In situ solvent removal-based Eudragit®L/dimethyl sulfoxide forming gel for periodontal pocket drug…
Periodontitis is a chronic inflammatory disease of gum resulting from Porphyromonas gingivalis infectious at periodontal pockets. In situ forming gel (ISG) effectively delivers the antimicrobial agents to this targeted site. This study was to develop the dimethyl sulfoxide (DMSO) removal-based ISGs…

Exploration of theoretical and practical evaluation on Kollidon®SR matrix mediated amorphous…
The selection of an appropriate polymer for the preparation of amorphous solid dispersions via hot-melt extrusion (HME) deals with the study of various solid-state properties of drugs and polymers. Hence, before going to HME, it is necessary to have appropriate knowledge of drug-polymer miscibility,…

Towards a better understanding of thermally treated polycarbophil matrix tablets for controlled…
Polycarbophil (POL), a polyacrylic acid cross-linked with divinyl glycol, is widely used in semisolid and solid dosage forms. When undergoing a thermal treatment in the range 120–160 °C, POL shows interesting morphological modifications, related to changes in physical properties, such as swelling of…
