitor BP and kidney function carefully to avoid rapid development of kidney failure (AASLD [Runyon 2013]).
• Hepatic impairment: Use with caution in patients with hepatic impairment; amlodipine and olmesartan exposure is increased. Initial therapy is not recommended; the appropriate combination dosage form is not available.
• Hypertrophic cardiomyopathy with left ventricular outflow tract obstruction: Use amlodipine with caution in patients with hypertrophic cardiomyopathy and left ventricular outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition (AHA/ACC [Ommen 2020]).
• Kidney impairment: Use with caution in patients with kidney impairment.
• Renal artery stenosis: Use olmesartan 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 kidney function unless possible benefits outweigh risks.
Special populations:
• Older adult: Initial therapy is not recommended in patients ≥75 years; the appropriate combination dosage form is not available.
• Pregnancy: [US Boxed Warning]: When pregnancy is detected, discontinue amlodipine/olmesartan as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.
• 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). Based on current research and clinical guidelines in patients undergoing noncardiac surgery, continuing ARBs is reasonable in the perioperative period. If ARBs are held before surgery, it is reasonable to restart postoperatively as soon as clinically feasible (ACC/AHA [Fleisher 2014]).
