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…

The aim of this study was to evaluate how the addition of hydrophobic inclusions to sustained-release pellet film coat can affect drug release. Sustained-release formulations, in particular multiparticulate systems are gaining popularity because they are able to reduce the dosing frequency of drugs…

Background: Oral bioavailability of gliclazide, a hypoglycemic drug, is hindered by its low aqueous solubility. Improvement of solubility will enhance dissolution rate and in turn the bioavailability. This research aimed to formulate the solid dispersed gliclazide using a novel polyethylene…

Nasal application of powder formulations has garnered attention because of its significant potential for systemic drug delivery. Because a powder drug must first diffuse from the formulation and dissolve in the nasal cavity fluid before transepithelial permeation, dissolution and diffusion are…

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…
