Discontinue as soon as possible when pregnancy is detected; affects renin-angiotensin system causing oligohydramnios, which may result in fetal injury and/or death
Contraindications
Hypersensitivity to this product or any other ACE inhibitor
Angioedema associated with prior ACE inhibitor treatment
Coadministration with aliskiren in patients with diabetes mellitus
Cautions
As angiotensin-converting enzyme inhibitors affect metabolism of eicosanoids and polypeptides, including endogenous bradykinin, patients receiving ACE inhibitors (including this drug) may be subject to a variety of adverse reactions, some of them serious
Presumably due to the inhibition of degradation of endogenous bradykinin, persistent nonproductive cough has been reported with all ACE inhibitors, always resolving after discontinuation of therapy; ACE inhibitor-induced cough should be considered in the differential diagnosis of cough
Since fosinopril is primarily metabolized by hepatic and gut wall esterases to its active moiety, fosinopril at, patients with impaired liver function could develop elevated plasma levels of unchanged fosinopril; in a study in patients with alcoholic or biliary cirrhosis, the extent of hydrolysis was unaffected, although the rate was slowed; in these patients, the apparent total body clearance of this drug was decreased and the plasma AUC approximately doubled
In patients undergoing surgery or during anesthesia with agents that produce hypotension, fosinopril will block the angiotensin II formation that could otherwise occur secondary to compensatory renin release; hypotension that occurs as a result of this mechanism can be corrected by volume expansion
Recent clinical observations have shown an association of hypersensitivity-like (anaphylactoid) reactions during hemodialysis with high-flux dialysis membranes (eg, AN69) in patients receiving ACE inhibitors as medication; in these patients, consideration should be given to using a different type of dialysis membrane or a different class of medication
Rarely, ACE Inhibitors have been associated with a syndrome that starts with cholestatic jaundice and progresses to fulminant hepatic necrosis and (sometimes) death; the mechanism of this syndrome is not understood
Patients receiving ACE inhibitors who develop jaundice or marked elevations of hepatic enzymes should discontinue the ACE inhibitor and receive appropriate medical follow-up
Anaphylactoid reactions
- Angioedema involving extremities, face, lips, mucous membranes,tongue, glottis or larynx reported in patients treated with ACE inhibitors; if angioedema involves the tongue, glottis or larynx, airway obstruction may occur and be fatal; if laryngeal stridor or angioedema of the face, lips, mucous membranes, tongue, glottis or extremities occurs, treatment with this drug should be discontinued and appropriate therapy instituted immediately
- Where there is involvement of the tongue, glottis, or larynx, likely to cause airway obstruction, appropriate therapy, eg, subcutaneous epinephrine solution 1:1000 (0.3 mL to 0.5 mL) should be promptly administered
Hypotension
- Therapy can cause symptomatic hypotension; like other ACE inhibitors, fosinopril has been only rarely associated with hypotension in uncomplicated hypertensive patients
- Symptomatic hypotension is most likely to occur in patients who have been volume- and/or salt-depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting
- Volume and/or salt depletion should be corrected before initiating therapy; in patients with heart failure, with or without associated renal insufficiency, ACE inhibitor therapy may cause excessive hypotension, which may be associated with oliguria or azotemia and, rarely, with acute renal failure and death
- In such patients, therapy should be started under close medical supervision; they should be followed closely for first 2 weeks of treatment and whenever dose of fosinopril or diuretic is increased
- Consideration should be given to reducing the diuretic dose in patients with normal or low blood pressure who have been treated vigorously with diuretics or who are hyponatremic hypotension occurs, the patient should be placed in a supine position, and, if necessary, treated with intravenous infusion of physiological saline; treatment usually can be continued following restoration of blood pressure and volume
Neutropenia/agranulocytosis
- Another angiotensin-converting enzyme inhibitor, captopril, has been shown to cause agranulocytosis and bone marrow depression, rarely in uncomplicated patients, but more frequently in patients with renal impairment, especially if they also have a collagen-vascular disease such as systemic lupus erythematosus or scleroderma
- Available data from clinical trials of fosinopril are insufficient to show that fosinopril does not cause agranulocytosis at similar rates; monitoring of white blood cell counts should be considered in patients with collagen-vascular disease, especially if the disease is associated with impaired renal function
Renal function
- As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals; in patients with severe congestive heart failure whose renal function may depend on activity of renin-angiotensin-aldosterone system, treatment with angiotensin-converting enzyme inhibitors, including this drug may be associated with oliguria and/or progressive azotemia and (rarely) with acute renal failure and/or death
