Just a quick post about at the work we presented at the UK Pharm Sci conference this year….
The authors found that a gradient HPLC method developed to be within the manufacturer’s column pH tolerance produced an unpredictable degradation of the stationary phase. The mechanism of silica degradation at high pH remains unclear and contradicts known physico-chemistry, yet is an important part of modern, efficient HPLC analysis.
Blister packs are commonly used to package hard gelatin capsules. Shelf life restrictions of the blister pack components can be problematic for low volume users due to the requirement to purchase larger quantities. This work investigated the physical and chemical properties of blister pack foils to determine if a change in their nature occurred when the expiry date was exceeded.
The rheological properties of pharmaceutical formulations intended for liquid fill hard gelatin capsules is fundamental for their filling performance. Here we used the rheological characteristics of particulate drug formulations to develop formulations suitable for automated capsule filling.
