Publication number: 20220233649Abstract: The disclosure relates to a dosage forms and combinations of dosage forms useful for effective oral administration of drugs which are otherwise unsuitable for oral administration, owing to acid- and/or protease-mediated degradation. The dosage forms include a self-microemulsifying drug delivery system (SMEDDS) with which the drug is combined and an antacid. When co-administered to a mammal, the dosage form(s) can prevent drug degradation by the strong acid and digestive enzymes normally present in the gastric environment, and can improve water-soluble drug absorption in gastrointestinal (GI) tract. The dosage forms can be used to effectively administer insulin by an oral route, for example, such as in the form of a powder that can be stored for long periods and reconstituted with water or another fluid shortly before administration.Type: ApplicationFiled: April 13, 2022Publication date: July 28, 2022Applicant: InnoPharmax, Inc.Inventors: Yu-Tsai YANG, Jong-Jing WANG, Pei-Jing HSU, Li-Chien CHANG, Wei-Hua HAO, Chang-Shan HSU

Patent number: 10835548Abstract: The disclosure relates to compositions and methods for treatment, such as inducing regression or inhibiting growth, of tumors in a patient such as a human. Use of gemcitabine, including in self-emulsifying orally administered dosage forms for these purposes is described. Gemcitabine is orally administered in a metronomic manner, which involves repeatedly administering a therapeutic amount of gemcitabine, being a fraction of the maximum tolerated dose, over an extended period of time, preferably on a non-interrupted schedule of weeks, months, or indefinitely.Type: GrantFiled: June 2, 2017Date of Patent: November 17, 2020Assignee: INNOPHARMAX, INC.Inventors: Wei-Hua Hao, Shu-Ping Hsueh, Chang-Shan Hsu

Publication number: 20190275006Abstract: The present invention provides an oral self micro-emulsifying pharmaceutical composition of a hydrophilic drug or a pharmaceutically acceptable salt thereof which, in addition to the hydrophilic drug, one or more solvents for solving the hydrophilic drug to form a drug-solvent solution and a surfactant system, further comprises one or more hydrophilic carrier which are compatible with said drug-solvent solution and the surfactant system. The oral self micro-emulsifying pharmaceutical composition of the invention exhibits comparative bioavailability to that of the hydrophilic drug through injection and is stable during storage. A method for preparing the oral self micro-emulsifying pharmaceutical composition is also provided.Type: ApplicationFiled: May 23, 2019Publication date: September 12, 2019Applicant: INNOPHARMAX, INC.Inventors: Chang-Shan HSU, Wei-Hua HAO, Jong-Jing WANG, Tsung-Hsin LIN

Patent number: 6094437Abstract: A system is provided for creating a tunneling service from the use of a traditional tunneling protocol, such as the layer two tunneling protocol (L2TP). In particular, the L2TP tunneling protocol, which is designed to go point-to-point between an L2TP Access Concentrator (LAC) and an L2TP Network Server (LNS), is abstracted so that L2TP becomes an access protocol to a tunneling service. A new L2TP tunnel merger and management (LTM) service is created which severs the tight configuration relationships between LAC and LNSs. Only a tight configuration between an LAC and its LTM edge device and between an LNS and its LTM edge device is required. An internal trunk protocol (INT protocol) carries needed information between LTM edge devices to establish ingress/egress L2TP access calls inside of separate L2TP access tunnels on opposite LTM edge devices.Type: GrantFiled: February 19, 1999Date of Patent: July 25, 2000Assignee: ASC - Advanced Switching CommunicationsInventors: James R.
