Patents by Inventor Alison Fleming

Alison Fleming has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10668060
    Abstract: Tamper-resistant pharmaceutical compositions have been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. The tamper-resistant compositions retard the release of drug, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is passes through the GI tract.

  • Patent number: 10525052
    Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opiods. In the preferred embodiment, the drug is modified to increase its lipophilicity by forming a salt between the drug and one or more fatty acids wherein the concentration of the one or more fatty acids is one to 15 times the molar amount of the active agent, preferably two to ten times the molar amount of the active agent. In one embodiment the modified drug is homogeneously dispersed within microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles or drug particles are coated with one or more coating layers, where at least one coating is water insoluble and preferably organic solvent insoluble.

  • Patent number: 8758813
    Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. In one embodiment, the drug is modified to increase its lipophilicity by forming a salt between the drug and one or more fatty acids wherein the concentration of the one or more fatty acids is one to 15 times the molar amount of the active agent. The abuse-deterrent composition prevents the immediate release of a substantial portion of drug, even if the physical integrity of the formulation is compromised and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is broken down or dissolved gradually within the GI tract by a combination of enzymatic degradation, surfactant action of bile acids, and mechanical erosion.

  • Publication number: 20070036843
    Abstract: An improved controlled release composition for non-parenteral administration of active agents and other therapeutics, particularly for oral or topical administration, has been developed. The composition is made by dispersing a complex formed of an active agent bound to an ion-exchange resin or to another form of resin or carrier, in a non-ionic non-aqueous (“NINA”) vehicle. The complexes are optionally coated with one or more layers of coating material to provide a controlled pattern of release of active agent from the carrier. Replacing the usual aqueous vehicle with a NINA vehicle, such as an oil or an ointment, allows the active agent-carrier complexes, with or without coatings, to be both orally and topically administered.

  • Publication number: 20050181050
    Abstract: A multiparticulate, modified release composition for oral administration has been developed. The formulation is made by complexing a drug with an ion-exchange resin in the form of small particles, typically less than 150 microns. The present invention provides novel extended release coated ion exchange particles comprising drug-resin complexes, produced by binding the salt form of the drug, that do not require impregnating agents to insure the integrity of the extended release coat. To prepare a modified release formulation, one or more of the following types of particles are formulated into a final dosage form: (a) Immediate release particles, (b) Enteric coated particles, (c) Extended release particles, (d) Enteric coated-extended release particles; and (e) Delayed release particles.

  • Publication number: 20040143213
    Abstract: The systems and methods described herein include, inter alia, drug delivery devices that can provide doses of medicaments over a defined region of skin. Such systems and methods described herein may employ a hollow perforator that can receive a volume of drug and an actuator that can drive the perforator through a stroke cycle that accelerates the perforator and the volume of drug distally and then decelerates the perforator so that the volume of fluid is ejected out of the perforator.
