Summary

The thermal decomposition of tablet components used in the granulation and tableting of pharmaceuticals, and of more than ten of the mixtures frequently encountered in solid dosage forms was studied by thermogravimetric and differential thermal analysis. From the decomposition of these mixtures, which were of varied composition, the influence of mixtures of various tablet components on the thermal decomposition of pharmaceuticals was evaluated. Use can be made of the results to establish the conditions to be fulfilled by a compound if thermal methods are to be used for qualitative and quantitative control of the declared composition of a solid formulation.

Zusammenfassung

Die thermische Zersetzung von Tablettenbestandteilen, die bei der Granulierung und Tablettierung von Arzneimitteln und in mehr als 10 solchen Gemischen oftmals festen Präparaten zugesetzt werden, wurden thermogravimetrisch und differential-thermisch analysiert. Aus der Zersetzung dieser verschieden zusammengesetzten Gemische wurde der Einfluß gemischter Tablettenbestandteile auf den thermischen Zerfall von Arzneimitteln ermittelt. Aus den Ergebnissen lassen sich die Bedingungen ableiten, die eine Verbindung erfüllen muß, damit sich thermische Methoden für die qualitative und quantitative Kontrolle der angegebenen Zusammensetzung eines festen Präparates eignen.
