Patent number: 9066869Abstract: The invention is directed to oral modified/controlled release drug formulations which provide a rapid initial onset of effect and a prolonged duration of effect. Preferably, the peak concentration is lower than that provided by the reference standard for immediate release formulations of the drug, and the duration of effect falls rapidly at the end of the dosing interval.Type: GrantFiled: October 9, 2013Date of Patent: June 30, 2015Assignee: Purdue PharmaInventors: Thinnayam N. Krishnamurthy, Andrew Darke

Publication number: 20140194456Abstract: Abuse-resistant, controlled release opioid tablets are a combination containing an opioid antagonist such as naloxone at a level above that needed to suppress the euphoric effect of the opioid, if the combination were crushed to break the controlled release properties causing the opioid and opioid antagonist to be released as a immediate release product as a single dose. The controlled release nature of the table prevents the accumulation of orally effective amounts of opioid antagonist when taken normally. The opioid antagonist is contained in a controlled-release matrix and released, over time, with the opioid.Type: ApplicationFiled: March 11, 2014Publication date: July 10, 2014Applicant: Purdue PharmaInventors: Frank S. CARUSO, Huai-Hung KAO

Patent number: 7060293Abstract: An oral dosage form of morphine is formulated by powder-layering an homogeneous mixture of morphine sulfate and hydrous lactose impalpable onto inert beads to obtain a multiparticulate product. A plurality of the powder-layered beads may be administered either in immediate release form or in an extended release form by coating with a hydrophobic material. In addition, multi-particulate oral dosage forms containing therapeutically effective agents containing a plurality of pharmaceutically acceptable inert beads powder-layered with homogeneous mixture of a therapeutically effective agent and hydrous lactose impalpable are also disclosed. A method of preparing the dosage forms as well as a method preparing spheroids containing the homogeneous mixture of therapeutically effective agent and hydrous lactose impalpable are also disclosed.Type: GrantFiled: June 20, 2000Date of Patent: June 13, 2006Assignee: Purdue PharmaInventors: Benjamin Oshlack, Frank Pedi, Jr.
