Finerenone barred from SUS, limiting critical kidney protection for type 2 diabetes patients
Brazil’s Unified Health System (SUS) has formally decided against incorporating finerenone, a crucial medication designed to protect kidneys in patients with chronic kidney disease (CKD) stages 3 and 4, specifically those with albuminuria linked to type 2 diabetes. This resolution, announced by the Secretariat of Science, Technology and Innovation in Health, confirms that the drug will not be made available through the public healthcare network.
The decision means that thousands of Brazilians relying on public health services will continue to have access only to existing therapies. For individuals living with advanced type 2 diabetes, this represents a significant setback in accessing a treatment proven to slow kidney function decline.

Finerenone targets a critical pathway in the progression of diabetic kidney disease, offering a new approach to managing a condition that often leads to severe health complications. Its absence from the public formulary highlights ongoing challenges in expanding access to innovative medicines within the national healthcare system.
The Ministry of Health’s communication on the matter emphasized the profound impact of type 2 diabetes as a primary driver of renal failure globally, noting that the prevalence of end-stage renal disease is expected to rise in conjunction with diabetes rates. Chronic kidney disease also significantly escalates risks of cardiovascular mortality and morbidity, profoundly affecting patient quality of life.
Understanding Finerenone’s Role in Kidney Health
Finerenone, marketed in Brazil by Bayer S.A., operates by actively shielding kidneys already under severe metabolic strain. In advanced stages of type 2 diabetes, high blood sugar levels overstimulate Mineralocorticoid Receptors (MRs). This overstimulation triggers inflammation within the kidney’s delicate blood vessels, leading to the leakage of protein into the urine, a condition known as albuminuria.
The medication directly intervenes to block this inflammatory process. By reducing protein leakage, finerenone helps prevent the progressive scarring and eventual loss of kidney function. This protective action is critical in potentially delaying or even avoiding the need for dialysis, a life-sustaining but invasive treatment that profoundly alters a patient’s life.

The Growing Burden of Chronic Kidney Disease
Type 2 diabetes stands as the leading cause of kidney failure in many developed nations, and its global prevalence continues to surge. This widespread increase directly contributes to a projected rise in end-stage renal disease cases worldwide, placing immense pressure on healthcare systems.
In Brazil, the statistics underscore a pressing public health challenge: more than 170,000 individuals currently undergo dialysis due to chronic kidney disease. This number not only reflects the advanced stage of their condition but also the significant financial and logistical strain on families and public health resources.
Implications for Public Healthcare Access
The non-incorporation of finerenone leaves patients within the SUS framework without a therapeutic option that has demonstrated clear benefits in clinical trials. These individuals, often from economically vulnerable backgrounds, face limitations in accessing treatments available in the private sector.

Currently, patients are managed with conventional approaches that include blood sugar control, blood pressure management, and other medications to mitigate kidney damage. While these therapies are essential, finerenone offered an additional, targeted mechanism to enhance kidney protection beyond existing options.
The decision underscores a broader debate within public health about balancing cost-effectiveness with the imperative to provide the most advanced care, particularly for chronic, progressive diseases like diabetic kidney disease.

The Mechanism Behind Kidney Protection
The progression of kidney damage in type 2 diabetes is largely driven by persistent inflammation and fibrosis, instigated by sustained hyperglycemia. The overactivation of mineralocorticoid receptors is a key contributor to this destructive cycle, leading to structural and functional changes in the kidneys.
Finerenone’s ability to selectively block these receptors helps to disrupt the inflammatory cascade, thereby preserving the integrity of renal tissues. This targeted approach offers a distinct advantage in preventing the irreversible scarring that ultimately leads to complete kidney failure.
A Look at Existing Treatments and Future Challenges
Current management strategies for diabetic kidney disease in the SUS primarily focus on managing the underlying diabetes and associated cardiovascular risks. These include medications like ACE inhibitors or ARBs, which are effective in reducing blood pressure and, to some extent, albuminuria.
However, even with optimized conventional therapy, many patients with type 2 diabetes still experience progressive kidney damage. This persistent risk highlights the unmet need for additional therapeutic interventions that can further protect renal function and improve long-term outcomes for this vulnerable population.

The absence of finerenone from the public health system means that a potentially life-changing treatment option, one that offers a novel pathway for kidney protection, remains out of reach for a significant portion of the Brazilian population. This situation prompts continued discussion among medical professionals, patient advocacy groups, and policymakers.
Patient Advocacy and Medical Needs
Patient organizations and medical societies often advocate for the inclusion of new, effective treatments into public health systems, citing the proven benefits and potential for improved quality of life and reduced morbidity. The decision regarding finerenone will likely fuel further discussions on pharmaceutical access and health equity.
Addressing the growing public health crisis of chronic kidney disease linked to type 2 diabetes requires a comprehensive strategy that includes prevention, early diagnosis, and access to the most effective treatments available. This decision, in the view of many, represents a missed opportunity for enhanced patient care.
