Benefits of technology

[0109]The term “bed of free flowing tablets” is defined for the purposes of the present invention as referring to a batch of tablets that are kept in motion with respect to each other as e.g. in a coating pan set at a suitable rotation speed or in a fluidized bed of tablets. The bed of free flowing tablets preferably reduces or prevents the sticking of tablets to one another.

Problems solved by technology

Pharmaceutical products are sometimes the subject of abuse.
Controlled release opioid agonist dosage forms which can liberate a portion of the opioid upon exposure to ethanol, can also result in a patient receiving the dose more rapidly than intended if a patient disregards instructions for use and concomitantly uses alcohol with the dosage form.

example 1

[0393]In Example 1 a 200 mg tablet including 10 mg of oxycodone HCl was prepared using high molecular weight polyethylene oxide in combination with hydroxypropyl cellulose.

Composition:

Ingredientmg / unit%Oxycodone HCl105Polyethylene Oxide16080(MW: approximately4,000,000;Polyox ™ WSR-301)Hydroxypropyl3015Cellulose(Klucel ™ HXF)Total200100

Process of Manufacture:

[0395]The processing steps to manufacture tablets were as follows:[0396]1. Oxycodone HCl, Polyethylene Oxide and hydroxypropyl cellulose was dry mixed in a low / high shear Black & Decker Handy Chopper dual blade mixer with a 1.5 cup capacity.[0397]2. Step 1 blend was compressed to target weight on a single station tablet Manesty Type F 3 press[0398]3. Step 2 tablets were spread onto a tray and placed in a Hotpack model 435304 oven at 70° C. for approximately 14.5 hours to cure the tablets.

Abstract

The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.

Description

[0001]This application claims priority from U.S. Provisional Application Ser. No. 60 / 840,244, filed Aug. 25, 2006, the disclosure of which is hereby incorporated by reference.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.BACKGROUND OF THE INVENTION[0003]Pharmaceutical products are sometimes the subject of abuse. For example, a particular dose of opioid agonist may be more potent when administered parenterally as compared to the same dose administered orally. Some formulations can be tampered with to provide the opioid agonist contained therein for illicit use. Controlled release opioid agonist formulations are sometimes crushed, or subject to extraction with solvents (e.g., ethanol) by drug abusers to provide the opioid contained therein for immediate release upon oral or parenteral adm...
