Ace Inhibitors Flashcards
Ace inhibitors
Good results for HF in combo with digoxin and diuretics promote longer survival. This is the first line drug for HF. (replaced digoxin which was previously used as a first line drug)
Ace inhibitor: Action
Ace inhibitor Action: interferes with the RAAS by inhibiting the enzyme that converts angiotensin I to angiotensin II. This decreases aldosterone release by the adrenal cortex, preventing sodium and water retention. Also reduces peripheral arterial resistance without affecting the heart rate and CO. The result, in a patient with hypertension, is a decreased blood pressure.
Ace inhibitor: more about the action
ACE inhibitors prevent sodium and water resorption in the kidney, but potassium is resorbed, so the nurse needs to monitor potassium levels.
Ace inhibitor: Uses
Hypertension Heart Failure Acute MI (slows the progression of L ventricular hypertrophy post MI) Patients at high risk for CV events, diabetic retinopathy, kidney diseases Drug of choice for HF patients with HTN Renal protective for DM patients
Ace inhibitor: Side effects
Dizziness Mood changes Head ache Dry, nonproductive cough first dose hypotension Dysgensia (loss of taste) Rash, Pruritis Anemia Neutropenia, Thrombocytosis Agranulocytosis, Hyperkalemia Fatigue Syncope
Ace inhibitor: Angioedema (side effect)
Angioedema (itching and swelling of the face and neck) If the drug is not stopped, patient is at a high risk of further episodes with serious morbidity (intubation). Risk of angioedema is 5 times higher in black people than whites. Can also, on rare occasions, cause visceral angioedema which is localized edema and capillary permeability in the gut causing pain, n/v, and/or diarrhea.
Ace inhibitor: Interactions
NSAIDS (increase BP)
Diuretics
Other antihypertensives (increased antihypertensive effect)
Ace inhibitor: Drugs
captopril (Capoten)
Ace inhibitor
captopril (Capoten)
short half life, so this is good for titrating acutely ill patient.
Give on an empty stomach
Ace inhibitor: Drugs
enalapril (Vasotec)
enalapril (Vasotec)
PO, IV
This is a prodrug
Ace inhibitor: Drugs
ramipril (Altace)
ramipril (Altace)
effective
Also reduced the new development of DM by 30%, the first drug to be effective in this role.
More Ace inhibitor drug types
fosinopril [Monopril]*
lisinopril [Zestril]*
benazepril [Lotensin]
Ace inhibitor: Nursing considerations
Get baseline pulse and BP.
Monitor for hypotension.
Monitor liver fx, renal fx, and K+ q month for first 3 months.
If angioedema occurs - stop drug, call MD, may need emergency Tx.
