  • Patent number: 10894023
    Abstract: Disclosed herein is an oral dosage formulation suitable for treating a neurodegenerative disorder. The oral dosage formulation contains both sustained-release and immediate-release drugs. The sustained-release drug in the oral dosage formulation is memantine, and the immediate-release drug in the oral dosage formulation is donepezil and/or memantine, and the formulation is characterized in having a pH-independent dissolution profile of memantine at a pH range from about 1.0 to about 7.0.
    Type: Grant
    Filed: June 20, 2019
    Date of Patent: January 19, 2021
    Assignee: CENTER LABORATORIES, INC.

  • Publication number: 20080038355
    Abstract: Bioadhesive steroid nanoparticles are used to prepare a rapidly disintegrating solid oral dosage form of steroid. The bioadhesive steroid nanoparticles have a bioadhesive polymer surrounding the steroid nanoparticles and with an average diameter of less than 1000 nm. Hence, the solid oral dosage form, containing the bioadhesive steroid nanoparticles, a disintegrant and an effervescent agent, instantly disintegrates in the oral cavity and adheres on the periodontal pocket and oral mucosa to release steroid rapidly.
