Proveris Scientific announces joint scientific poster presentation with H&T Presspart at RDD 2020 Digital Conference
Proveris Scientific Corporation, a leading provider of services and technology to advance the science of spray and aerosol products, today announced that on April 26 at RDD 2020 Digital Respiratory Drug Delivery Conference, Proveris will present a joint poster with H&T Presspart, Blackburn, Lancashire, UK entitled, “The Effect of Ethanol Concentration on pMDI Evaporation Fraction.”
The subject of the study is introducing a technique to quantify the evaporation fraction using a novel measurement method applied to a time-synchronized image sequence of the aerosol spray from pressurized metered dose inhalers (pMDIs). In order to demonstrate the effectiveness of the technique, the study used non-commercial pMDI product samples with three different ethanol concentrations, but identical devices provided by H&T Presspart. The results show the higher the ethanol concentration, the lower the evaporation fraction.
The FDA May 2019 product specific guidance for beclomethasone dipropionate delivered by MDI lists evaporation rate of the aerosol as an in vitro characterization study that is representative and/or predictive of the clinical effect in the deep lung. Due to the aerosolization mechanism of pMDI products, aerodynamic properties such as evaporation rate impact drug delivery and lung deposition. Currently, there are limited evaporation rate studies and technologies available to effectively study the variable bulk mass of aerosols without interrupting the spray.
The non-impaction laser imaging technology of the well-established Proveris SprayVIEW® measurement system offers meaningful insight into drug product evaporation. The approach is significant as it offers Generic OINDP developers a tool for performing in vitro bioequivalence comparisons between Test and Reference products.
