Embodiment Construction

[0044] Tableting aids according to the invention were compared in a placebo (Placebo), 40% acetaminophen (Paracetamol) and enalapril (Enalapril) with a list of physical mixtures consisting of the individual components. The results are given in Tables 2, 3 and 4.

[0046]

[0047] ★ Tableting aids according to the invention are only compressed at different pressures.

[0048] ★★ All components except PRUV were mixed for 15 minutes. Lubricant was then added, mixed for an additional 3 minutes and compacted at various pressures.

Abstract

The invention relates to a process for producing a tabletting aid, which comprises the following process steps: - at least two of the following components are provided: a filler/binder; a lubricant; a flow regulator; a decomposition accelerator; the components provided are mixed with one another.

Description

technical field [0001] The present invention relates to a method, a preparation and a material according to the above title. Background technique [0002] Direct compression is a commonly used method for preparing tablets. The method consists of different mixing steps. Firstly the active substance and all auxiliary substances (mainly fillers, binders and disintegrants) are mixed with one another except the lubricant. This can be done in a separate mixing step, in which the filler, binder and disintegrant are added together to the effect substance. Instead of this it is also possible to carry out a plurality of successive mixing steps. The lubricant is then added to the mixture and mixed with it again. The result is a tabletting mixture. The tableting mixture is compressed on a tablet machine. [0003] Combined auxiliary materials (direct tableting auxiliaries) are present in pharmaceutical technology. These are combined tableting adjuvants which are prepared from indi...
