Hypertension: Management of hypertension

Guideline recommendations: The 2017 Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults recommends if monotherapy is warranted, in the absence of comorbidities (eg, cerebrovascular disease, chronic kidney disease, diabetes, heart failure, ischemic heart disease, etc.), that thiazide-like diuretics or dihydropyridine calcium channel blockers may be preferred options due to improved cardiovascular endpoints (eg, prevention of heart failure and stroke). ACE inhibitors and ARBs are also acceptable for monotherapy. Combination therapy may be required to achieve blood pressure goals and is initially preferred in patients at high risk (stage 2 hypertension or atherosclerotic cardiovascular disease [ASCVD] risk ≥10%) (ACC/AHA [Whelton 2017]).

Use: Off Label

Non–ST-elevation acute coronary syndromeyes

Based on the American College of Cardiology/American Heart Association (ACC/AHA) guidelines for the management of patients with non-ST-elevation acute coronary syndromes (NSTE-ACS), an ACE inhibitor should be initiated and continued indefinitely after NSTE-ACS in patients with a left ventricular ejection fraction (LVEF) ≤40% and in those with hypertension, diabetes mellitus, or stable CKD unless contraindicated. Use of an ACE inhibitor may also be useful in all other patients with cardiac or other vascular disease.

Stable coronary artery diseaseyes

Based on the ACC/AHA guideline for the diagnosis and management of patients with stable ischemic heart disease, an ACE inhibitor or ARB should be prescribed in all patients with stable ischemic heart disease who also have hypertension, diabetes mellitus, LVEF <40%, or CKD unless contraindicated.

ST-elevation acute coronary syndromeyes

Based on the 2013 ACC/AHA guidelines for the management of patients with ST-elevation acute coronary syndromes (STE-ACS), an ACE inhibitor should be initiated within the first 24 hours to all patients with STE-ACS with anterior location, HF, or LVEF ≤40%, unless contraindicated. It is also reasonable to initiate an ACE inhibitor in all patients with STE-ACS.

Contraindications

Hypersensitivity to moexipril or any component of the formulation; angioedema related to previous treatment with an ACE inhibitor; concomitant use with aliskiren in patients with diabetes mellitus

Documentation of allergenic cross-reactivity for ACE inhibitors is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.

Warnings/Precautions

Concerns related to adverse effects:

• Angioedema: At any time during treatment (especially following first dose), angioedema may occur rarely with ACE inhibitors; it may involve the head and neck (potentially compromising airway) or the intestine (presenting with abdominal pain). African-Americans and patients with idiopathic or hereditary angioedema may be at an increased risk. Risk may also be increased with concomitant use of mTOR inhibitor (eg, everolimus) therapy. 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. Aggressive early and appropriate management is critical. Use in patients with previous angioedema associated with ACE inhibitor therapy is contraindicated.
• Cholestatic jaundice: A rare toxicity associated with ACE inhibitors includes cholestatic jaundice, which may progress to fulminant hepatic necrosis (some fatal); discontinue if marked elevation of hepatic transaminases or jaundice occurs.
• Cough: An ACE inhibitor cough is a dry, hacking, nonproductive one that usually occurs within the first few months of treatment and should generally resolve within 1 to 4 weeks after discontinuation of the ACE inhibitor. Other causes of cough should be considered (eg, pulmonary congestion in patients with heart failure) and excluded prior to discontinuation.
• Hyperkalemia: May occur with ACE inhibitors; risk factors include renal 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.
• Hypersensitivity reactions: Anaphylactic/anaphylactoid reactions can occur with ACE inhibitors. Severe anaphylactoid reactions may be seen during hemodialysis (eg, CVVHD) with high-flux dialysis membranes (eg, AN69), and rarely, during low density lipoprotein apheresis with dextran sulfate cellulose. Rare cases of anaphylactoid reactions have been reported in patients undergoing sensitization treatment with hymenoptera (bee, wasp) venom while receiving ACE inhibitors.
• Hypotension/syncope: Symptomatic hypotension with or without syncope can occur with ACE inhibitors (usually with the first several doses); effects are most often observed in volume-depleted patients; correct volume depletion prior to initiation; close monitoring of patient is required especially with initial dosing and dosing increases; blood pressure must be lowered at a rate appropriate for the patient's clinical condition. Although dose reduction may be necessary, hypotension is not a reason for discontinuation of future ACE inhibitor use especially in patients with heart failure where a reduction in systolic blood pressure is a desirable observation.
• Neutropenia/agranulocytosis: Another ACE inhibitor, captopril, has been associated with rare cases of agranulocytosis, neutropenia or leukopenia with myeloid hypoplasia. Patients with renal impairment are at high risk of developing neutropenia. Patients with both renal impairment and collagen vascular disease (eg, systemic lupus erythematosus) are at an even higher risk of developing neutropenia. Periodically monitor CBC with differential in these patients.
• Renal function deterioration: May be associated with deterioration of renal function and/or increases in BUN and serum creatinine, particularly in patients with low renal blood flow (eg, renal artery stenosis, heart failure) whose 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 (Bakris 2000).

