摘要:
Pharmaceutical compositions in the form of tablets are disclosed including water-soluble active ingredients such as levetiracetam and a polymer component which primarily includes water-insoluble polymers comprising between 60% and 100% of the polymer component in the tablet core, preferably the entire polymer component in the tablet core. The pharmaceutical compositions can also include an extended-release coating including both water-soluble and water-insoluble polymers.

摘要:
Stabilized sustained release pharmaceutical preparations containing a drug which is sensitive to a low pH environment, such as pravastatin are disclosed in which pravastatin degradation is prevented with a buffering agent. The basic excipient enhances storage stability.
摘要:
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.
