WebbAt pH 1.2, GDS exhibited greater swelling than erosion, and drug release was similar to GG and HPMC. This highlights the potential of GDS as a matrix for controlled release similar to HPMC and GG at pH 1.2 but with a more rapid release at pH 6.8. GDS may have wider application in reinforcing compacts with relatively low mechanical strength. cyhl77WebbPreliminary investigations were carried out on L-Phenylalanine (L-Phe) and four different CDs, including, (2-hydroxypropyl)-α-cyclodextrin (HPαCD), (2-hydroxypropyl)-β-cyclodextrin (HPβCD), heptakis(2,6-di-O-methyl)-β-cyclodextrin (DIMEB), and (2-hydroxypropyl)-γ-cyclodextrin (HPγCD), and results revealed that two β-CD derivatives … cyhme56cWebb25 nov. 2024 · Kleptose HPB (hydroxypropyl-β-cyclodextrin) was a kind gift from Roquette Frères (Lestrem, France).
