Q

Phosphodiesterase Inhibitors

Common Examples: Milrinone (Primacor) Inamrinone (Inocor)

A

Indicated for the short-term management of heart failure.

  • Adverse effects include ventricular arrhythmias, hypotension, chest pain, HA, hypokalemia, tremors and thrombocytopenia.
  • Due to risk of toxicity theses are generally reserved for patients who do not respond to cardiac glycosides ore ACE inhibitors

Q

Cardiac Glycosides

A

Digoxin (Lanoxin, Digitek)

Indicated for the treatment of heart failure and dysrhythmias

  • Monitor Digoxin levels, therapeutic levels should be between 0.5- 2ng/ml.
  • Monitor K+, low serum potassium levels can increase the potential for toxicity.
  • Monitor pulse and teach patient to take their pulse. Hold for pulse < 60 BPM in adults.
  • Administer IV doses slowly over 5 minutes
  • A loading or “Digitalizing” dose may be given to get the serum levels within therapeutic range.
  • Common adverse effects include fatigue, anorexia and bradycardia. Monitor for signs of toxicity which include: HA, vertigo, photophobia, yellow-green halos, tachycardia and AV heart block
  • Antidote: Digibind

Q

Direct vasodilator s

A

Nesiritide (Natrecor)

Indicated for acute treatment of heart failure in patients with dyspnea at rest and/or minimal activity.

  • Common adverse effects include cardiac arrhythmias, hypotension, HA, fainting, and anxiety.
  • Reduce dose or stop administration with hypotension
  • Obtain a baseline creatinine level and continue to monitor, can be nephrotoxic with acutely decompensated heart failure.

Q

Organic nitrate/dilators

A

Nitroglycerin (Nitro-Bid), Isosorbide (Isordi)

Indicated for the treatment of stable and unstable angina. Rapid acting forms are indicated for the management of acute angina episodes and long acting forms are used for the prevention of angina attacks.

  • HA is the most commonly reported adverse effect, others include hypotension, tachycardia and contact dermatitis with topical forms.
  • Contraindicated with preexisting hypotension, head trauma or increased intracranial pressure, and pericardial tamponaade. *Adequate hydration status required for administration
  • For IV administration: use IV pump, hold for systolic BP < 100
  • For sublingual administration: store in dark, light resistant container, replace supply every 6 months, may administer up to 3 tabs SL
  • For topical administration: apply with gloves, use non-hairy sites and rotate sites, avoid lower extremities

Q

Beta-adrenergic Antagonists (Beta Blockers)

A

Common Examples:
Atenlol (Tenormin), Metoprolol (Lopressor), Propanolol (Inderal)

Indicated for the treatment of angina, particularly angina caused by exercise. Mainstay treatment for the management of hypertension, cardiac dysrhythmias and MI.

Unlabeled uses include migraines, and tachycardia associated with stage fright.

  • Well tolerated at low doses
  • Adverse effects include: bradycardia, hypotension, second and third degree heart block, fatigue, lethargy, depression, wheezing, dyspnea, impotence and decreased libido, altered glucose and lipid metabolism.
  • HoldforHR<60
  • Withdraw gradually to avoid rebound hypertension, angina and MI.
  • Periodically monitor blood sugar, cholesterol and triglycerides. * Use with caution in patient with history of asthma or diabetes
