  • Publication number: 20190125678
    Abstract: Oral dosage forms that contain hydrogel-forming polymers useful for achieving sustained release of API. The formulations disclosed herein may include a hydrogel-forming polymer and a water-insoluble hydrophilic polymer, which acts as a wicking agent to draw water into the formulation. Through that wicking, water combines with the hydrogel-forming polymer to form a hydrogel, thus permitting efficient and sustained release of the API from the hydrogel-forming polymer which may act as a matrix for the API. The formulations disclosed herein are particularly useful for sustained-release of a relatively water-insoluble API, such as tamsulosin, budesonide, and pharmaceutically acceptable salts thereof.

  • Patent number: 9138430
    Abstract: The present invention provides a delayed and/or controlled release formulation of paroxetine or a pharmaceutically acceptable salt thereof that is formulated to release a substantial portion of the active ingredient (e.g., paroxetine) in the large intestine of an individual in need thereof. In one embodiment, the present invention provides a controlled release paroxetine composition comprising paroxetine or a pharmaceutically acceptable salt thereof, in a controlled release swallow pharmaceutical formulation, that upon administration, releases the paroxetine substantially in the large intestine. For example, the controlled release paroxetine formulation may be formulated to release greater than about 50% of the paroxetine in the large intestine.
