The aim of the current study is to optimize the bed fluidized coating process of mini tablets by means of an acoustic levitator. The optimized coating parameters, which have to be set in a fluidized bed reactor, can be determined by means of contactless levitation of a single mini tablet in an…

Oral drug delivery technology is mainly provided in the form of solid oral dosage forms (SODF) that have to be swallowed intact and move throughout the oro-esophageal system to release the drug content in the stomach or intestine. As there is growing evidence for an increasing prevalence of impaired…

Most pH-sensitive polymer coating studies for potential colonic delivery systems apply multiple layers to protect the active agent from degradation and early release in the stomach and small intestine. This study designed a single-coat pH-sensitive layer for colon-specific delivery with a potential…

Liquid-liquid phase separation (LLPS) occurs following amorphous solid dispersion (ASD) dissolution when the drug concentration exceeds the “amorphous solubility”, and is emerging as an important characteristic of formulations that may enhance the oral bioavailability of poorly soluble drugs. The…

Bioavailability, one of the prime pharmacokinetic properties of a drug, is defined as the fraction of an administered dose of unchanged drug that reaches the systemic circulation and is used to describe the systemic availability of a drug. Bioavailability assessment is imperative in order to…

To improve the dissolution and oral bioavailability of valsartan (VST), we previously formulated a supersaturable self-microemulsifying drug delivery system (SuSMED) composed of Capmul® MCM (oil), Tween® 80 (surfactant), Transcutol® P (cosurfactant), and Poloxamer 407 (precipitation inhibitor) but…
