Summary:
The paper deals with the study of the strength and disintegration time of tablets made of directly
compressible maltose Advantose 100. It studies the differences of the effects of two types of
lubricants, magnesium stearate and sodium stearylfumarate, on the above-mentioned properties, and
it also tests the mixtures of the substance with microcrystalline cellulose Vivapur 102 in a ratio of
1:1 and with ascorbic and acetylsalicylic acids. The compacts are obtained by using three
compression forces, excepting mixtures with active ingredients, where one compression force is
used. In the compression forces of 6 and 8 kN, no statistically significant difference was found in
the intervention of the lubricants into the strength of the compacts made of Advantose 100, only in
the compression force of 10 kN Pruv decreased the strength more than stearate. The mixture of
Advantose 100 and Vivapur 102 yielded the strongest tablets, an addition of Pruv to it decreased the
strength of compacts more than stearate. The periods of disintegration time of Advantose compacts
as well as those of the mixture of dry binders were longer with an addition of Pruv. The compacts
with acetylsalicylic acid possessed higher strength and a longer period of disintegration than those
with ascorbic acid. There was no statistically significant difference within the type of the lubricant
employed, both in the case of Advantose 100 and its mixture with Vivapur 102, between the values
of strength of the compacts with acetylsalicylic acid.
Key words:
Advantose 100 – Vivapur 102 – lubricants – tensile strength of tablets – time
