US-based Amneal Pharmaceuticals has secured approval from the US Food and Drug Administration (FDA) for its 500mg/mL sodium oxybate oral solution.
The solution is prescribed for managing cataplexy and excessive daytime sleepiness (EDS) in individuals with narcolepsy, which is characterised by excessive daytime drowsiness, sudden sleep episodes, and cataplexy, a sudden loss of muscle tone triggered by emotions.

The FDA approved the company’s abbreviated new drug application (ANDA) for sodium oxybate, which references Jazz Pharmaceuticals’ Xyrem. According to Amneal, the approval expands its affordable medicines portfolio.
Before the FDA approval, the US drugmaker had been distributing a limited quantity of an authorised generic version of sodium oxybate oral solution.
Amneal retail affordable medicines senior vice-president Tony Rosa said: “This approval expands Amneal’s Affordable Medicines portfolio into a critical therapy area for patients living with narcolepsy, a rare neurological condition that affects approximately 150,000 individuals in the US.
“By offering sodium oxybate, Amneal is providing patients, providers, and payers with a more affordable alternative in a therapeutic category that has historically been limited to a single manufacturer.”
