  • Publication number: 20220040114
    Abstract: The present disclosure provides programmable osmotic-controlled oral compositions providing delayed extended release of a therapeutically acceptable amount of methylphenidate hydrochloride. 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, and volume 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 that matches the circadian rhythm of an individual being treated to optimize therapeutic outcome and minimize side effects.

  • Publication number: 20220031604
    Abstract: 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.

  • Patent number: 11229606
    Abstract: 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.

  • Publication number: 20210393512
    Abstract: 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.

  • Patent number: 11166906
    Abstract: The present disclosure provides programmable osmotic-controlled oral compositions providing delayed release of a therapeutically acceptable amount of a drug. In certain embodiments, 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, and volume of gastric fluid. The programmable osmotic-controlled oral compositions of the disclosure comprise a multilayer core comprising a drug for controlled release, wherein the core is coated with a semipermeable membrane comprising an orifice and, optionally, an immediate release coating, comprising a drug for immediate release, over the semipermeable membrane. The multilayered core comprises a pull layer containing the drug and a push layer.

  • Publication number: 20210236421
    Abstract: The present disclosure is directed to floating gastroretentive dosage forms with prolonged gastric residence time. The disclosure also provides rapidly expanding sustained release or combined immediate release and sustained release formulations comprising drugs that require targeted release in the proximal gastrointestinal tract for maximum therapeutic benefit. The rapidly expanding floating gastroretentive dosage forms comprise a permeable elastic membrane providing desired characteristics for drug release and mechanical strength to maintain tablet integrity.
