Overview

The optimal therapy for primary hyperladosteronism depends on the etiology of hyperaldosteronism.

Medical Therapy

Indications

Medical therapy is indicated for:

  • Bilateral adrenal hyperplasia
  • All ambiguous causes of primary hyperaldosteronism.

The following agents may be used to medical management of primary hyperaldosteronism:

Drug Class Agents Mechanism of action Dosage Side effects
Mineralocorticoid receptor antagonists Spironolactone
  • Competitive binding of receptors at the aldosterone-dependent sodium-potassium exchange site in the distal convoluted renal tubule
  • 12.5 – 25 mg BID
  • Max of 400 mg OD
  • Digestive: Gastric bleeding, ulceration, gastritis, diarrhea and cramping, nausea, vomiting.
  • Endocrine: Gynecomastia, irregular menses or amenorrhea, postmenopausal bleeding, carcinoma of the breast
  • Hematologic: Agranulocytosis.
  • Hypersensitivity: Fever, urticaria, maculopapular or erythematous cutaneous eruptions, anaphylactic reactions, vasculitis.
  • Hyperkalemia
  • Nervous system /psychiatric: Mental confusion, ataxia, headache, drowsiness, lethargy.
  • Liver / biliary: cholestatic/hepatocellular toxicity
  • Renal: Renal dysfunction (including renal failure).[1]
Potassium canrenoate
  • Aldosterone antagonist
  • Parentral administration
  • 200 mg OD
  • Max of 800 mg OD
  • Hoarseness
  • Deepening of voice
  • Hyperkalemia
  • Nausea
  • Vomiting
Eplerenone
  • Selective aldosterone antagonist
 50 mg OD[2]
  • Hyperkalaemia
  • Hypotension
  • Dizziness
  • Altered renal function
  • Increased creatinine concentration
Potassium-sparing diuretics
  • Amiloride
  • Triamterene
  • Acts on distal renal tubule where it selectively blocks sodium transport, leading to inhibition of sodium-potassium exchange[3]
  • Initial dose: 5 mg OD
  • Maintenance dose: 5-10 mg OD[4]
    • Nausea,
    • Vomiting
    • stomach or abdominal pain
    • Anorexia
    • Bloating,
    • Diarrhea
    • Headache
    • Dizziness
    • Skin rash
    • Weakness
    • Fatigue
    • Constipation
    • Muscle cramps
    • Cough
    • Dyspnea
Calcium channel blockers
  • Amlodipine
  • Nifedipine
  • Prevent calcium from entering cells of the blood vessel walls, resulting in lower blood pressure[5]
  • 5 mg OD
  • Max of 10 mg OD[6]
  • Edema
  • Flushing
  • Diziness
  • Palpitations
  • Headache
  • Abdominal pain
  • Somnolence[7]
  • May mask diagnosis of Conn's syndrome[8]
ACE inhibitors
  • Lisinopril
  • Captopril
  • Inhibits angiotensin-converting enzyme (ACE) thereby decreasing levels of angiotensin II and blocking the release of aldosterone.[9]
  • Cough
  • Increased creatinine concentration
  • Angioedema
  • Hyperkalemia
  • Renal impairment if given in bilateral renal artery stenosis
  • Agranulocytosis[11]
Angiotensin receptor blockers
  • Losartan
  • Candesartan
  • Valsartan
  • Angiotensin II inhibition by interacting selectively with the receptor site and blocking it[12] [13]
  • 50 mg OD (Losartan)[14]
  • 16 mg OD (Candesartan)[15]
  • 80mg-160mg OD (Valsartan)[16]
  • Diziness
  • Fatigue
  • Diarrhea
  • Dyspepsia
  • Abdominal pain
  • Arthralgia
  • Sinusitis[17]
Dexamethasone therapy(For familial hyperaldosteronism type I)
  • 0.5mg-0.75mg OD
