Microwave-induced in situ drug amorphization using a mixture of polyethylene glycol and…
The use of a mixture of polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP) was investigated for microwave-induced in situ amorphization of celecoxib (CCX) inside compacts. Such amorphization requires the presence of a dipolar excipient in the formulation to ensure heating of the compact by…

The Effect of Process Variables and Binder Concentration on Tabletability of Metformin Hydrochloride…
In twin screw melt granulation, granules are produced by passing mixtures of drug substances and polymeric binders through twin screw extruder such that temperatures are maintained below melting point of drugs but above glass transition of polymers used, whereby the polymers coat surfaces of drug…

Combination of PAT and mechanistic modeling tools in a fully continuous powder to granule line:…
Comprehensive understanding of an integrated continuous pharmaceutical technology was achieved in this study by a combining design of experiments and mechanistic modeling-based simulations. The powder to granule line consisted of twin-screw wet granulation, vibrational fluid-bed drying and milling.…

Achieving gastroresistance without coating: Formulation of capsule shells from enteric polymers
Capsules are a widely used oral dosage form due to their simplicity and ease of manufacture. They are equally popular for both pharmaceutical and nutraceutical products and since they do not need extensive formulation development, it is a dosage form of choice for new drugs undergoing animal or…

The Development of Minitablets for a Pediatric Dosage Form for a Combination Therapy
Minitablets are an appealing option for an age-appropriate pediatric dosage form. In particular, for combination therapies where multiple active ingredients are dosed simultaneously, the use of minitablets will enable independent adjustments of each dose. The work presented describes the development…

Formulation and process strategies to minimize coat damage for compaction of coated pellets in a…
Compaction of multiple-unit pellet system (MUPS) tablets has been extensively studied in the past few decades but with marginal success. This study aims to investigate the formulation and process strategies for minimizing pellet coat damage caused by compaction and elucidate the mechanism of damage…

Synergistic application of twin-screw granulation and selective laser sintering 3D printing for the…
This study demonstrated the first case of combining a novel continuous granulation technique with powder-bed fusion-based selective laser sintering (SLS) process to enhance the dissolution rate and physical properties of a poorly water-soluble drug. Selective laser sintering and binder jetting 3D…

Design and characterisation of an amorphous formulation of nifedipine for the treatment of autonomic…
Current treatment for autonomic dysreflexia (AD) involves rupturing a liquid-filled soft capsule of nifedipine to aid rapid drug release and absorption, however, this application is not covered under the manufacturer's license. The objective of the current work was to design a rapidly dissolving…
