Perdix (UK), Univasc
Pharmacologic class: Angiotensin-converting enzyme (ACE) inhibitor
Therapeutic class: Antihypertensive
Pregnancy risk category C (first trimester), D (second and third trimesters)
Pregnancy risk category C (first trimester), D (second and third trimesters)
FDA Box Warning
• When used during second or third trimester of pregnancy, drug may cause fetal harm or death. Discontinue drug as soon as possible when pregnancy is detected.
Inhibits conversion of angiotensin I to the vasoconstrictor angiotensin II, inactivates bradykinin and other vasodilatory prostaglandins, increases plasma renin levels, and reduces aldosterone levels. Net effect is systemic vasodilation.
Tablets: 7.5 mg, 15 mg
⊘Indications and dosages
Adults: 7.5 mg P.O. daily 1 hour before a meal; may increase if blood pressure control is inadequate. Range is 7.5 mg to 30 mg/day in one or two divided doses given 1 hour before a meal.
• Renal impairment
• Concurrent diuretic therapy
• Hypersensitivity to drug
• Angioedema secondary to ACE inhibitor use
Use cautiously in:
• renal or hepatic impairment, hypovolemia, hyponatremia, aortic stenosis or hypertrophic cardiomyopathy, cardiac or cerebrovascular insufficiency
• family history of angioedema
• concurrent diuretic therapy
• black patients
• elderly patients
• pregnant or breastfeeding patients
• children (safety not established).
• Give 1 hour before meals (food reduces drug absorption).
• Adjust dosage, as ordered, according to blood pressure response.
CNS: dizziness, fatigue
CV: chest pain, peripheral edema
EENT: pharyngitis, sinusitis
GI: nausea, diarrhea
GU: urinary frequency
Respiratory: upper respiratory infection, increased cough
Skin: rash, flushing, angioedema
Other: fever, flulike symptoms, hypersensitivity reaction
Drug-drug.Allopurinol: increased risk of hypersensitivity reaction
Antacids: decreased moexipril absorption
Antihypertensives, general anesthetics, nitrates, phenothiazines: additive hypotension
Cyclosporine, indomethacin, potassium-sparing diuretics, potassium supplements, salt substitutes: hyperkalemia
Digoxin, lithium: increased blood levels of these drugs
Diuretics: excessive hypotension
Nonsteroidal anti-inflammatory drugs: blunted antihypertensive response
Drug-diagnostic tests.Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, bilirubin, blood urea nitrogen, creatinine, potassium: increased levels
Antinuclear antibody: positive titer
Sodium: decreased level
Drug-food.Salt substitutes containing potassium: hyperkalemia
Drug-behaviors.Acute alcohol ingestion: additive hypotension
• Monitor vital signs and neurologic and cardiovascular status.
• Assess respiratory status, staying alert for persistent dry cough.
• Evaluate for allergic reactions and angioedema.
• Know that moexipril monotherapy is less effective in black patients, who may need additional concurrent antihypertensives.
• Instruct patient to take 1 hour before a meal.
• Tell patient to report persistent dry cough and signs or symptoms of infection (especially upper respiratory infection).
• Advise patient to change position slowly (especially during first few days of therapy), to minimize hypotension and dizziness.
• Instruct patient to limit foods high in potassium and avoid salt substitutes containing potassium.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, foods, and behaviors mentioned above.

Adverse Reactions/Side Effects
Central nervous system
- cough (most frequent)
- hypotension (most frequent)
- chest pain
- impaired renal function
Fluid and Electrolyte
- angioedema (life-threatening)
- flu-like symptoms
Drug-Drug interactionExcessive hypotension may occur with concurrent use of diuretics.Additive hypotension with other antihypertensive agents.↑ risk of hyperkalemia with concurrent use of potassium supplements,potassium-sharing diuretics, or potassium-containing salt substitutes.↑ risk of hyperkalemia, renal dysfunction, hypotension, and syncope with concurrent use of angiotensin II receptor antagonists or aliskiren ; avoid concurrent use with aliskiren in patients with diabetes or CCr <60 mL/minNSAIDs and selective COX-2 inhibitors may blunt the antihypertensive effect and ↑ the risk of renal dysfunction.↑ levels and may ↑ the risk of lithium toxicity. Food significantly ↓ absorption. Administer moexipril 1 hr before meals.
Renal ImpairmentOral (Adults) CCr ≤40 mL/min—Initiate therapy at 3.75 mg once daily, may be titrated upward carefully to 15 mg/day.
Availability (generic available)
- Monitor BP and pulse frequently during initial dosage adjustment and periodically throughout therapy. Notify health care professional of significant changes.
- Monitor frequency of prescription refills to determine compliance.
- Assess patient for signs of angioedema (dyspnea, facial swelling).
- Lab Test Considerations: Monitor renal function. May cause ↑ BUN and serum creatinine.
- May cause hyperkalemia.
- Monitor CBC periodically during therapy in patients with collagen vascular disease and/or renal disease. May rarely cause agranulocytosis.
- May cause ↑ AST, ALT, alkaline phosphatase, serum bilirubin, and uric acid.
Potential Nursing DiagnosesDecreased cardiac output (Indications, Side Effects)
Deficient knowledge, related to medication regimen (Patient/Family Teaching)
Noncompliance (Patient/Family Teaching)
- Correct volume depletion, if possible, before initiation of therapy.
- Oral: Administer moexipril on an empty stomach, 1 hr before a meal.
- 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 ACE inhibitor therapy unless directed by health care professional.
- 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.
- Caution patient to avoid salt substitutes containing potassium, or foods containing high levels of potassium or sodium unless directed by health care professional (see ).
- 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.
- Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications, especially 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 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 women of childbearing age to use contraception and notify health care professional of pregnancy is planned or suspected.
- Emphasize the importance of follow-up examinations to evaluate effectiveness of medication.
- Decrease in BP without appearance of excessive side effects.
