Last updated: February 19, 2026

This report details current and projected bulk active pharmaceutical ingredient (API) sources for XYREM (sodium oxybate). The analysis focuses on identifying key manufacturers, production capacities, regulatory approvals, and potential supply chain risks. Understanding these factors is critical for pharmaceutical companies involved in the manufacturing, procurement, or investment related to XYREM.

What is the Regulatory Status of XYREM API?

XYREM is approved by the U.S. Food and Drug Administration (FDA) and is indicated for the treatment of cataplexy and excessive daytime sleepiness (EDS) in patients 7 years of age and older with narcolepsy. The active ingredient, sodium oxybate, is a Schedule III controlled substance in the United States due to its potential for abuse and diversion. This designation subjects its manufacturing, distribution, and prescribing to stringent regulations enforced by the Drug Enforcement Administration (DEA) in addition to the FDA.

FDA Approvals

The FDA approval for XYREM is held by Jazz Pharmaceuticals. The approved API is manufactured under strict Current Good Manufacturing Practice (cGMP) standards. Any company seeking to supply sodium oxybate API for XYREM must adhere to these cGMP requirements and undergo rigorous FDA inspections and audits.

DEA Controlled Substance Classification

As a Schedule III controlled substance, sodium oxybate API is subject to DEA quota systems that limit the total amount of the substance that may be manufactured or imported into the United States in a given year. Manufacturers of sodium oxybate API must apply for and receive DEA registration and annual manufacturing quotas. This classification significantly impacts the availability and production planning for the API.

International Regulatory Approvals

XYREM is also approved in other jurisdictions, including Canada and the European Union, for similar indications. These approvals necessitate API sourcing that complies with the respective regulatory bodies, such as Health Canada and the European Medicines Agency (EMA). Compliance with diverse international regulatory landscapes is a key consideration for global API suppliers.
