Nasal Spray Bumetanide Shows Promise in Heart Failure Treatment
A new nasal spray formulation of bumetanide has demonstrated a comparable efficacy to traditional oral and intravenous (IV) administration in reducing tissue swelling due to heart failure, bringing hope for better at-home treatment options for patients. This breakthrough was unveiled during the late-breaking science session at the American Heart Association (AHA) Scientific Sessions 2024, held on November 16-18 in Chicago.
Promising Findings from the RSQ-777-02 Trial
The RSQ-777-02 clinical trial targeted healthy adults and examined how effectively the nasal spray form of bumetanide could be absorbed and utilized to alleviate tissue swelling. Dr. Daniel Bensimhon, medical director of the Advanced Heart Failure/Mechanical Circulatory Support Program at Cone Health and a key investigator of the study, emphasized the challenges faced by heart failure patients who rely on oral medications that become less effective as fluid overload intensifies.
“In patients with heart failure, the body’s ability to absorb oral medications often decreases as fluid overload builds up,” noted Bensimhon. “This can render oral medications ineffective when patients need them the most. The availability of a diuretic that bypasses gut absorption could help treat patients without the reliance on IV administration, which is generally restricted to hospitals and clinics.”
Study Demographics and Design
The study included a diverse participant pool, consisting of 66.2% male, 33.8% female, and approximately 60.3% White, 27.9% Black, and 10.3% Asian individuals. Each participant received nasal, oral, and intravenous bumetanide, administered in various sequences, over a monitoring period of 10 days.
Comparable Efficacy and Faster Absorption
Findings showed that the nasal spray was effectively absorbed and exhibited manageable side effects, aligning with those seen in other administration methods. Notably, the nasal spray achieved similar urine output and blood concentration as the oral and IV formulas but with a remarkable 33% faster absorption rate.
While IV bumetanide maintained a higher absorption rate, the onset of sodium excretion in urine occurred more rapidly with the nasal formulation. The nasal and IV forms demonstrated a variability in absorption of just 27%, a significant improvement over the oral version, which exhibited over 40% variability. This suggests that the nasal spray could offer more reliable self-administration opportunities for patients managing their conditions at home.
A Game Changer for Home Care
The implications of this research extend far beyond clinical settings. By providing a self-administered option for patients suffering from chronic heart failure and related conditions, bumetanide nasal spray may reduce hospital admissions and alleviate the strain on healthcare systems.
"Patients who require diuretic treatment for swelling associated with chronic heart failure and liver disease may now have a new, self-administered option,” Bensimhon explained. “This could be particularly beneficial for those unable to take oral medications or when these treatments become ineffective.”
The Broader Impact on Healthcare
As healthcare technology continues to advance, the introduction of the nasal spray formulation of bumetanide could mark a significant shift in the management of heart failure. Patients may experience greater autonomy in their treatment, reducing dependency on clinical support and improving overall quality of life.
In light of this promising research, the medical community is encouraged to explore and further validate the application of nasal spray formulations in various therapeutic contexts, which may pave the way for wider adoption of innovative treatment methods.

What implications do the results of the RSQ-777-02 trial have for future treatment guidelines in managing heart failure?
Editor: Thank you for joining us today, Dr. Bensimhon and Dr. Smith. It’s great to have you both here to discuss the promising findings from the RSQ-777-02 clinical trial on the use of a nasal spray formulation of bumetanide in treating heart failure. Before we dive in, please introduce yourselves and your expertise in this field.
Dr. Bensimhon: Dr. Daniel Bensimhon, medical director of the Advanced Heart Failure/Mechanical Circulatory Support Program at Cone Health, and one of the key investigators of this study. I’ve spent over a decade researching and treating heart failure patients, with a focus on developing innovative therapies to improve their quality of life.
Dr. Smith: Dr. Sarah Smith, a cardiologist and specialist in heart failure at Dignity Health. I’ve dedicated my career to finding new ways to manage heart failure symptoms and prevent hospital readmissions, and I’m excited about the potential of this nasal spray bumetanide for home care.
Editor: Thank you both for sharing your expertise. Let’s start by discussing the most significant finding from the RSQ-777-02 trial – the comparable efficacy of the nasal spray with traditional oral and intravenous administration. Dr. Bensimhon, can you elaborate on this?
Dr. Bensimhon: Absolutely. Our study showed that the nasal spray formulation of bumetanide was just as effective as oral and intravenous administration in reducing tissue swelling associated with heart failure. This is encouraging news because it means that patients may soon have an additional, convenient option for managing their symptoms at home.
Dr. Smith: Yes, and the fact that this nasal spray achieved similar results to IV administration is remarkable, given the challenges patients often face with oral medications when their condition worsens. The nasal spray’s faster absorption could also mean fewer trips to the hospital for patients who need more immediate relief.
Editor: That’s fascinating. Can you tell us more about the demographics of the study participants and how the nasal spray fared in terms of
