- ACE Inhibitors
Description
Angiotensin converting enzyme (ACE) inhibitors dilate arteries and veins by competitively inhibiting the conversion of angiotensin I to angiotensin II (a potent endogenous vasoconstrictor) and by inhibiting bradykinin metabolism; these actions result in preload and afterload reductions on the heart
ACE inhibitors also promote sodium and water excretion by inhibiting angiotensin-II induced aldosterone secretion; elevation in potassium may also be observed
ACE inhibitors also elicit renoprotective effects through vasodilation of renal arterioles
ACE inhibitors reduce cardiac and vascular remodeling associated with chronic hypertension, heart failure, and myocardial infarction
Indications
Indicated for the treatment of hypertension
Contraindications
Hypersensitivity to moexipril/other ACE inhibitors
History of hereditary or angioedema associated with previous ACE inhibitor treatment
Coadministration of neprilysin inhibitors (eg, sacubitril) with ACE inhibitors may increase angioedema risk; do not administer ACE inhibitors within 36 hr of switching to or from sacubitril/valsartan
Bilateral renal artery stenosis
Do not coadminister with aliskiren in patients with diabetes mellitus or with renal impairment (ie, GFR <60 mL/min/1.73 m²)

Warnings
Apheresis (LDL) with dextran sulfate, hypertrophic cardiomyopathy, collagen vascular disease, hemodialysis with high flux membrane, aortic stenosis
Less effective in African-Americans
Excessive hypotension if concomitant diuretics, hypovolemia, hyponatremia
Risk of hyperkalemia, especially with renal impairment, DM, or those taking concomitant K+-elevating drugs
Dual blockade of the renin angiotensin system with ARBs, ACE inhibitors, or aliskiren associated with increased risk for hypotension, hyperkalemia, and renal function changes (including acute renal failure) compared to monotherapy
ACE inhibition also causes increased bradykinin levels which putatively mediates angioedema
Coadministration with mTOR inhibitors (eg, temsirolimus) may increase risk for angioedema
Renal impairment may occur
Neutropenia/agranulocytosis reported
Cough may occur within the first few months
Cholestatic jaundice may occur
Use caution in severe aortic stenosis
Discontinue immediately if pregnant (see Contraindications and Black Box Warnings)
Renal impairment
Pregnancy and Lactation
Pregnancy Category: C (1st trimester); D (2nd & 3rd trimesters)
Discontinue as soon as pregnancy detected; during the second and third trimesters of pregnancy, drugs that act directly on the renin-angiotensin have been associated with fetal injury that includes hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death
Lactation: not known if excreted into breast milk; use caution
