  • Publication number: 20170050007
    Abstract: Apparatus and methods for inserting a medicament into a body cavity are described. The apparatus comprises an elongate tube with a plunger rod therein. The plunger rod has at least one projection which cooperatively interacts or engages with at least one discontinuity on the inside of the elongate tube so that proximal movement of the plunger rod with respect to the elongate tube expels the medicament into the body cavity.

  • Publication number: 20160346274
    Abstract: Disclosed are solid oral pharmaceutical compositions that that are intended to provide protection against overdose and tampering, as well as abuse deterrence. The compositions contain a plurality of granules or multi-particulates. A first population of multi particulates contains an API or drug susceptible to abuse, a polymer matrix, and an outer coating that contains a cationic pH dependent polymer. These multi particulates also contain a plasticizer and a surfactant. A second population of multi particulates contains a viscosity building polymer and an alkaline buffering agent. Compositions may further include a disintegrant, and/or additional viscosity building polymers and/or alkaline buffering agents and/or ion exchange polymers. Also disclosed are the methods of making and using the compositions.

  • Publication number: 20160317530
    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.

  • Publication number: 20120213827
    Abstract: A process for controlling the crystallization of certain hydrophobic active pharmaceutical ingredients (APIs) from a supercooled liquid state by hot-melt extrusion processing is described. Also described is a pharmaceutical composition comprising a solid crystalline dispersion of a cholesterol ester transfer protein inhibitor in a hydrophilic excipient matrix. In the process of the present invention, the API is fed to an extrusion system in a crystalline state contemporaneously with carrier excipients where it is first converted to a non-crystalline state by the application of heat and then subsequently recrystallized in-situ by the removal of heat and application of shear. Recrystallization of the API is controlled by carrier formulation design and the hot-melt extrusion process parameters; i.e. barrel temperature profile, feed rate, etc.
