U.S. losartan market totals approximately $241M annually with around 72M prescriptions, creating a significant opportunity for ARBLI^™ as the first FDA-approved ready-to-use oral suspension

COMMACK, NY, May 06, 2026 (GLOBE NEWSWIRE) -- SCIENTURE HOLDINGS, INC. (NASDAQ:SCNX), a holding company for existing and planned pharmaceutical operating companies focused on providing enhanced value to patients, physicians and caregivers through the development, commercialization, and distribution of novel specialty products that address unmet market needs, today announced that the United States Patent and Trademark Office (USPTO) has granted its third patent covering ARBLI^™ (losartan potassium) oral suspension, the first and only FDA-approved ready-to-use oral liquid formulation of losartan.

The newly issued patent, U.S. Patent No. 12,605,365, titled "Losartan Liquid Formulations and Methods of Use," was issued on April 21, 2026, and is expected to provide intellectual property protection through October 7, 2041.

"This third patent further strengthens our intellectual property portfolio around ARBLI^™ and reinforces the long-term value of this differentiated asset," commented Narasimhan Mani, President and co-CEO of Scienture. "ARBLI^™ is the first and only FDA-approved liquid losartan formulation available in the U.S. market. Its ready-to-dispense, flexible dosing formulation eliminates the need for compounding and provides a tailored treatment option for patients with oral adherence challenges, positioning ARBLI^™ as the clear market leader in this category."

ARBLI^™ is a proprietary oral suspension formulation of losartan potassium designed to improve patient access and compliance, particularly among pediatric, geriatric, and other patient populations with difficulty swallowing tablets, within the approximately $241 million U.S. losartan market, representing around 72 million prescriptions annually (IQVIA MAT Dec 2025). By eliminating the variability and inconvenience associated with pharmacy compounding, ARBLI^™ delivers a consistent, convenient, and scalable solution for healthcare providers.

Since its commercial launch, Scienture has made meaningful progress in advancing ARBLI^™ market adoption, supported by increasing physician awareness, expanding formulary access, and continued growth across key distribution channels. The Company believes ARBLI^™ is well-positioned to capture share in the large and established losartan market, particularly within patient segments requiring liquid dosing options.

"With three issued patents now supporting ARBLI^™, we believe we have established a strong foundation to drive sustained commercial growth," stated Shankar Hariharan, Executive Chairman and co-CEO of Scienture. "We remain focused on expanding access, increasing adoption, and executing on our commercialization strategy to fully realize ARBLI^™'s market potential."

About ARBLI^™

ARBLI^™ is a novel proprietary formulation of losartan, a widely prescribed angiotensin receptor blocker (ARB) for hypertension. It is the first and only liquid formulation of losartan on the market that does not require compounding and has reduced dosing volume and long-term shelf life at room temperature storage. ARBLI^™ is FDA-approved for the treatment of hypertension in patients greater than six years old, for reducing the risk of stroke in patients with hypertension and left ventricular hypertrophy, and for treating diabetic nephropathy in certain patients with type 2 diabetes. By offering a safe, effective, and convenient liquid alternative, ARBLI^™ provides a tailored solution for patients who require or prefer a liquid formulation. As an FDA-approved product, ARBLI^™ provides consistent quality and dosing accuracy, addressing the risks and inconsistencies often associated with extemporaneously compounded losartan prescriptions. ARBLI^™ has two issued patents from the USPTO, which are also listed in the FDA Orangebook.

ARBLI^™ is the first and only oral liquid formulation of losartan approved by the U.S. FDA. ARBLI^™ comes in a 165 mL bottle as a peppermint flavored suspension that does not require refrigeration, and has been approved for a shelf life of 24 months from the date of manufacture when stored at room temperature.

INDICATION

ARBLI^™ is an angiotensin II receptor blocker (ARB) indicated for:

Treatment of hypertension, to lower blood pressure in adults and children greater than 6 years old. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions.
Reduction of the risk of stroke in patients with hypertension and left ventricular hypertrophy.
Treatment of diabetic nephropathy with an elevated serum creatinine and proteinuria in patients with type 2 diabetes and a history of hypertension.

IMPORTANT SAFETY INFORMATION

Do not take ARBLI^™ when pregnant. When pregnancy is detected, discontinue ARBLI^™ as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. ARBLI^™ can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death.
Do not co-administer ARBLI^™ with aliskiren in patients with diabetes. Avoid use of aliskiren with ARBLI^™ in patients with renal impairment (GFR <60 mL/min).
Do not administer ARBLI^™ in patients with severe hepatic impairment. ARBLI^™ has not been studied in patients with severe hepatic impairment.
The most common adverse reactions are (incidence ≥2% and greater than placebo): dizziness, upper respiratory infection, nasal congestion, and back pain.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088. You may also contact Scienture at 1-833-754-4917.

About Hypertension

Hypertension (high blood pressure) is a cardiovascular condition, when the pressure in the blood vessels is too high (140/90 mmHg or higher). According to the CDC, hypertension, or high blood pressure, affects nearly half of adults in the United States, or 119.9 million people. Hypertension is defined as a systolic blood pressure of 140 mmHg or higher, and diastolic blood pressure of 90 mmHg or higher. Hypertension is a risk factor for stroke and heart disease, which are leading causes of death in the U.S. Factors that increase the risk of having high blood pressure include: older age, genetics, being overweight or obese, not being physically active, high-salt diet and drinking too much alcohol. Hypertension is clinically diagnosed if, when blood pressure is measured on two different days, the systolic blood pressure readings on both days is ≥140 mmHg and/or the diastolic blood pressure readings on both days is ≥ 90 mmHg.
