    • Additive bradycardia may occur with beta blockers, diltiazem, and other antiarrhythmics.
    • Concurrent use of sympathomimetics may ↑ risk of arrthythmias.
  • Assessment- 
    • Monitor apical pulse for 1 full min before administering. Withhold dose and notify health care professional if pulse rate is <60 bpm in an adult, Also notify health care professional promptly of any significant changes in rate, rhythm, or quality of pulse.
    • Monitor BP and ECG throughout IV administration and 6 hr after each dose. Notify health care professional if bradycardia or new arrhythmias occur.
    • Observe IV site for redness or infiltration; extravasation can lead to tissue irritation and sloughing.

Patients receiving erythromycin or tetracycline, which kill gut bacteria, can develop toxicity on their usual doses of digoxin.
      • Observe for signs and symptoms of toxicity. In adults and older children, the first signs of toxicity usually include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and other arrhythmias.
      • Correction of arrhythmias resulting from digitalis toxicity may be attempted with lidocaine, quinidine, or propranolol. Temporary ventricular pacing may be useful in advanced heart block.
      • Treatment of life-threatening arrhythmias may include administration of digoxin immune Fab (Digibind), which binds to the digitalis glycoside molecule in the blood and is excreted by the kidneys.
  • Implementation- 
    • High Alert: Digoxin has a narrow therapeutic range. Medication errors associated with digoxin inclyde insufficient monitoring of digoxin levels. Have second practitioner independently check original order and dose calculations. Monitor therapeutic drug levels.
    • For rapid digitalization, the initial dose is higher than the maintenance dose; 50% of the total digitalizing dose is given initially. The remainder of the dose will be administered in 25% increments at 4–8 hr intervals.
    • When changing from parenteral to oral dose forms, dose adjustments may be necessary because of pharmacokinetic variations in percentage of digoxin absorbed
  • Evaluation/desired outcomes- 
    • Decrease in severity of HF.
    • Increase in cardiac output.
    • Decrease in ventricular response in atrial tachyarrhythmias.
    • Termination of paroxysmal atrial tachycardia.

    • Agents having anticholinergic properties (tricyclic antidepressants, antihistamines, phenothiazines) may ↓ absorption of translingual or sublingual nitroglycerin.
  • Assessment- 
    • Assess location, duration, intensity, and precipitating factors of patient's anginal pain.
    • Monitor BP and pulse before and after administration. Patients receiving IV nitroglycerin require continuous ECG and BP monitoring. Additional hemodynamic parameters may be monitored.
    • Lab Test Considerations:
      • May cause falsely ↑ serum cholesterol levels.
  • Implementations- 
    • PO: Administer dose 1 hr before or 2 hr after meals with a full glass of water for faster absorption. Sustained-release preparations should be swallowed whole; do not break, crush, or chew.
    • SL: Tablet should be held under tongue until dissolved. Avoid eating, drinking, or smoking until tablet is dissolved.
    • Translingual spray: 
      • Spray Nitrolingual under tongue. Spray Nitromist on or under tongue.
    • Topical: Sites of topical application should be rotated to prevent skin irritation. Remove patch or ointment from previous site before application.
      • Doses may be increased to the highest dose that does not cause symptomatic hypotension.
      • Apply ointment by using dose-measuring application papers supplied with ointment. Squeeze ointment onto measuring scale printed on paper. Use paper to spread ointment onto nonhairy area of skin (chest, abdomen, thighs; avoid distal extremities) in a thin, even layer, covering a 2–3-in. area. Do not allow ointment to come in contact with hands. Do not massage or rub in ointment; this will increase absorption and interfere with sustained action. Apply occlusive dressing if ordered.
      • Transdermal patches may be applied to any hairless site (avoid distal extremities or areas with cuts or calluses). Apply firm pressure over patch to ensure contact with skin, especially around edges. Apply a new dose unit if the first one becomes loose or falls off. Units are waterproof and not affected by showering or bathing. Do not cut or trim system to adjust dosage. Do not alternate between brands of transdermal products; dose may not be equivalent. Remove patches before MRI, cardioversion or defibrillation to prevent patient burns. Patch may be worn for 12–14 hr and removed for 10–12 hr at night to prevent development of tolerance.
  • Evaluation/desired outcome- 
    • Decrease in frequency and severity of anginal attacks.
      • Increase in activity tolerance. During long-term therapy, tolerance may be minimized by intermittent administration in 12–14 hr or 10–12 hr off intervals.
    • Controlled hypotension during surgical procedures.
    • Treatment of HF associated with acute MI.

