In the context of continuous pharmaceutical oral dosage manufacturing, a control system is essential to ensure that the critical quality attributes (CQAs) are maintained within the regulatory constraints by mitigating variations generated in upstream operations. Such a system is essential to the Quality by Design (QbD) paradigm shift, which can ensure predefined end quality attributes are achieved within an optimal economic and time bracket. In this work, an advanced model predictive control...

Purpose The aim of our study was development of advanced third generation Curcumin self microemulsifying composition solid dispersion (Cur SMEC-SD) with high drug loading, improved stability, rapid in-vitro dissolution and enhanced bioavailability for improved therapy of rheumatoid arthritis. Method The Cur SMEC-SD comprising polymers (KollidonVA64[KVA], Eudragits, HPMC and Soluplus) and self microemulsifying composition of surfactant:co-surfactant:oil were coated onto rapidly disintegrating...

This study investigated the impact of macro-scale carrier surface roughness on the performance of dry powder inhaler (DPI) formulations. Methods Fluid-bed processing and roller compaction were explored as processing methods to increase the surface roughness (Ra) of lactose carrier particles. DPI formulations containing either (a) different concentrations of fine lactose at a fixed concentration of micronized drug (isoniazid) or (b) various concentrations of drug in the absence of fine lactose...

Formulating drugs in the amorphous form is an attractive and promising strategy to overcome the poorly water soluble challenge commonly encountered in the newly discovered drug. The active research in the investigation of the properties and performance of drugs in the amorphous form has revealed the major challenges in developing amorphous formulations into marketable products. The three main challenges are development of analytical techniques to characterise the amorphous formulations,...

Purpose Properly charged particles can be used for effective lung targeting of pharmaceutical aerosols. The objective of this study was to characterize the performance of a new induction charger that operates with a mesh nebulizer for the production of highly charged submicrometer aerosols to bypass the mouth-throat and deliver clinically relevant doses of medications to the lungs. http://link.springer.com/article/10.1007/s11095-015-1682-6
