Ramipril
Brand Name: Altace
Pregnancy Category C (first trimester), Pregnancy Category D (second and third trimesters)
Drug classes: Antihypertensive, Angiotensin-converting enzyme (ACE) inhibitor
Therapeutic actions
Ramipril blocks ACE from converting angiotensin I to angiotensin II, a powerful vasoconstrictor, leading to decreased BP, decreased aldosterone secretion, a small increase in serum potassium levels, and sodium and fluid loss; increased prostaglandin synthesis also may be involved in the antihypertensive action.
Indications
· Treatment of hypertension alone or in combination with thiazide-type diuretics
· Treatment of CHF in stable patients in the first few days after MI
· To decrease the risk of cardiovascular disease in patients at risk for developing CAD
Contraindications
· Contraindicated with allergy to ramipril, pregnancy (embryocidal in preclinical studies).
Adverse effects
Tachycardia, angina pectoris, MI, Raynaud's syndrome, CHF, hypotension in salt/volume depleted patients
Rash, pruritus, pemphigoid-like reaction, scalded mouth sensation, exfoliative dermatitis, photosensitivity, alopecia
Gastric irritation, aphthous ulcers, peptic ulcers, dysgeusia, cholestatic jaundice, hepatocellular injury, anorexia, constipation
Proteinuria, renal insufficiency, renal failure, polyuria, oliguria, urinary frequency
Neutropenia, agranulocytosis, thrombocytopenia, hemolytic anemia, pancytopenia
Cough, malaise, dry mouth, lymphadenopathy, angioedema
Drug Interactions:
· Exacerbation of cough if taken with capsaicin
· Increased serum levels and increased toxicity with lithium; monitor patient closely
Nursing considerations
· Administer 1 hr before or 2 hr after meals.
· Discontinue diuretic for 2–3 days before beginning therapy, if possible, to avoid severe hypotensive effect.
· Open capsules and sprinkle contents over a small amount of applesauce or mix in applesauce or water if patient has difficulty swallowing capsules. Mixture is stable for 24 hr at room temperature and 48 hr if refrigerated.
· Alert surgeon and mark chart that ramipril is being used; the angiotensin II formation subsequent to compensatory renin release during surgery will be blocked; hypotension may be reversed with volume expansion.
· Monitor patient closely for falling BP secondary to reduction in fluid volume (excessive perspiration and dehydration, vomiting, diarrhea) because excessive hypotension may occur.
· Reduce dosage in patients with impaired renal function.