        • Monitor CBC with differential prior to initiation of therapy, every 2 wk for the first 3 mo, and periodically for up to 1 yr in patients at risk for neutropenia (patients with renal impairment, or collagen-vascular disease) or at first sign of infection. Discontinue therapy if neutrophil count is <1000/mm3.
        • May cause false-positive test results for urine acetone.
  • Implementation- 
    • Correct volume depletion, if possible, before initiation of therapy due to possible precipitous drop in BP during first 1–3 hr following first dose.

Nesiritide (Natrecor)

Definition
  • Pregnancy Category- Category C
  • Ther. Class.- none assigned
  • Pharm. Class.- vasodilators (human B-type natriuretic peptide)
  • Indications-
    • Acutely decompensated HF in hospitalized patients who have dyspnea at rest or with minimal activity; has been used with digoxin, diuretics, and ACE inhibitors. Should not be used for intermittent outpatient infusion, scheduled repetitive use, as a diuretic or to improve renal function.
  • Action-
    •  Binds to guanyl cyclase receptors in vascular smooth muscle and endothelial cells, producing increased intracellular guanosine 3'5'-cyclic monophosphate (cGMP) and smooth muscle cell relaxation. cGMP acts as a "second messenger" to dilate veins and arteries.
    • Therapeutic Effect(s):
      • Dose-dependent reduction in pulmonary capillary wedge pressure (PCWP) and systemic arterial pressure in patients with heart failure with resultant decrease in dyspnea.
  • Contraindicated in:
    • Cardiogenic shock
    • Systolic BP <90 mm Hg
    • Low cardiac filling pressure, significant valvular stenosis, restrictive/subtractive cardiomyopathy, constrictive pericarditis/cardiac tamponade, or other conditions in which cardiac output is dependent on venous return.
  • Use Cautiously in:
    • Heart failure where renal function is dependent on activity of the renin/angiotensin/aldosterone system (may cause azotemia)
    • Cardiogenic shock (should not be used as primary therapy)
  • Adverse rxns/side effects-
    •  CNS: anxiety, confusion, dizziness, headache, hypotension (dose related), insomnia

  • Assessment-
    • Monitor BP, pulse, ECG, respiratory rate, cardiac index, PCWP, and central venous pressure frequently during administration. May cause hypotension, especially in patients with a BP <100 mm Hg. Reduce dose or discontinue nesiritide if patient develops hypotension. Hypotension may cause renal compromise. Use IV fluids and changes in body position to support BP if symptomatic hypotension occurs. Nesiritide may be restarted at a dose reduced by 30% with no bolus administration once patient is stabilized. Hypotension may be prolonged for hours, requiring a period of monitoring prior to restarting administration.
    • Monitor intake and output and weigh daily. Assess for decrease in signs of HF (dyspnea, rales/crackles, peripheral edema, weight gain).
    • Lab Test Considerations:
      • Monitor BUN and serum creatinine. May cause ↑ in serum creatinine; ↑ serum creatinine may be dose-related.
  • Implementations-
    • High Alert: Intravenous vasoactive medications have an increased potential for causing harm. Have second practitioner independently check original order, dose calculations, and infusion pump settings. Administer only in settings where BP can be closely monitored.
  • Evaluation/desired effects-
    • Improvement in dyspnea and reduction in mean PCWP in patients with decompensated HF.
