  • Publication number: 20180236078
    Abstract: The present disclosure provides compositions (e.g., extended release compositions) which exhibit a desirable pharmacokinetic profile of an active agent while providing reduced dissolution sample variability, e.g., in the form of reduced inter-capsule variability and/or a reduction in storage-time dependent change in mean release of the active agent from the composition. Related methods of making and administering the disclosed compositions and formulations are also provided.
