Omyanutra® 300 DC – Direct compressible, porous excipient for nutraceuticals
Producing nutraceuticals in solid dosage form is complex and faces many challenges. In production, manufacturers choose either wet or dry granulation, or, which is becoming more popular, direct compression. Direct compression (DC) results in the shortest, most efficient and least complex way to…

Omyanutra® 300 Flash – The all-in-one solution for ODTs and FDTs
The world of nutraceutical tablet formulation is complex and many critical values have to be considered during development - like dissolution properties, shelf-life stability, or exposure to environmental challenges (oxygen, light, humidity and high or low temperatures).
The high number of…

Calcium Carbonate as Functional Filler in Polyamide 12 – Manipulation of the Thermal and…
Adjusting the thermal response properties of a polymeric compound can significantly improve the usability in a selective laser-sintering process. As previously shown, combining a precise amount of coarse and narrow size distribution fine calcium carbonate fillers results in a potential optimization…

High Acceptability of an Orally Dispersible Tablet Formulation by Children
There is a high unmet medical need for child-appropriate oral dosage forms. The acceptability of a novel placebo orally dispersible tablet formulation (pODT) was therefore evaluated. Monolithic tablets contain an inorganic calcium carbonate/calcium phosphate carrier material as the main excipient.…

Study of drug particle distributions within mini-tablets using synchrotron X-ray microtomography and…
Uniform drug distribution within fast disintegrating tablets is a key quality measure to ensure a reliable, steady, and targeted release of the contained active pharmaceutical ingredients. In this work, the drug particle distribution in mini-tablets was studied with synchrotron phase contrast X-ray…

Stabilization of amorphous drugs – are crystalline inorganic excipients a way forward?
Physical instability arguably is the major challenge in using neat amorphous active pharmaceutical ingredients in everyday tablets and capsules. The conversion of an amorphous form to the crystalline state either during storage or drug dissolution constitutes physical instability of amorphous drugs,…

Use of calcium carbonate as an excipient for release of poorly water soluble drugs: The case of…
Carbamazepine (CBZ) is a poorly water soluble drug owing to the Biopharmaceutic Classification System (BCS) class II. It is characterized by a variable bioavailability and by the presence of different polymorphs. In this paper the effects of CaCO3 on the physicochemical properties of CBZ and its…

Functionalised calcium carbonate as a coformer to stabilize amorphous drugs by mechanochemical…
The aim of this study was to investigate the amorphization, physical stability and drug release of a model drug, carvedilol (CAR), when loaded onto functionalised calcium carbonate (FCC) using mechanochemical activation (vibrational ball milling). The solid-state characteristics and physical…
