In this work calcium stearate (CaSt) multi-particulates loaded with codeine phosphate (COP) were developed in an attempt to provide extended release (ER) combined with alcohol dose dumping (ADD) resistance. The pellets were prepared via wet/extrusion spheronization and ER characteristics were obtained after fluid bed drying at 30 °C. Pore blockers (i.e., xanthan, guar gum and TiO2) were integrated to control the uptake of ethanolic media, the CaSt swelling and consequently, the COP release....

Novel orally disintegrating system based on multiparticulate form was developed, offering an alternative to encounter major issues in the design of dosage form for pediatric patients, i.e. the difficulty in swallowing large solid dosage form (tablet or capsule), and the requirement to cover a broad range of doses for different age groups. Microcrystalline cellulose-based pellets containing acetaminophen were prepared via extrusion/spheronization followed by freeze-drying. More

Several studies have shown the potential use of Ilex paraguariensis in developing products with the aim to protect biological systems against oxidative stress-mediated damages. In the same way, technological studies have demonstrated the feasibility of obtaining dry products, by spray-drying process, from aqueous extracts of I. paraguariensis in laboratory. More