- In hypertensive patients with renal artery stenosis in a solitary kidney or bilateral renal artery stenosis, increases in blood urea nitrogen and serum creatinine may occur; experience with another angiotensin-converting enzyme inhibitor suggests that these increases are usually reversible upon discontinuation of ACE inhibitor and/or diuretic therapy
- In such patients, renal function should be monitored during first few weeks of therapy; some hypertensive patients with no apparent pre-existing renal vascular disease have developed increases in blood urea nitrogen and serum creatinine, usually minor and transient, especially when this drug has been given concomitantly with a diuretic; this is more likely to occur in patients with pre-existing renal impairment; dosage reduction and/or discontinuation of the diuretic may be required
- Evaluation of patients with hypertension or heart failure should always include assessment of renal function; impaired renal function decreases total clearance of fosinoprilat and approximately doubles AUC; in general, no adjustment of dosing is needed; however, patients with heart failure and severely reduced renal function may be more sensitive to the hemodynamic effects (eg, hypotension) of ACE inhibition
Hyperkalemia
- In clinical trials, hyperkalemia (serum potassium > 10% above upper limit of normal) reported in hypertensive patients receiving this drug; in most cases, these were isolated values that resolved despite continued therapy
- In clinical trials, 0.1% of patients (two patients) were discontinued from therapy due to elevated serum potassium; risk factors for development of hyperkalemia include renal insufficiency, diabetes mellitus, and concomitant use of potassium-sparing diuretics, potassium supplements, and/or potassium-containing salt substitutes, which should be used cautiously, if at all, with this drug
Pregnancy & Lactation
Pregnancy
ACE inhibitors can cause fetal and neonatal morbidity and death when administered to pregnant women; several dozen cases reported in the world literature; when pregnancy is detected, ACE inhibitors should be discontinued as soon as possible
The use of ACE inhibitors during second and third trimesters of pregnancy has been associated with fetal and neonatal injury, including hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death
Oligohydramnios also reported, presumably resulting from decreased fetal renal function; oligohydramnios in this setting has been associated with fetal limb contractures, craniofacial deformation, and hypoplastic lung development
Prematurity, intrauterine growth retardation, and patent ductus arteriosus also reported, although not clear whether these occurrences were due to ACE-inhibitor exposure
These adverse effects do not appear to have resulted from intrauterine ACE-inhibitor exposure limited to first trimester; mothers whose embryos and fetuses are exposed to ACE inhibitors only during first trimester should be so informed
Nonetheless, when patients become pregnant, physicians should make every effort to discontinue use of fosinopril as soon as possible; rarely (probably less often than once in every thousand pregnancies), no alternative to ACE inhibitors will be found; in these rare cases, the mothers should be apprised of potential hazards to their fetuses, and serial ultrasound examinations performed to assess intraamniotic environment
If oligohydramnios is observed, fosinopril should be discontinued unless considered life-saving for the mother; contraction stress testing (CST), a non-stress test (NST), or biophysical profiling (BPP) may be appropriate, depending upon week of pregnancy
Patients and physicians should be aware, however, that oligohydramnios may not appear until after fetus has sustained irreversible injury; infants with histories of in-utero exposure to ACE inhibitors should be closely observed for hypotension, oliguria, and hyperkalemia
If oliguria occurs, attention should be directed toward support of blood pressure and renal perfusion; exchange transfusion or dialysis may be required as a means of reversing hypotension and/or substituting for disordered renal function
Fosinopril is poorly dialyzed from circulation of adults by hemodialysis and peritoneal dialysis.; there is no experience with any procedure for removing fosinopril from neonatal circulation
Animal data
- When fosinopril was given to pregnant rats at doses about 80 to 250 times (on mg/kg basis) maximum recommended human dose, three similar orofacial malformations and one fetus with situs inversus were observed among the offspring; no teratogenic effects of fosinopril were seen in studies in pregnant rabbits at doses up to 25 times (on mg/kg basis) the maximum recommended human dose
Lactation
Ingestion of 20 mg daily for three days resulted in detectable levels of this drug in breast milk; this drug should not be administered to nursing mothers
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Angiotensin converting enzyme (ACE) inhibitors dilate arteries and veins by competively 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