Disease-related concerns:

• Aortic stenosis: Use with caution in patients with aortic stenosis; may reduce coronary perfusion resulting in ischemia.
• Ascites: 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 blood pressure and renal function carefully to avoid rapid development of renal failure (AASLD [Runyon 2012]).
• Cardiovascular disease: Initiation of therapy in patients with ischemic heart disease or cerebrovascular disease warrants close observation due to the potential consequences posed by falling blood pressure (eg, MI, stroke). Fluid replacement, if needed, may restore blood pressure; therapy may then be resumed. Discontinue therapy in patients whose hypotension recurs.
• Collagen vascular disease: Use with caution in patients with collagen vascular disease especially with concomitant renal impairment; may be at increased risk for hematologic toxicity.
• Hypertrophic cardiomyopathy (HCM) with outflow tract obstruction: Use with caution in patients with HCM and outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition (ACCF/AHA [Gersh, 2011]).
• Renal artery stenosis: Use 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 with caution in pre-existing renal insufficiency; dosage adjustment may be needed. Avoid rapid dosage escalation which may lead to further renal impairment.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Black patients: ACE inhibitors effectiveness is less in black patients than in non-blacks. In addition, ACE inhibitors cause a higher rate of angioedema in black than in non-black patients.
• Pregnancy: [US Boxed Warning]: 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 ACE inhibitor therapy, intraoperative hypotension may occur with induction and maintenance of general anesthesia; use with caution before, during, or immediately after major surgery. Cardiopulmonary bypass, intraoperative blood loss, or vasodilating anesthesia increases endogenous renin release. Use of ACE inhibitors perioperatively will blunt angiotensin II formation and may result in hypotension. 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 non-cardiac surgery, continuing ACE inhibitors is reasonable in the perioperative period. If ACE inhibitors are held before surgery, it is reasonable to restart postoperatively as soon as clinically feasible (ACC/AHA [Fleisher 2014]).

Monitoring Parameters

Blood pressure; BUN, serum creatinine and potassium; if patient has collagen vascular disease and/or renal impairment, periodically monitor CBC with differential

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 atherosclerotic cardiovascular disease (ASCVD) risk ≥10%: Target blood pressure <130/80 mm Hg is recommended

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

Diabetes and hypertension: The American Diabetes Association (ADA) guidelines (ADA 2019):

Patients 18 to 65 years of age, without ASCVD, and 10-year ASCVD risk <15%: Target blood pressure <140/90 mm Hg is recommended.

Patients 18 to 65 years of age and known ASCVD or 10-year ASCVD risk >15%: Target blood pressure <130/80 mm Hg may be appropriate if it can be safely attained.

Patients >65 years of age (healthy or complex/intermediate health): Target blood pressure <140/90 mm Hg is recommended.

Patients >65 years of age (very complex/poor health): Target blood pressure <150/90 mm Hg is recommended.

Pregnancy

Pregnancy Risk Factor

Pregnancy Considerations

Exposure to an angiotensin-converting enzyme (ACE) inhibitor during the first trimester of pregnancy may be associated with an increased risk of fetal malformations (ACOG 203 2019; ESC [Regitz-Zagrosek 2018]); however, outcomes observed may also be influenced by maternal disease (ACC/AHA [Whelton 2017]).

[US Boxed Warning]: 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. Drugs that act on the renin-angiotensin system are associated with oligohydramnios. Oligohydramnios, due to decreased fetal renal function, may lead to fetal lung hypoplasia and skeletal malformations. The use of these drugs in pregnancy is also associated with anuria, hypotension, renal failure, skull hypoplasia, and death in the fetus/neonate. Infants exposed to an ACE inhibitor in utero should be monitored for hyperkalemia, hypotension, and oliguria. Oligohydramnios may not appear until after irreversible fetal injury has occurred. Exchange transfusions or dialysis may be required to reverse hypotension or improve renal function, although data related to the effectiveness in neonates is limited.

Chronic maternal hypertension is also associated with adverse events in the fetus/infant. Chronic maternal hypertension may increase the risk of birth defects, low birth weight, premature delivery, stillbirth, and neonatal death. Actual fetal/neonatal risks may be related to duration and severity of maternal hypertension. Untreated chronic hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, pre-eclampsia, delivery complications, stroke and myocardial infarction (ACOG 203 2019).

When treatment of hypertension in pregnancy is indicated, ACE inhibitors should generally be avoided due to their adverse fetal events; use in pregnant women should only be considered for cases of hypertension refractory to other medications (ACOG 203 2019).

ACE inhibitors should be avoided in sexually active females of reproductive potential not using effective contraception (ADA 2020). ACE inhibitors should generally be avoided for the treatment of hypertension in women planning a pregnancy; use should only be considered for cases of hypertension refractory to other medications (ACOG 203 2019).
