Patent number: 10898431Abstract: The present disclosure provides programmable osmotic-controlled oral compositions providing delayed release of a therapeutically acceptable amount of a drug. The programmable osmotic-controlled compositions of the disclosure provide a lag time that is independent of the presence or absence of food, type of food, pH, gastric emptying, gastric motility, and volume and viscosity of gastric fluid. The compositions of the disclosure can be programmed to provide a desired and precise lag time, and release drug, after the lag time, at a rhythm, e.g., that matches the human circadian rhythm of a condition's symptoms and/or of the individual being treated in the application of the therapy to optimize therapeutic outcome and minimize side effects.Type: GrantFiled: March 5, 2020Date of Patent: January 26, 2021Assignee: KASHIV BIOSCIENCES, LLCInventors: Siva Ram Kiran Vaka, Paras Jariwala, Jaydeep Vaghashiya, Atsawin Thongsukmak, Dipen Desai, Wantanee Phuapradit, Navnit H.

Patent number: 10898430Abstract: Self-regulating, osmotic, floating gastroretentive compositions that provide extended release, delayed release, and/or delayed extended release of active pharmaceutical agents, as well as, optionally, immediate release of the same or a different active pharmaceutical agent, are provided here. The gastroretentive compositions of the disclosure comprise a swellable, extended release, multilayer core comprising a push layer and a pull layer; a water-insoluble permeable elastic membrane surrounding the multilayer core; and an orifice (e.g., a laser-drilled orifice, a manually drilled orifice) on the pull-layer side of the dosage form. The gastric retention of the composition is controlled by rapid floating of the composition and expansion of the membrane.Type: GrantFiled: January 31, 2020Date of Patent: January 26, 2021Assignee: KASHIV BIOSCIENCES, LLCInventors: Navnit H. Shah, Wantanee Phuapradit, Dipen Desai, Jaydeep Vaghashiya, Kanji Meghpara

Patent number: 10881617Abstract: Extended release pyridostigmine dosage forms, suitable for maintaining stable plasma concentrations with reduced or minimized initial burst release/dose dumping of pyridostigmine, are provided. The dosage forms include matrix tablets, gastroretentive tablets, and pellets, the latter being suitable for dosing in capsules, tablets, and sachets, as well as for sprinkling on foodstuffs. The disclosure also provides methods for improving patient compliance by administering once-a-day extended release pyridostigmine bromide dosage forms that provide a superior controlled drug release.Type: GrantFiled: June 23, 2020Date of Patent: January 5, 2021Assignee: KASHIV BIOSCIENCES, LLCInventors: Siva Ram Kiran Vaka, Namdev B.
