Effectiveness and Safety of Enoxaparin Versus Unfractionated Heparin as Thromboprophylaxis in Hospitalized COVID-19 Patients: Real-World Evidence.

Background: Coronavirus 2019 (COVID-19) patients are at risk of thrombosis. Literature that compares the effectiveness of enoxaparin to unfractionated heparin (UFH) in COVID-19 patients is scarce.

Objective: We aimed to evaluate the effectiveness and safety of enoxaparin compared with UFH when used at their standard/intermediate dosing in COVID-19 patients.

Formulation of Apigenin-Cyclodextrin-Chitosan Ternary Complex: Physicochemical Characterization, In Vitro and In Vivo Studies.

The current investigation was performed with an aim to improve the aqueous solubility, dissolution rate, and thus the biological activity of apigenin (APG) using the solubilizers hydroxypropyl beta-cyclodextrin (HPβCD) and chitosan (CTSN). A binary and ternary inclusion complexes of APG with HPβCD and CTSN were prepared by physical mixing, fusion, and solvent evaporation methods. The liquid state characterization of the APG, the solubilizers, and the physical and chemical interactions between them was done through phase solubility approach.
