Modified-release Gamma-Hydroxybutyrate – Cellets formulation

The patent application titled “Modified Release Gamma-Hydroxybutyrate (GHB) Formulations Having Improved Pharmacokinetics” (US20240148685) focuses on improving the delivery of GHB, a substance used for treating sleep disorders like narcolepsy, through modified-release formulations. The goal is to optimize GHB’s absorption, enhancing patient convenience and compliance by reducing the need for multiple nightly doses.

The key innovation in the patent is the use of CELLETS® , microcrystalline spheres often employed as a neutral core for drug layering. In this application, CELLETS® act as carriers for the active ingredient, allowing precise control over the release profile of GHB. These small spherical particles, made from microcrystalline cellulose, offer uniform size and high mechanical strength, ensuring consistent drug loading and a controlled release rate.

In this patent, the CELLETS® are coated with various layers of GHB and release-modifying agents, enabling a predictable and sustained release of the active substance. This modified release profile allows GHB to be administered in a once-nightly dose rather than requiring the patient to wake up for a second dose, which was a limitation with previous immediate-release formulations. This extended-release mechanism helps maintain stable plasma concentrations of GHB over an 8-hour period, improving both the efficacy of the treatment and patient compliance.

The innovation emphasizes addressing the shortcomings of existing GHB formulations by ensuring a better pharmacokinetic profile—particularly regarding absorption, bioavailability, and minimizing drug levels in the bloodstream after the therapeutic effect has been achieved. In this specific patent, the following MCC Sphere types are recommended: CELLETS® 90, CELLETS® 100, CELLETS® 127.
