AI Article Synopsis
Article Abstract
The in vitro release rate of methoxsalen from three commercially available tablets and an experimental tablet were evaluated at pH 2 and 7, using the USP dissolution test. The experimental tablet and one commercial product showed that 74% of the labeled amount is released in 1 h and almost completely released after 3 h at pH 2 and 7. Two products showed that only 12 and 10% of the labeled amount was released in 1 h and a maximum of 25 and 23% after 3 h at pH 2. At pH 7, the percent released from these two products were slightly higher. These results correlate with the reported clinical effectiveness of one of the products showing fast methoxsalen release. Since exposure to long-wave UV radiation is carried out 1-3 h following methoxsalen oral administration, delayed release might explain the failure of some products to give satisfactory clinical results.

Continuous-flow phosphate removal using Cry-Ca-COS Monolith: Insights from dynamic adsorption modeling.

This study rigorously evaluates the adsorption performance of the Cry-Ca-COS monolith for phosphate removal in a column operation mode. Characterization of the material both before and after exhaustion in a continuous flow system (column form) showed no difference compared to results from a batch system (tablet form). The XPS results indicated that the adsorption mechanism of phosphate on the Cry-Ca-COS column involved surface microprecipitation and ligand exchange (inner-sphere complexation).

The pharmaceutical quality of freeze-dried tablets containing therapeutic bacteriophages against Pseudomonas aeruginosa and Staphylococcus aureus.

The preparation of a solid dosage form containing bacteriophages, which meets pharmaceutical requirements and ensures long-term stability of the phage effect, is significant for implementing phage therapy in practice. A commonly used method for processing phages into a solid form is freeze-drying into a (so-called) freeze-dried cake; however, to date there have been no studies examining the pharmacopeial parameters of freeze-dried tablets with bacteriophages. In this study, we describe the preparation and properties of freeze-dried tablets containing a cocktail of purified pseudomonal bacteriophage DSM 33593 from the genus Pbunavirus and staphylococcal bacteriophage DSM 33473 from the genus Kayvirus (10 PFU/tablet) as the active ingredient.

Synthetic Molecule Pharmaceutical Sciences, Genentech, Inc., 1 DNA Way, South San Francisco, CA, 94080, USA.
Purpose: The purpose of this study is to present a correlative microscopy-tomography approach in conjunction with machine learning-based image segmentation techniques, with the goal of enabling quantitative structural and compositional elucidation of real-world pharmaceutical tablets.
Methods: Specifically, the approach involves three sequential steps: 1) user-oriented tablet constituent identification and characterization using correlative mosaic field-of-view SEM and energy dispersive X-ray spectroscopy techniques, 2) phase contrast synchrotron X-ray micro-computed tomography (SyncCT) characterization of a large, representative volume of the tablet, and 3) constituent segmentation and quantification of the imaging data through user-guided, iterative supervised machine learning and deep learning.
Results: This approach was implemented on a real-world tablet containing 15% API and multiple common excipients.
