Alcohol-induced dose dumping (AIDD) remains a serious challenge in the controlled delivery of high potency drugs, such as opioids, which requires extensive investigation and innovative solutions. Current technologies rely on ethanol-insoluble excipients, such as guar gum and sodium alginate, to counteract the increased solubility of hydrophobic polymeric excipients in ethanol. However, these excipients pose several shortcomings, such as high viscosity of coating dispersion, high solution temperature, rapid gelation, and heterogeneity of resulted film.

The objective of this study was to examine the impact of the physicochemical properties of the loaded drug or excipient, the concentration of Kollidon®SR (KSR), and the mechanical characteristics of KSR compacts on their disintegration times. Using disintegration apparatus, a two-hour constraint was chosen as the process's end point. Lactose-KSR compacts subjected to the highest compression pressure and Microcrystalline cellulose-KSR compacts with KSR concentrations exceeding 30% exhibited disintegration times of less than ten minutes.

The application of three-dimensional printing (3DP) in the pharmaceutical industry brings a broad spectrum of benefits to patients by addressing individual needs and improve treatment success. This study investigates the sustained release properties of 3DP tablets containing Theophylline (TPH), which is commonly used to treat respiratory diseases and recently having a comeback due to its potential in the treatment of conditions like Covid-19. Since TPH is a narrow therapeutic window (NTW) drug with serious side effects in the event of overdose, the release properties must be observed particularly closely.

Background: The use of synthetic and semi-synthetic materials in drug delivery systems has associated drawbacks like costly synthesis, toxicity, and biocompatibility issues. Therefore, there is a need to introduce novel materials to overcome such issues. Naturally occurring and water-swellable polysaccharides are advantageous in overcoming the above-mentioned issues.

The current study was conducted to evaluate and analyze the effect of alginate, itaconic acid, and N,N'-methylene bisacrylamide in formulation of a novel alginate based microgels for sustained release of theophylline. The fabricated microgels were characterized by PXRD, SEM, FTIR, TGA and DSC respectively. FTIR revealed that alginate reacted with itaconic acid during polymerization reaction and confirmed the overlapping of itaconic acid on the backbone of alginate.
