COMMACK, NY, March 11, 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 it has formalized multiple commercial Group Purchasing Organization (GPO) agreements for REZENOPY^TM (naloxone HCl) Nasal Spray 10 mg, providing access to more than 5000 healthcare institutions, including hospitals, clinics and nursing homes, representing potential penetration into roughly 60% of the U.S. institutional market while also establishing a broad footprint across first responders, EMS providers and rehabilitation centers.

“These GPO agreements represent a significant step forward in the commercial expansion of REZENOPY^™,” commented Narasimhan Mani, President and co-CEO of Scienture. “They meaningfully expand our institutional reach, providing access to more than 5000 healthcare facilities representing potential penetration into approximately 60% of the U.S. institutional market. With the U.S. naloxone market representing approximately $141 million in annual sales and 9.4 million prescription units, we believe REZENOPY^™, the highest-dose FDA-approved naloxone nasal spray, is well positioned to drive broader adoption and capture market share as we continue executing our commercialization strategy.”

Shankar Hariharan, Executive Chairman and co-CEO of Scienture, added, “Institutional procurement channels are a key driver of growth for emergency overdose treatments. Through these GPO partnerships, we are significantly expanding our presence across hospitals, EMS providers, and rehabilitation centers, creating a scalable pathway for the adoption of REZENOPY^™. We expect broader availability through these institutional channels to drive adoption and strengthen our growth trajectory as we scale our commercial operations.”

As previously disclosed, Scienture, LLC, a wholly-owned subsidiary of Scienture Holdings, Inc., entered into a definitive agreement with Summit Biosciences Inc. (a Kindeva subsidiary) in March 2025, for the exclusive U.S. commercialization rights to REZENOPY^™ (naloxone HCl) Nasal Spray 10 mg, which received FDA approval on April 19, 2024.

IMPORTANT SAFETY INFORMATION
REZENOPY^™ (naloxone hydrochloride) Nasal Spray 10 mg is an opioid antagonist indicated for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression in adult and pediatric patients. It is intended for immediate administration as emergency therapy in settings where opioids may be present and is not a substitute for emergency medical care.

Important Safety Information

• Contraindications: REZENOPY^™ nasal spray is contraindicated in patients known to be hypersensitive to naloxone hydrochloride or to any of the other ingredients.
• Warnings and Precautions:
  • Risk of Recurrent Respiratory and CNS Depression: Due to the duration of action of naloxone relative to the opioid, keep the patient under continued surveillance and administer additional doses as necessary while awaiting emergency medical assistance.
  • Risk of Limited Efficacy with Partial Agonists or Mixed Agonists/Antagonists: Reversal of respiratory depression caused by partial agonists or mixed agonists/antagonists, such as buprenorphine and pentazocine, may be incomplete. Larger or repeat doses may be required.

• Precipitation of Severe Opioid Withdrawal: Use in patients who are opioid-dependent may precipitate opioid withdrawal. In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated. Monitor for the development of opioid withdrawal.
• Risk of Cardiovascular Effects: Abrupt postoperative reversal of opioid depression may result in adverse cardiovascular effects. These events have primarily occurred in patients who had pre-existing cardiovascular disorders or received other drugs that may have similar adverse cardiovascular effects. Monitor these patients closely in an appropriate healthcare setting after use of naloxone hydrochloride.

• Adverse Reactions: The following adverse reactions were observed in a REZENOPY^™ nasal spray clinical study: upper abdominal pain, nasopharyngitis, and dysgeusia.
