Omyapharm® for enhanced ODTs

In a recent study1 , scientists confirmed the ability of Omyapharm® to formulate orally disintegrating tablets (ODTs) with enhanced mouthfeel and examined their acceptability among healthy volunteers.

The multifunctional excipient from Omya is a highly structured mineral based on calcium carbonate and calcium phosphate. The study found that the tablets were well accepted by the volunteers and – in correlation with the in vitro model – disintegrated fast in vivo. Additionally, the compactibility and the physical stability of the tablets were preserved, delivering the high porosity required to absorb the liquid necessary for disintegration. These findings lead to the conclusion that Omyapharm® is a highly suitable excipient for ODT dosage forms with a pleasant mouthfeel.

ODTs are a comfortable and safe drug delivery method beneficial for all patient age groups. The main challenge in ODT development is simultaneously to ensure fast disintegration time, physical stability, taste masking, acceptable mouthfeel as well as a cost-effective production process. This study proves that Omyapharm® as an excipient can be successfully formulated into ODTs without any unpleasant sensation in the mouth. It combines good compactibility with a fast disintegration time, thanks to the high porosity and specific surface properties of the highly structured mineral. This results in harder tablets at low compression forces.

Omyapharm® 500-OG can be effectively formulated into tablets via dry granulation (roller compaction). Because of their high mechanical strength, the resulting tablets can be filled in conventional packaging, thus reducing costs and potential difficulties during the conditioning process. Alongside fast disintegrating formulations such as orally dispersible tablets and granules, the mineral excipient is also suitable for use in conventional tablets and capsules.
