Therapeutic Efficacy

Animal-based testing is important for understanding the performance, mechanism, and translational capacities of floating tablets and in-vitro testing for stomach retention, which is the focus of the current review.  With a limited window for absorption in the upper gastrointestinal tract, drug delivery systems (FDDS) are designed to improve the residence time, bioavailability, and controlled release of medications.  The recipes that employed gas-producing agents like sodium bicarbonate and citric acid, as well as hydrophilic polymers like HPMC, carbopol, and sodium alginate, demonstrated exceptional floating properties with a lag time of less than 12 hours. In vitro research studies showed sustained release profiles along the zero-order or non-Fickian kinetics, whereas in vivo testing in albino rats and rabbits showed long gastric retention and better pharmacokinetic results. Gastric safety and biocompatibility was confirmed by histopathological assessments. Direct compression was determined to have the best formulation through comparative analysis based on stable and efficient formulations compared to wet granulation. All in all, animal tests will be a critical preclinical base to determine optimal proportions of polymers, buoyancy, and release characteristics which will make floating pills safe and effective when applied to the clinical setting.

Poor water solubility is still a big problem in medication development since it typically makes oral formulations less bioavailable and less effective at treating diseases. The goal of this project was to create and test solid lipid nanoparticles (SLNs) as a new way to deliver medications that don't dissolve well. Four SLN formulations were made and tested using a hot homogenization followed by ultrasonication method. The tests looked at the size of the particles, the polydispersity index (PDI), the zeta potential, the entrapment efficiency, the drug loading, and the in vitro drug release. The results showed that higher concentrations of surfactants and lipids made the particles smaller, trapped more drugs, and released them over a longer period of time. Formulation F4 had the best performance, with a particle size of 130 nm, an entrapment efficiency of 88%, and a drug release rate of 85% at 24 hours. Statistical analysis showed that there were big differences across the formulations (p
