About this trial

This is a prospective randomized controlled trial where quality of life and the effectiveness of treatment will be evaluated in 80 patients with confirmed unilateral primary aldosteronism ,randomly assigned to be either treated surgically with unilateral adrenalectomy or to receive medical treatment with eplerenone.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with confirmed unilateral PA

Age 18-70 years

Candidate for surgical treatment

No contraindications for minimally invasive surgery or treatment with MRA

Disqualifiers

Unwilling or unable to undergo surgery

Unwilling to accept medical treatment for 12 months and not receiving standard treatment (surgery)

Impaired renal function with eGFR <45 ml/min/1,73m2

P-cortisol >138 nmol/L following 1-mg overnight dexamethasone suppression test.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Unilateral adrenalectomy

    Procedure/Surgery

    Minimally invasive surgery is performed via the lateral transperitoneal approach or the posterior retroperitoneal approach, with or without robotic assistance, according to the surgeon's preference.

  • Medical treatment (eplerenone)

    Drug

    The initial dose of eplerenone is 25 mg twice daily. The dose will be increased by 50 mg every fourth week until systolic blood pressure of 140 mmHg and diastolic blood pressure of 90 mmHg or lower has been reached and biochemical control (plasma renin above the middle of the reference range, i.e \> \~20 mIU/L) is attained and/or hyperkalemia develops. The maximal dose of eplerenone is 300 mg twice daily.

Treatment groups

80 Participants
are divided into 2 treatment groups
Group A: Surgically Treated Primary AldosteronismActive comparator 1 intervention
Group B: Medically Treated Unilateral Primary AldosteronismActive comparator 1 intervention
