When pregnancy is detected, discontinue moexipril as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.
Hypertension , chronic:
Note: For patients who warrant combination therapy (BP >20/10 mm Hg above goal or suboptimal response to initial monotherapy), may use with another appropriate agent (eg, long-acting dihydropyridine calcium channel blocker or thiazide diuretic) (ACC/AHA [Whelton 2018]).
Oral: Initial: 3.75 to 7.5 mg once daily; evaluate response after approximately 2 to 4 weeks and titrate dose in 1-step increments (eg, increase the daily dose by doubling) as needed, up to 30 mg/day in 1 or 2 divided doses. Patients with severe asymptomatic hypertension and no signs of acute end organ damage should be evaluated for medication titration within 1 week (ACC/AHA [Whelton 2018]; Mann 2021).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Moexipril may be confused with Monopril
Use may be associated with increased blood urea nitrogen and increased serum creatinine, resulting in oliguria and acute kidney injury (AKI). Increases in serum creatinine are expected due to pharmacologic mechanism and generally stabilize within 20% to 30% of the baseline; higher increases may indicate high efferent tone (such as with hypovolemia, congestive heart failure, or renal artery stenosis) (Ref).
Mechanism: Related to pharmacologic action; inhibits efferent arteriolar vasoconstriction, which can lead to a reduction in the glomerular filtration rate (GFR). Kidney hypoperfusion from systemic hypotension may also occur (Ref).
Onset: Intermediate; increases in serum creatinine generally occur within 2 weeks of initiation and stabilize within 2 to 4 weeks (Ref). However, more immediate increases can occur in patients with other risk factors for AKI (Ref).
Risk factors:
• Patients with low renal blood flow whose GFR is dependent on efferent arteriolar vasoconstriction by angiotensin II including (Ref):
- Low effective circulating volume (sodium or volume depletion)
- Congestive heart failure
- Hypotension or shock
- Renal artery stenosis
• High dose at initiation (Ref)
• Older patients (Ref)
• Preexisting kidney impairment (Ref)
• Concurrent diuretic and/or nonsteroidal anti-inflammatory drug use (Ref)
Angioedema may occur rarely; edema may manifest in the head and neck (potentially compromising airway) or the intestine (presenting as abdominal pain). Use is contraindicated in patients with idiopathic or hereditary angioedema or previous angioedema associated with any angiotensin-converting enzyme inhibitors or neprilysin inhibitors (Ref).
Mechanism: Related to pharmacologic action (ie, increased bradykinin and substance P, vascular permeability, vasodilation) (Ref)
Onset: Varied; may occur at any time during treatment. Most cases occur within the first week of therapy but may also occur years after therapy (Ref).
Risk factors:
• Black patients (estimated 4- to 5-fold higher risk); the mechanism for this is not completely understood but may be related to genetic variants) (Ref)
• Females (Ref)
• Smoking history (Ref)
• Previous history of angioedema (Ref)
• Age >65 years (Ref)
• Seasonal allergies (Ref)
• Concurrent use of mechanistic target of rapamycin (mTOR) inhibitors (eg, everolimus) (Ref)
• Concurrent use of neprilysin inhibitor (contraindicated)
A dry, hacking, nonproductive cough that is typically associated with tickling or scratching in the throat may occur with angiotensin-converting enzyme inhibitors (ACEI) in adult and pediatric patients (Ref). Recurrence is likely with rechallenge (Ref). Resolution of cough typically occurs 1 to 4 weeks after ACEI discontinuation but may persist for up to 3 months (Ref).
Mechanism: Various proposed mechanisms. May be related to pharmacologic action (increase in bradykinin and substance P, resulting in accumulation in the lungs and bronchoconstriction) (Ref).
Onset: Varied; within hours to 4 weeks after initiation but can be delayed for up to 6 months (Ref)
Risk factors:
• Females (Ref)
• Possibly certain genetic variants (some of which may be independent of the bradykinin pathway) (Ref)
Hyperkalemia (elevated serum potassium) may occur on therapy with angiotensin converting enzyme inhibitors (ACEI), including moexipril (Ref).
Mechanism: Related to pharmacologic action; inhibits formation of circulating angiotensin II, which leads to efferent arteriole vasodilation and subsequent lowering of glomerular filtration rate, which lowers potassium elimination. Additionally, interferes with the generation and release of aldosterone from the adrenal cortex, leading to an impairment of potassium excretion from the kidney (Ref).
Risk factors:
• Disease states associated with hyperkalemia (congestive heart failure, diabetes mellitus, chronic kidney disease) (Ref)
• Concurrent use of medications which cause hyperkalemia (ACEI, angiotensin II receptor antagonists, spironolactone, nonsteroidal anti-inflammatory drugs, beta blockers, heparin, tacrolimus, cyclosporine) (Ref)
• Acute kidney injury (elevated BUN and/or serum creatinine) (Ref)
• High dietary intake of potassium or concomitant use of potassium supplements (including potassium-containing salt substitutes) (Ref)
• Baseline elevated potassium level (≥5 mmol/L) (Ref)

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.
Concerns related to adverse effects:
• Hypersensitivity reactions: Anaphylaxis/nonimmune anaphylaxis can occur with ACE inhibitors. Severe nonimmune anaphylaxis 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 nonimmune anaphylaxis 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.
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.
• Hypertrophic cardiomyopathy with left ventricular outflow tract obstruction: Use 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]).
• 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.
Special populations:
• Race/Ethnicity: In Black patients, the BP-lowering effects of ACE inhibitors may be less pronounced. The exact mechanism is not known; differences in the renin-angiotensin-aldosterone system, low renin levels, and salt sensitivity more commonly found in Black patients may contribute (Brewster 2013; Helmer 2017).
• 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]).

Food reduces moexiprilat's Cmax and AUC by 70% to 80% and 40% to 50%, respectively. Management: Take on an empty stomach 1 hour before a meal.
Avoid use of angiotensin-converting enzyme (ACE) inhibitor therapy in patients who may become pregnant and who are not using effective contraception (ADA 2021).
ACE inhibitors should generally be avoided for the treatment of hypertension in patients planning to become pregnant; use should only be considered for cases of hypertension refractory to other medications (ACOG 203 2019).
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 2018]).
[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).
It is not known if moexipril is present in breast milk.
The manufacturer recommends that caution be exercised when administering moexipril to breastfeeding women.
