Study Notes
Spironolactone Overview
- Therapeutic class primarily used for hypertension (HTN) and edema.
- Falls under the pharmacologic class of Potassium-Sparing Diuretics.
Common Drugs in Class
- Other potassium-sparing diuretics include Amiloride (Midamor), Eplerenone (Inspra), and Triamterene (Dyrenium).
Pregnancy Category
- Classified as Pregnancy Category D, indicating positive evidence of risk to the fetus.
Clinical Uses
- Effective for managing HTN, edema, and in conjunction with antihypertensives.
- Treats hyperkalemia, congestive heart failure (CHF), and primary aldosteronism.
Mechanism of Action
- Inhibits aldosterone to increase sodium and water excretion while retaining potassium at the late distal tubule.
Administration Route
- Administered orally (PO).
Pharmacokinetics
- Peak effect is observed within 2-3 days after administration.
Contraindications
- Contraindicated in pregnancy, lactation, renal impairment, cardiovascular disease (CVD), diabetes mellitus (DM), hyperkalemia, hyperlipidemia, anuria, and metabolic acidosis.
Adverse Effects
- May cause minor hyperkalemia (weakness, dyspnea, dysrhythmia), fatigue, headache, significant hyperkalemia, electrolyte depletion, dehydration, and possible metabolic acidosis.
- Other notable adverse effects include hyperglycemia, coma, blood dyscrasias, impotence, menstrual cycle irregularities, and agranulocytosis.
Drug Interactions
- Increased risk of acidosis when combined with ammonium chloride.
- Risks for hyperkalemia increase with potassium supplements and ACE inhibitors/ARBs.
- Additive hypotensive effects when used with other antihypertensives.
- Potential reduced effectiveness of anticoagulants and antidiabetics.
- Cholesyramine and colestipol may decrease absorption.
- NSAIDs can lead to increased renal toxicity and reduced diuretic effects.
- Corticosteroids and Amphotericin B may enhance potassium loss.
- Increased risk of toxicity with digoxin and potential lithium toxicity.
Overdose Treatment
- Treat overdose by infusing fluids to manage electrolyte depletion, dehydration, and hypotension.
Nursing Implications
- Effects may take 12-48 hours to manifest, and it is advisable to administer with food to enhance absorption.
- Avoid potassium supplements and high potassium foods.
- Typically used in combination with other diuretics.
- Monitor for signs of metabolic acidosis, hydration status, and electrolytes.
- Early administration is recommended to prevent nocturia (before 1400).
- Monitor weight loss and assess urine output.
