Use Cautiously in:

• Renal impairment, hypovolemia, hyponatremia, or concurrent diuretic therapy (initial dosage ↓ recommended)
• Black patients (less effective as monotherapy in hypertension; may require additional therapy; higher risk of angioedema)
• Surgery/anesthesia (hypotension may be exaggerated)
• Women of reproductive potential
• Pedi: Children <6 yr (safety and effectiveness not established)

Exercise Extreme Caution in:

• Family history of angioedema.

CV: hypotension, chest pain.

Derm: rash.

F and E: hyperkalemia.

GI: abdominal pain, diarrhea, nausea, vomiting.

GU: erectile dysfunction, renal impairment.

Neuro: dizziness, fatigue, headache, weakness.

Resp: cough.
Misc: ANGIOEDEMA.

Drug-Drug:

• Concurrent use with sacubitril ↑ risk of angioedema; concurrent use contraindicated; do not administer within 36 hr of switching to/from sacubitril/valsartan.
• Excessive hypotension may occur with concurrent use of diuretics.
• Additive hypotension with other antihypertensive agents.
• ↑ risk of hyperkalemia with concurrent use of potassium supplements, potassium-sparing diuretics, or potassium-containing salt substitutes.
• ↑ risk of hyperkalemia, renal dysfunction, hypotension, and syncope with concurrent use of angiotensin II receptor blockers or aliskiren; avoid concurrent use with aliskiren in patients with diabetes or CCr <60 mL/min; avoid concurrent use with angiotensin II receptor blockers
• NSAIDs and selective COX-2 inhibitors may blunt the antihypertensive effect and ↑ the risk of renal dysfunction.
• ↑ levels and may ↑ the risk of lithium toxicity.
• ↑ risk of angioedema with temsirolimus, sirolimus, or everolimus.

(Generic available)

• Oral solution: 1 mg/mL;

Hypertension

• PO (Adults): 10 mg once daily, can be ↑ up to 20–40 mg/day (initiate therapy at 5 mg/day in patients receiving diuretics).

Heart Failure

• PO (Adults): 5 mg once daily, may be titrated every 2 wk up to 40 mg/day; initiate therapy at 2.5 mg once daily in patients with hyponatremia (serum sodium <130 mEq/L).

Acute Myocardial Infarction

• PO (Adults): 5 mg once daily for 2 days, then 10 mg daily.

Prinivil, Qbrelis, Zestril

• Angiotensin-converting enzyme (ACE) inhibitors block the conversion of angiotensin I to the vasoconstrictor angiotensin II. ACE inhibitors also prevent the degradation of bradykinin and other vasodilatory prostaglandins. ACE inhibitors also ↑ plasma renin levels and ↓ aldosterone levels. Net result is systemic vasodilation.

• Lowering of BP in hypertensive patients.
• Increased survival and decreased symptoms in patients with HF.
• Increased survival after MI.

Therapeutic Classification: antihypertensives

Pharmacologic Classification: ace inhibitors

Absorption: 25% absorbed following oral administration (much inter-individual variability).

Distribution: Crosses the placenta; may enter breast milk.

Metabolism/Excretion: 100% eliminated by the kidneys.

Half-life: 12 hr (↑ in renal impairment).

(effect on BP-single dose†)

†Full effects may not be noted for several weeks.

• Instruct patient to take medication as directed at the same time each day, even if feeling well. Take missed doses as soon as remembered but not if almost time for next dose. Do not double doses. Warn patient not to discontinue lisinopril unless directed by health care professional.
  • Caution patient to avoid salt substitutes containing potassium or foods containing high levels of potassium or sodium unless directed by health care professional. See Appendix M.
  • Caution patient to change positions slowly to minimize orthostatic hypotension. Use of alcohol, standing for long periods, exercising, and hot weather may increase orthostatic hypotension.
  • Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications, especially NSAIDs and cough, cold, or allergy remedies.
  • May cause dizziness. Caution patient to avoid driving and other activities requiring alertness until response to medication is known.
  • Advise patient to inform health care professional of medication regimen before treatment or surgery.
  • Instruct patient to notify health care professional immediately if rash; mouth sores; sore throat; fever; swelling of hands or feet; irregular heart beat; chest pain; dry cough; hoarseness; swelling of face, eyes, lips, or tongue; or if difficulty swallowing or breathing occurs. Persistent dry cough may occur and may not subside until medication is discontinued. Consult health care professional if cough becomes bothersome. Also notify health care professional if nausea, vomiting, or diarrhea occurs and continues.
  • Advise diabetic patients to monitor blood glucose closely, especially during first mo of therapy; may cause hypoglycemia.
• May cause fetal harm. Advise females of reproductive potential to use effective contraception and notify health care professional if pregnancy is planned or suspected or if breastfeeding. If pregnancy is detected, discontinue lisinopril as soon as possible.
• Emphasize the importance of follow-up examinations to evaluate effectiveness of medication.
• Hypertension: Encourage patient to comply with additional interventions for hypertension (weight reduction, low sodium diet, discontinuation of smoking, moderation of alcohol consumption, regular exercise, and stress management). Medication controls but does not cure hypertension.
  • Instruct patient and family on correct technique for monitoring BP. Advise them to check BP at least weekly and to report significant changes to health care professional.
