In vitro inactivation of SARS-CoV-2 using a povidone-iodine oral rinse.

Background: Healthcare professionals, especially dentists and dental hygienists, are at increased risk for contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through air-borne particles and splatter. This study assessed the in vitro virucidal activity of 0.5% (w/v) povidone-iodine (PVP-I) oral rinse against SARS-CoV-2 to demonstrate its utility as a professional oral rinse.

In Vitro Evaluation of the Virucidal Activity of Different Povidone-Iodine Formulations Against Murine and Human Coronaviruses.

Introduction: Polyvinylpyrrolidone-iodine (PVP-I) demonstrates broad-spectrum anti-infective activity and is available in different formulations for oral rinse and topical use in medical and personal care settings. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has underscored the need to supplement available preventive strategies.

Methods: We assessed virucidal activity of PVP-I formulations, including 0.

Cocrystallization via planetary milling: enhancing throughput of solid-state screening methods.

The application of a novel modified planetary mill, with the capacity to process 48 samples in parallel, to the rapid screening of pharmaceutical cocrystals via grinding is demonstrated for carbamazepine/saccharin, caffeine/oxalic acid, and caffeine/maleic acid cocrystals. Milling is performed directly in standard glass vials therefore no vessel decontamination is needed or sample loss occurs. Furthermore, successive sample processing can be employed without the need for additional material, making the system suitable for screening compounds of limited availability.
