  • Patent number: 9884029
    Abstract: A oral pharmaceutical composition for controlled release of an opioid from a pharmaceutical composition is described that comprises (i) an erodible matrix composition comprising a mixture of (a) a polymer or a mixture of polymers (b) an opioid, and optionally, (c) one or more pharmaceutically acceptable excipients; and (ii) a single, substantially insoluble in and impermeable coating having two openings exposing at least one surface of the matrix, and comprising one or more polymers. The composition exhibits controlled release of the opioid by erosion of the matrix and exhibits a zero order release profile wherein about 75% w/w of the opioid is released from the composition within 4-10 hours when tested in a dissolution test as described herein.

  • Patent number: 9795745
    Abstract: A syringe for mixing and ejecting an active pharmaceutical ingredient is disclosed. The syringe is designed in such a manner that it is ensured that substantially all of the mixed drug is ejected, and in such a manner that an active pharmaceutical ingredient can be lyophilized directly into the syringe. The syringe comprises a syringe body, a first plunger arranged movably inside the syringe body and a second plunger arranged movably inside the first plunger. In one aspect the second plunger comprises a first plunger part and a second plunger part, and the first and second plunger parts are adapted to cooperate to collapse the cavity of the first plunger. In a second aspect the cavity of the first plunger has a first diameter at a distal end and a second diameter at a proximal end, the first diameter being smaller than the second diameter.

  • Patent number: 9694080
    Abstract: A pharmaceutical composition for controlled release of an active substance, the composition being a matrix composition of: (a) a substantially water soluble or crystalline polymer, (b) an active substance, and optionally, (c) one or more pharmaceutically acceptable excipients having a water solubility of at least 1 mg/ml at ambient temperature. The matrix composition does not contain a water dispersible or water soluble surface active agent that has at least one domain, which is compatible with the polymer in the matrix composition, and which substantially eliminates water diffusion between the interface between the polymer crystals.

  • Publication number: 20160361269
    Abstract: A composition for controlled release of an opioid from a pharmaceutical composition, the method comprises controlling the release of at least one opioid into an aqueous medium by erosion of at least one surface of a pharmaceutical composition comprising I) a matrix composition comprising a) polymer or a mixture of polymers, b) an opioid and, optionally, c) one or more pharmaceutically acceptable excipients, and (i) a coating. The matrix composition has a conus-like shape so the surface area exposed to the aqueous medium increases at least during initial erosion of the matrix composition, and the dissolution of the opioid—when tested in a Dissolution Test as described herein with or without application of sinkers—results in a zero order release of at least 80% of the opioid contained in the composition. Such compositions are especially suitable for controlled release of an opioid to obtain a delayed pead concentration and a prolonged therapeutically effective plasma concentration upon oral administration.

  • Patent number: 9375428
    Abstract: Described are controlled release oral pharmaceutical composition comprising an erodible matrix composition comprising a polyethylene oxide, a therapeutically effective amount of an opioid or a pharmaceutically acceptable salt, complex, solvate or anhydrate thereof, or a mixture thereof and, optionally, one or more pharmaceutically acceptable excipients, and a coating on the matrix composition, wherein the coating has at least one opening exposing a surface of an end portion of the matrix composition, thereby allowing controlled release of the opioid by erosion of the matrix surface, wherein the composition exhibits zero order release of at least 80% of the opioid contained in the composition. The matrix may have a cylindrical shape having a long axis and a conus-shaped end portion having a largest diameter and a smallest diameter, such that the surface area exposed increases during erosion of the conus-shaped end portion.

  • Publication number: 20160074586
    Abstract: Disclosed herein is a ready-to-use injection device for single use and a container for such device. The container comprises at least one first closed chamber for containine an active substance and optionally a second closed chamber for containing a quid substance comprising an active substance or a solvent. The two chambers are separated by a separation wall which is impermeable and breakable upon exertion of an external force, resulting in enhanced mixing of the substances contained in the device with a minimal formation of air bubbles. The present injection device is safe and particularly well suited for enhanced mixing of pharmaceutically active compositions to be injected in patients and can be used for vaccination programs.
