  • Publication number: 20210228474
    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: 20210205207
    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: 11045420
    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.

  • Publication number: 20210145846
    Abstract: The present disclosure is directed to a pharmaceutical composition suitable for intramuscular (IM) administration, comprising fulvestrant, a pharmaceutically acceptable alcohol(s), a cosolvent(s), a lipophilic vehicle comprising a release-controlling oil, and, optionally, at least one surfactant and/or an antioxidant. The composition comprises fulvestrant at a concentration of at least 50 mg/ml, e.g., 100 mg/ml, wherein the composition exhibits excellent storage stability at long-term and accelerated storage conditions. The composition of the disclosure can deliver a 250-500 mg dose of fulvestrant as a single IM injection from a prefilled syringe, e.g., 500 mg/5 ml or 250 mg/2.5 ml in a prefilled syringe.

  • Patent number: 11007145
    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.

  • Publication number: 20210137827
    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.
