Benefits of technology

[0018]The use of polymers (C) having the stated minimum breaking strength in the process according to the invention, preferably in quantities such that the dosage form also exhibits such a minimum breaking strength, means that pulverisation of the dosage form is considerably more difficult using conventional means, so considerably complicating or preventing the subsequent abuse.
[0021]The dosage form obtained according to the invention is thus suitable for preventing parenteral, nasal and / or oral abuse of pharmaceutical active ingredients with potential for abuse.

Problems solved by technology

Many pharmaceutical active ingredients, in addition to having excellent activity in their appropriate application, also have potential for abuse, i.e. they can be used by an abuser to bring about effects other than those intended.

[0153]Tramadol hydrochloride and polyethylene oxide powder and hydroxypropyl methylcellulose were mixed in a free-fall mixer. The magnesium stearate powder was then mixed in. The powder mixture was pressed into tablets on a Korsch EK0 eccentric press. The tabletting tool has a diameter of 10 mm and a radius of curvature of 8 mm. These tablets were further processed with the assistance of a laboratory heat sealer (Kopp laboratory sealer SPGE 20, Hot & Cold tack heat-sealed seam strength tester from Kopp). The heat sealing bars were replaced with two metal rails, into each of which had been milled a concavity having a diameter of 10 mm and a radius of 8 mm. The surface of the concavity is co...

Abstract

The present invention relates to a process for the production of abuse-proofed, thermoformed dosage forms containing, apart from one or more active ingredients with potential for abuse and optionally physiologically acceptable auxiliary substances, at least one synthetic or natural polymer with a breaking strength of at least 500 N.

Description

[0001]The present invention relates to a process for the production of solid pharmaceutical dosage forms with at least reduced potential for abuse, by[0002]a) shaping a formulation mixture containing at least one active ingredient with potential for abuse and at least one synthetic or natural polymer (C), which exhibits a breaking strength of at least 500 N, into formed articles by application of force,[0003]b) optionally singulating the formed articles and optionally in each case grading them by size and,[0004]c) after or during heating at least to the softening point of the polymer (C), exposing the formed articles to force until they have a breaking hardness of at least 500 N, optionally providing them with a cover and optionally mixing all the formed articles back together again.BACKGROUND OF INVENTION[0005]Many pharmaceutical active ingredients, in addition to having excellent activity in their appropriate application, also have potential for abuse, i.e. they can be used by an ...
