Tricalcium citrate (TCC) was characterized as a tableting excipient for direct compression (DC) and dry granulation (DG). Significance: Brittle materials usually lead to tablets of inferior mechanical strength compared to plastic deforming materials. A brittle material exhibiting a high tabletability with the ability to retain that behavior during recompression would represent a valuable alternative to the commonly used microcrystalline cellulose. Methods: Tablets of TCC and other common...

Monoclinic paracetamol (PA) is notorious as a poorly compactible model drug. Polyvinylpyrrolidone (PVP) is a polymer that can act as an effective binder to improve the mechanical properties of PA. It is surprising however that the role of mixing conditions on the physicochemical and mechanical properties of PA–PVP mixtures has not been reported previously. The results of this work showed that PA–PVP mixtures containing 5% (w/w) PVP prepared using high energy mixing conditions had...

Tricalcium citrate (TCC) was characterized as a tableting excipient for direct compression (DC) and dry granulation (DG). SIGNIFICANCE: Brittle materials usually lead to tablets of inferior mechanical strength compared to plastic deforming materials. A brittle material exhibiting a high tabletability with the ability to retain that behaviour during recompression would represent a valuable alternative to the commonly used microcrystalline cellulose (MCC). METHODS: Tablets of TCC and other common...

Purpose To investigate how excipient matrix affects punch sticking propensity of active pharmaceutical ingredients (API), with the focus on the effect of bonding interactions between API-API (F2) and API-excipient (F3). Method Sticking kinetics of direct compression formulations, consisting of 20% of celecoxib (CEL) or ibuprofen (IBN) indifferent excipient matrices, i. e., microcrystalline cellulose (Avice l PH102 and Avicel PH105 dry coated with nano-sized silica (PH105(n)), hypromellose (K15...

As the pharmaceutical industry increasingly adopts continuous manufacturing technology, significant attention must be paid to process analytical technology (PAT), process integration, and process control. Published information is no substitute for hands-on comprehensive training, which is critical to implementing and operating continuous pharmaceutical manufacturing systems effectively and efficiently. In this article, an intensive hands-on training course has been developed and implemented at...

Faecalibacterium prausnitzii was previously recognized for its intestinal anti-inflammatory activities and it has been shown less abundant in patients with chronic intestinal diseases. However, the main problems encountered in the use of this interesting anaerobic microorganism are firstly its high sensitivity to the oxygen and secondly, its ability to reach the large intestine alive as targeted site.

Calcium phosphates have been used in the pharmaceutical technology for many years. They have many physical and chemical properties that make them ideal candidates for the production of solid oral dosage forms. They are mainly used as fillers in order to bulk up formulations however, the function of calcium phosphates goes far beyond mere filler and the adequate utilisation of their full functionality can support achieving the intended formulation goals.

The vulnerability of controlled release formulations when co-ingested with alcohol represents a current major concern of regulatory agencies. Dose dumping might occur when drugs and/or excipients exhibit higher solubility in ethanolic solutions compared to water.
