Tribology provides an in vitro tool that correlated to in vivo sensory data on the mouthfeel of coated tablets

Tribology is an emerging technique in the pharmaceutical field for texture and mouthfeel studies. Due to its relevance oral sensory perception, tribology supports development of novel products food industry. This study explores as a tool optimise ease swallowing coatings coated tablets. We measured lubricating properties eight using two methods: surface thin film tribology. As science more advanced studies, methods were developed from this with intention mimic tablet ingestion. Further, link between tribological measurements evaluation tablets obtained by human panel was explored. have demonstrated that discrimination different feasible. The viscosity, solubility composition coating formulations played important factor lubrication. For first time, used analyse conventional linear relationship i.e. slipperiness stickiness, demonstrated. has potential become valuable formulation characterise behaviour context perception.
