Grunenthal GmbH Release: Stronger! INTAC(TM) Formulation Technology Protects Intended Action of Extended Release Drugs

4/30/2012 11:53:10 AM

BEDMINSTER, N.J., April 30, 2012 /PRNewswire-USNewswire/ -- During this year's Drug and Delivery Formulations Summit (San Diego, CA) Grunenthal presents its new INTAC formulation technology designed to be crush-resistant and to protect intended action of extended release prescription opioid drugs.

Prescription opioids are at the center of a major public health crisis of misuse and abuse in the United States. 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.[1]. Prescription drugs are the second most-abused category of drugs after marijuana[2] and there are various routes of abuse of prescription drugs including crushing or dissolving tablets. In the case of controlled release tablets, such tampering typically destroys the intended drug action. 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 an effective means to address the issue.

At one of today's sessions, Dr. Eric Galia, Project Director International Technical Alliance Management of Grunenthal presents the company's INTAC technology. INTAC is a formulation platform that provides extraordinary hardness as a means of tamper deterrence while keeping the intended time-release characteristics of the product. The technology uses polyethylenoxide (PEO) of high molecular weight and a hot melt extrusion process that combines the two factors of heat and pressure. Tablets produced utilizing this process have an extraordinary mechanical strength. The resulting physicochemical properties not only impede pulverization of the tablets but also result in low extractability of active drug from the tablets in a wide range of solvents. These features combined create a significant hurdle to the non-oral misuse/abuse of controlled release formulations.

Grunenthal also participates in the show with a booth dedicated to the INTAC technology. Attendees are able to test the difference in crush resistance of INTAC tablets versus conventional prolonged release tablets themselves by actually trying to crush the tablets with a hammer.


INTAC, Grunenthal's tamper resistant formulation technology, is designed to deter various relevant routes of abuse/inadvertent misuse from tablet tampering by imposing a specific mechanical stability to the tablet. This mechanical stability is created by the combination of specific excipients together with a unique manufacturing process. Grunenthal's proprietary INTAC approach is established at commercial manufacturing scale and is featured in FDA-approved products which are marketed by U.S. partners. Grunenthal considers its patent protected INTAC to be the leading technology for abuse-deterrent and tamper-resistant opioid products. The INTAC technology is available for licensing to interested companies for various product opportunities.
