Study Notes
Classification
- Aldactone is classified as an aldosterone antagonist and potassium-sparing diuretic.
- It serves as an antihypertensive and antihypokalemic medication.
Action
- Inhibits sodium reabsorption by targeting aldosterone in the distal tubule.
- Promotes the excretion of sodium and water while retaining potassium.
- Produces diuresis and effectively lowers blood pressure.
Uses
- Manages edema associated with excessive aldosterone secretion.
- Indicated for hypertension, cirrhosis, hypokalemia, nephrotic syndrome, severe heart failure, and primary hyperaldosteronism.
Dosage
- For edema, dosages range from 25 to 200 mg per day, either as a single dose or in two divided doses.
- For hypertension, the recommended dose is between 25 to 50 mg per day in one or two doses.
- In heart failure, the dosage is typically 12.5 to 25 mg per day.
Side Effects
- Common side effects include hyperkalemia, dehydration, and hyponatremia.
- Other occasional effects may include nausea, vomiting, anorexia, abdominal cramps, diarrhea, headache, ataxia, drowsiness, confusion, and fever.
Contraindications
- Not suitable for individuals with acute renal insufficiency, anuria, or hyperkalemia.
- Caution is advised in cases of dehydration, hyponatremia, renal or hepatic impairment, and concurrent use of potassium supplements.
Nursing Implications
- Monitor patient weight and initiate strict intake and output measures.
- Evaluate hydration status and obtain baseline serum electrolytes, renal and hepatic function tests, and urinalysis.
- Assess for edema, vital signs, blood urea nitrogen/creatinine levels, mental confusion, thirst, cold or clammy skin, drowsiness, and dry mouth.
Patient Teaching
- Patients should expect an increase in urine volume and frequency.
- Advise reporting any irregular or slow pulse and avoiding high-potassium foods.
- Instruct to avoid alcohol and caution against tasks requiring alertness or motor skills until the body's response to the medication is established.
