Primary Aldosteronism (PA) is increasingly recognized as a hidden epidemic. In 2026, the Primary Aldosteronism Market is expanding rapidly as medical guidelines now mandate PA screening for any patient with resistant hypertension. Once thought to be rare, PA is now known to be the cause of up to 10% of all high blood pressure cases, representing a massive untapped patient population.In 2026, the primary aldosteronism Market is defined by Simplified Screening Tools. The traditional "Aldosterone-to-Renin Ratio" (ARR) test has been optimized with AI-driven interpretation models that account for age and medication interference, reducing false negatives. This has led to a 25% increase in diagnosis rates in primary care clinics over the last two years.
Treatment trends in 2026 are split between pharmacology and surgery. Mineralocorticoid Receptor Antagonists (MRAs) like eplerenone continue to lead the drug segment, but we are seeing the emergence of "Non-Steroidal MRAs" which offer fewer hormonal side effects. For those with unilateral adrenal tumors, Endocrine Robotic Surgery is the preferred path. The market is also seeing the rise of Adrenal Vein Sampling (AVS) Automation, where specialized catheters and real-time hormone assays are making the procedure safer and more accessible. As public health initiatives in North America and Europe push for "Precision Hypertension" management, the PA market is poised for sustained double-digit growth.
