Introduction Pellets are versatile dosage forms for many actives. To control drug dissolution profiles, they can be prepared with different coatings. Coated multiparticulate systems are known to show less variation in drug release than single unit formulations. Furthermore, dose dumping effects due…

Transdermal administration remains an active research and development area as an alternative route for long-acting drug delivery. It avoids major drawbacks of conventional oral (gastrointestinal side effects, low drug bioavailability, and need for multiple dosing) or parenteral routes (invasiveness,…

Abstract Glidant used for the purpose of powder flowability enhancement is well known within the pharmaceutical industry to improve tablet manufacturing. Despite the widespread use of glidant for this purpose, the effect of glidant on the effect of tableting behavior is not well studied. To address…
