Current Drug Delivery - Volume 19, Issue 7, 2022

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) is a highly contagious virus causing COVID-19 disease that severely impacted the world health, education, and economy systems in 2020. The numbers of infection cases and reported deaths are still increasing with no specific treatment identified yet to halt this pandemic. Currently, several proposed treatments are under preclinical and clinical investigations no Read More

Nanoparticles (NPs) have been widely used in drug delivery systems specifically for chemo-, radio-, photothermal, and photodynamic therapy. Due to the lack of selectivity toward tumor cells, the main target in therapies is to deliver drugs to cancer cells to reduce side effects. Gold nanoparticles (AuNPs) have been described as “promising nanocarriers for therapeutics” due to many properties such as low inherent toxicity, high w Read More

Introduction: The consumption of large amounts of ethanol can directly lead to acute gastric mucosal bleeding, edema, and erosion, while long-term drinking has been associated with gastric ulcers. Previous research has demonstrated that Har Gabur, a traditional Mongolian medicine, alleviates gastric ulcers through the physical adsorption of its carbon components. It is well known that the immune response has an im Read More

Background: Fenofibrate (FNB) is a commonly used hypolipidemic agent. However, the oral bioavailability of FNB is limited by slow dissolution due to its low solubility. Thus, investigations on novel FNB formulations are necessary for their use. Objective: The objective of this study is to enhance the oral bioavailability of FNB using optimized Nanostructured Lipid Carrier (NLC) formulations. Methods: Hot homogenization followed b Read More

Background: Asenapine maleate, an anti-schizophrenic drug, is a class II drug with low solubility and high permeability. This exerts a rate-limiting effect on drug bioavailability. Objective: To improve the solubility/dissolution rate of asenapine maleate and hence the bioavailability using the co-crystal approach. Methods: Co-crystals were prepared using the solvent evaporation method. Since the drug has Hbond acceptor count Read More

Introduction: Liquid Semisolid Matrix (LSSM) technology involves the filling of drugmixed gel in hard gelatin capsules for different applications. Methods: In continuation of our previous work on LSSM technology, 10% (w/w) of practically insoluble model drug, mefenamic acid was incorporated in gels of different poloxamers with 8% (w/w) SiO2. Results: Gels exhibited plasticity or pseudoplasticity along thixotropy at Read More
