Benefits of technology

The invention is about using polymers in a process to make a drug that is difficult to crush or snort, which helps prevent abuse. The polymers are added in a specific amount and make the drug harder to break down. This makes it harder for people to abuse the drug.

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.

[0156]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 ...

[0160]As stated in Example 1, tablets with a diameter of 10 mm and a radius of curvature of 8 mm were produced.

[0161]The tablets were also further processed as in Example 1, except that the sealing bars were heated to 100° C.

[0162]The breaking strength of the tablets is determined using the above-described method. No breakage occurred when a force of 500 N was applied. The tablets could not be comminuted using a hammer, nor with the assistance of a pestle and mortar.
