Renal Dose Adjustment (Based on CrCl)
- <30 mL/min: 2.5 mg PO daily
- Hemodialysis: No supplement
Hepatic Dose Adjustment
- Hepatic impairment: Dose adjustments not defined
- ACE inhibitors can cause fetal/neonatal morbidity and death when administered to pregnant women
- ACE inhibitors may cause angioedema of the head and neck, including the tongue, lips, eyes, or throat
- Assess renal and hepatic function prior and periodically throughout therapy. Monitor serum potassium levels
- Assess heart failure patient for evidence of worsening failure (eg, daily weights, evaluation of peripheral edema, shortness of breath)
- Severely salt- or volume-depleted patients or those with heart failure may experience significant decreases in BP especially after first dose. Monitor closely for 2 hrs or more after initial dose and during first 2 wks of therapy
- Rarely, ACE inhibitors have been associated with a syndrome that starts with cholestatic jaundice and progresses to fulminant hepatic necrosis and sometimes death
- Neutropenia and agranulocytosis have occurred. Risk appears to be greater with renal dysfunction, heart failure, or immunosuppression
- Patients with a history of airway surgery may have a higher risk of airway obstruction
- Assess renal and hepatic function prior and periodically throughout therapy
- Monitor serum potassium levels
- Evaluation of patients with HTN or heart failure should always include assessment of renal function
- Monitor WBC if collagen vascular disease, especially if renal impairment
- Monitor BUN/Cr at baseline, then periodically, or more frequently if CHF, renal artery stenosis
Cautions: Use cautiously in
- Renal impairment
- Renal artery stenosis
- CAD
- Aortic stenosis
- Cerebrovascular disease
- Collagen vascular disease
- Hypotension
- Hyponatremia
- Volume depletion
- Severe CHF
- Hypertrophic cardiomyopathy
- Elderly patients
- Black patients
- Surgery/anesthesia (hypotension may be exaggerated)
- Dialysis with high-flux membranes
- CAD
- Aortic stenosis
- Cerebrovascular disease
- Collagen vascular disease
- Hypotension
- Volume depletion
- Severe CHF
- Hypertrophic cardiomyopathy
- Elderly patients
- Black patients
- Surgery/anesthesia (hypotension may be exaggerated)
- Dialysis with high-flux membranes
- Insect venom allergy, hymenoptera venom immunotherapy
Pregnancy Category:C (D in second and third trimesters)
Breastfeeding: Enalapril is excreted in breast milk in low levels; hence it would not be expected to cause any adverse effects in breastfed infants. This information is based upon LactMed database (available at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?LACT last accessed 15 July 2010)
