INTAC® - Grunenthal Group Presents Data Demonstrating the Strength of Its Tamper Resistant Technology at the American Association of Pharmaceutical Science Annual Meeting and Exposition

10/18/2012 9:45:54 AM

BEDMINSTER, N.J. and AACHEN, Germany, Oct. 16, 2012 /PRNewswire/ -- Grunenthal, a global family-owned pharmaceutical company specializing in pain management, today announced that data will be presented in two posters at this year's annual meeting of the American Association of Pharmaceutical Science taking place in Chicago, IL from October 14 18, 2012.

Grunenthal experts will discuss and present details of their innovative INTAC® technology in the following two posters:

  • "INTAC®: A Novel Formulation Platform to Protect Intended Drug Action" (abstract #1106); Authors: L. Barnscheid*, K. Wening*, E. Galia*, J. Bartholomaus+ (Grunenthal GmbH / +Pharmakreativ)

The study showed that tablets using the INTAC® technology are characterized by outstanding resistance against pulverization by exhibiting a breaking strength of more than 500 N. Additionally, the company's extended release formulation does not require aversive additives, protecting the intended drug action and raising hurdles against misuse and abuse of opioid products.

  • "Development of a Standardized Hammer Test for the Assessment of INTAC® Tablets" (abstract #1110); Authors: L. Barnscheid*, K. Wening*, B. Hoher+, R. Dahlmann+ (*Grunenthal GmbH / +Institute of Plastics Processing (IKV) at RWTH Aachen University)

In order to assess the INTAC® technology's ability to prevent pulverization of a tablet, Grunenthal developed a mechanical test that was representative, reproducible and reliable to evaluate this measure. The study found that a representative test to measure pulverization could be defined, and an apparatus was constructed to allow for reproducible and reliable testing.

The posters will be presented on Tuesday, October 16th from 9:30 AM -12:30 PM CDT in Hall F in McCormick Place. At booth #2648, the Grunenthal team will also provide information on INTAC®. Booth visitors are invited to personally experience the outstanding crush resistant properties of INTAC® tablets in attempting to smash the tablets with a hammer.

Prescription opioids are at the center of a major public health crisis of misuse and abuse in the United States1. Today, prescription drug abuse is the fastest growing drug problem in the U.S., and drug overdose death rates have risen steadily in the U.S. Technological approaches that intend to prohibit or reduce the ability to abuse specific time-release drugs by tampering with the formulation through crushing are therefore considered an effective means to address the issue2. Opioid manufacturers are looking to address ways in which they can adapt formulations of drugs to offer tamper resistance.

About INTAC® Technology

Tablets produced using INTAC® technology are designed to resist crushing even by heavy hammer blows, foiling the key step in most forms of opioid abuse. In addition to their high breaking strength, tablets produced by the INTAC® process form a gel in aqueous solutions that cannot be readily injected, and they resist extraction of active drug by a wide range of solvents. The mechanical stability is created by the combination of specific excipients together with a unique manufacturing process. INTAC® is the leading tamper resistance technology now in use, with two FDA-approved products already available in the United States. INTAC® manufacturing is established on a commercial scale in the U.S. and Europe. The technology is available for licensing to interested companies for various opportunities. Companies licensing INTAC® technology for their products are following a proven approach with a track record of regulatory approval. For more information about INTAC® please visit
