  • Publication number: 20220296568
    Abstract: In various embodiments, provided herein are pamoate salts of monoamine Anti-Parkinsons disease agents including rotigotine, ropinirole, pramipexole, selegiline, rasagiline, and safinamide, pharmaceutical composition comprising the same, methods of preparing the same, and methods of using the same. For example, the pamoate salt herein can be characterized by a molar ratio of rotigotine, ropinirole, pramipexole, selegiline, rasagiline, or safinamide to pamoic acid of about 1:1 or about 2:1. The pamoate salt herein can also be crystalline including anhydrous, hydrate or solvate forms, or their polymorphs, or amorphous. The pamoate salts described herein can provide a long acting and/or extended release profile of the monoamine agents tor the treatment of Parkinsons disease (PD). Thus, also provided herein are methods of preparing a long acting and/or extended release injectable formulation of the monoamine agents using their respective pamoate salts.

  • Patent number: 10599613
    Abstract: Embodiments of the present disclosure relate to methods, systems, and computer program products for storage management. In one embodiment, a computer-implemented method is disclosed. According to the method, in response to receiving a request related to managing the at least one directory entry in the file system, at least one directory entry in a file system may be determined by a file system in a storage system, where each of the at least one directory entry is represented by digital numbers. An index for each of the at least one directory entry may be managed in the file system by the file system, where an index key for the index comprises the digital numbers themselves. In other embodiments, a computer-implemented system and a computer program product for managing the index are disclosed.
