  • Patent number: 10898431
    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: 10898430
    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: 10881617
    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.

  • Patent number: 10869839
    Abstract: The present disclosure provides extended release trihexyphenidyl compositions suitable for once- or twice-daily administration. The compositions comprise a core comprising organic acid that is coated with at least one drug layer comprising trihexyphenidyl hydrochloride, and a functional coat over the drug-layered core. The extended release compositions of the disclosure provide reduced Cmax, a Cmin:Cmax ratio of ?0.4, and extended release, while maintaining therapeutically effective concentration, of trihexyphenidyl for at least about 16 hours. The compositions of the disclosure improve solubility of trihexyphenidyl hydrochloride, at a pH of greater than or equal to 5, to maintain its minimum effective concentration at such pH.

  • Patent number: 10857098
    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.

  • Patent number: 10744131
    Abstract: Disclosed are abuse resistant oral pharmaceutical compositions that reduce the likelihood of improper administration of drugs that are susceptible to abuse. The oral pharmaceutical formulations contain abuse deterrent agents that cause discomfort to the user when administered in an improper manner and make the extraction of an active ingredient more difficult. Methods of making and using the compositions are also disclosed.

The gastric retention of the composition is controlled by rapid floating of the composition and expansion of the membrane. The rapid swelling of the composition to a size greater than the size of the pyloric sphincter is due to the presence of an osmogen.
