Hypertension: Treatment of hypertension, either alone or in combination with other antihypertensive agents
The 2014 guideline for the management of high blood pressure in adults (Eighth Joint National Committee [JNC 8]) recommends initiation of pharmacologic treatment to lower blood pressure for the following patients:
- Patients ≥60 years of age with systolic blood pressure (SBP) ≥150 mm Hg or diastolic blood pressure (DBP) ≥90 mm Hg. Goal of therapy is SBP <150 mm Hg and DBP <90 mm Hg.
- Patients <60 years of age with SBP ≥140 mm Hg or DBP is ≥90 mm Hg. Goal of therapy is SBP <140 mm Hg and DBP <90 mm Hg.
- Patients ≥18 years of age with diabetes and SBP ≥140 mm Hg or DBP ≥90 mm Hg. Goal of therapy is SBP <140 mm Hg and DBP <90 mm Hg.
- Patients ≥18 years of age with chronic kidney disease (CKD) and SBP ≥140 mm Hg or DBP ≥90 mm Hg. Goal of therapy is SBP <140 mm Hg and DBP <90 mm Hg.
In patients with CKD, regardless of race or diabetes status, the use of an ACE inhibitor (ACEI) or angiotensin receptor blocker (ARB) as initial therapy is recommended to improve kidney outcomes. In the general nonblack population (without CKD) including those with diabetes, initial antihypertensive treatment should consist of a thiazide-type diuretic, calcium channel blocker, ACEI, or ARB. In the general black population (without CKD) including those with diabetes, initial antihypertensive treatment should consist of a thiazide-type diuretic or a calcium channel blocker instead of an ACEI or ARB.
Heart failure: Adjunctive treatment of heart failure (HF)
The ACCF/AHA 2013 heart failure guidelines recommend the use of ACE inhibitors, along with other guideline directed medical therapies, to prevent heart failure in patients with a reduced ejection fraction who have a history of MI (Stage B HF), to prevent HF in any patient with a reduced ejection fraction (Stage B HF), or to treat those with HF and reduced ejection fraction (Stage C HFrEF) (ACCF/AHA [Yancy 2013]).
Hypersensitivity to fosinopril, any other ACE inhibitor, or any component of the formulation; angioedema related to previous treatment with an ACE inhibitor; concomitant use with aliskiren in patients with diabetes mellitus
When pregnancy is detected, discontinue fosinopril as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.
Heart failure: Oral: Per the manufacturer: Initial: 10 mg once daily (5 mg once daily if moderate to severe renal dysfunction is present or if aggressively diuresed); increase dose as needed and as tolerated over several weeks. Usual dosage range: 20 to 40 mg once daily (maximum dose: 40 mg once daily). If hypotension, orthostasis, or azotemia occurs during titration, consider decreasing concomitant diuretic dose, if any.
ACCF/AHA 2013 heart failure guidelines: Initial: 5 to 10 mg once daily. Target dose: 40 mg once daily (Yancy 2013).
Hypertension: Oral: Initial: 10 mg once daily; maximum dose: 80 mg once daily. May need to divide the dose into two if trough effect is inadequate. If patient is receiving a diuretic prior to initiation, consider discontinuation of the diuretic to reduce likelihood of hypotension, if possible 2 to 3 days before initiation of therapy. If blood pressure response is inadequate, resume diuretic therapy carefully. Usual dose range (ASH/ISH [Weber 2014]): 10 to 40 mg daily.
HIV-associated nephropathy (HIVAN) (off-label use): Oral: 10 mg once daily (Wei 2003).
Refer to adult dosing.
Hypertension: Children ≥6 years and Adolescents >50 kg: Oral: Initial: 5 to 10 mg once daily (maximum: 40 mg once daily)
Moderate-severe impairment: Initial dose reduction to 5 mg once daily recommended for heart failure patients. No other dose adjustments are required; hepatobiliary elimination partially compensates for diminished renal elimination.
Hemodialysis: Poorly dialyzed; supplemental dose not required (Gehr, 1993)
Peritoneal dialysis: Poorly dialyzed; supplemental dose not required (Gehr, 1991)

In patients with end-stage renal disease (ESRD) (creatinine clearance <10 mL/minute/1.73 m2), fosinoprilat total body clearance is decreased ~50%.
In patients with alcoholic or biliary cirrhosis, the rate of fosinoprilat formation is slowed, its total body clearance decreased, and its AUC approximately doubled.
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; 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 patients 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 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.
Disease-related concerns:
- Aortic stenosis: Use with caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia.
- 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.
- Hepatic impairment: Use with caution; fosinopril undergoes hepatic and gut wall metabolism to its active form (fosinoprilat) and may accumulate in hepatic impairment. In patients with alcoholic or biliary cirrhosis, the rate of fosinoprilat formation was slowed, its total body clearance decreased, and its AUC approximately doubled.
- 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 preexisting 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:
- Pregnancy: [U.S. 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.
Other warnings/precautions:
- Surgery: 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).
D
[U.S. 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. Fosinopril crosses the placenta. 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. Teratogenic effects may occur following maternal use of an ACE inhibitor during the first trimester, although this finding may be confounded by maternal disease. Because adverse fetal events are well documented with exposure later in pregnancy, ACE inhibitor use in pregnant women is not recommended (Seely 2014; Weber 2014). 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 itself is also associated with adverse events in the fetus/infant and mother. ACE inhibitors are not recommended for the treatment of uncomplicated hypertension in pregnancy (ACOG 2013) and they are specifically contraindicated for the treatment of hypertension and chronic heart failure during pregnancy by some guidelines (Regitz-Zagrosek 2011). In addition, ACE inhibitors should generally be avoided in women of reproductive age (ACOG 2013). If treatment for hypertension or chronic heart failure in pregnancy is needed, other agents should be used (ACOG 2013; Regitz-Zagrosek 2011).
Competitive inhibitor of angiotensin-converting enzyme (ACE); prevents conversion of angiotensin I to angiotensin II, a potent vasoconstrictor; results in lower levels of angiotensin II which causes an increase in plasma renin activity and a reduction in aldosterone secretion; a CNS mechanism may also be involved in hypotensive effect as angiotensin II increases adrenergic outflow from CNS; vasoactive kallikreins may be decreased in conversion to active hormones by ACE inhibitors, thus reducing blood pressure
