Influence of rheological behavior of lactose powders on the weight consistency of tablets –…
The 12th APV PBP World Meeting took place from 28 – 31 March 2022 in Rotterdam. There was a poster section at the event where really interesting scientific posters were presented. Therefore we asked the presenting scientists if we could share their work in addition online with the Pharma Excipients…

Crystallization induced flower-like lactose as potential carriers for dry powder inhaler application
The study documents the flower-like lactose particles as potential carriers to improve Dry Powder Inhaler (DPI) efficiency. The lactose particles (LMx, LMf) are prepared by anti-solvent crystallization and compared with commercial lactose carriers (Inhalac 251; LMc). Formulations of 1.48% w/w drug…

The effect of excipient particle size on the reduction of compactibility after roller compaction
Developing a robust roller compaction process can be challenging, due to the diversity in process parameters and material properties of the components in a formulation. A major challenge in dry granulation is the reduction of tablet strength as a result of re-compaction of the materials. The aim of…

Technical insight into potential functional-related characteristics (FRCs) of sodium starch…
Functional-related characteristics (FRCs) are properties of excipients that can potentially influence one or more functions of that excipient in the final product. Knowledge of FRCs is important for formulation development and also to assess the risks of excipient variability on final product…

Preparation and Characterization of Inhalable Ivermectin Powders as a Potential COVID-19 Therapy
Ivermectin has received worldwide attention as a potential COVID-19 treatment after showing antiviral activity against SARS-CoV-2 in vitro. However, the pharmacokinetic limitations associated with oral administration have been postulated as limiting factors to its bioavailability and efficacy. These…

Effect of feed frame on lubricant sensitivity during upscaling from a compaction simulator to a…
Internal lubrication can be associated with reduced tabletability. Deformation mechanism, lubricant type, lubricant blending time and paddle speed (PS) of the forced feeder are known to be influenceable factors. This study investigated the effect of lubricant blending time and PS of forced feeders…

Sampling and diversion strategy for twin-screw granulation lines using batch statistical process…
Continuous manufacturing is now considered as a well-established technique by pharmaceutical companies. However, the limited number of filed applications reflects the complexity to translate a science that has been described in many publications to an actual drug product. Process stability…

Relationship between powder properties and uniformity of ribbon property using feeding guider…
Roller compaction is a continuous dry granulation process in which two counter-rotating rollers compress the powder. The feeding of powder to the compaction zone has a significant effect on product quality in the process. This work aims to improve ribbon property uniformity using new feeding guiders…

Influence of commonly used excipients on the chemical degradation of enalapril maleate in its solid…
The physicochemical stability of enalapril maleate was investigated in the presence of fourteen different excipients divided into four different classes. The extent of a drug-excipient interaction was investigated by following the chemical stability using HPLC. It was found that there is a certain…

Impact of Powder Properties on the Rheological Behavior of Excipients
With the emergence of quality by design in the pharmaceutical industry, it becomes imperative to gain a deeper mechanistic understanding of factors impacting the flow of a formulation into tableting dies. Many flow characterization techniques are present, but so far only a few have shown to mimic…
