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…

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…

Most microbial infectious diseases can be treated successfully with the remarkable array of antimicrobials current available; however, antimicrobial resistance, adverse effects, and the high cost of antimicrobials are crucial health challenges worldwide. One of the common efforts in addressing this…

Hydroxypropyl methylcellulose (HPMC) is one of the most important hydrophilic ingredients used in hydrogel matrices preparation (tablets or granules). In this work, HPMC was used to produce granules loaded with hydrophilic and hydrophobic active molecules to investigate their possible use as release…

In spite of the large research efforts in the past two decades, it is still difficult, if possible at all, to predict what manufacturing technology will lead to the best amorphous solid dispersions (ASDs) in terms of drug to polymer ratio (“drug loading”) and physical stability. In general, ASDs can…

Hydrophobic and hydrophilic thermoplastic poly(urethane) (TPU) mixtures offer the opportunity to tune water swelling capacity and diffusion rate for drugs exhibiting broadly different properties. We sought to (1) assess the range of drug diffusion rates achieved by varying hydrophilic-to-hydrophobic…

Flowability is a key consideration during the formulation and process development of oral solid dosage forms as it can have a critical impact on product quality. With a limited number of examples available in the literature, there is a need to better understand and share the typical flow properties…
