Recent studies have demonstrated polymer films to be a promising platform for delivery of poorly water-soluble drug particles. However, the impact of critical material attributes, for example plasticizer, on the properties of and drug release from such films has yet to be investigated. In response, this study focuses on the impact of plasticizer and plasticizer concentration on properties and dissolution rate of polymer films loaded with poorly water-soluble drug nanoparticles. Glycerin, triacetin, and polyethylene glycol were selected as film plasticizers. Griseofulvin was used as a model Biopharmaceutics Classification System class II drug and hydroxypropyl methylcellulose was used as a film-forming polymer. Griseofulvin nanoparticles were prepared via wet stirred media milling in aqueous suspension. A depression in film glass transition temperature was observed with increasing plasticizer concentration, along with a decrease in film tensile strength and an increase in film elongation, as is typical of plasticizers. However, the type and amount of plasticizer necessary to produce strong yet flexible films had no significant impact on the dissolution rate of the films, suggesting that film mechanical properties can be effectively manipulated with minimal impact on drug release. Griseofulvin nanoparticles were successfully recovered upon redispersion in water regardless of plasticizer or content, even after up to 6 months’ storage at 40 °C and 75% relative humidity, which contributed to similar consistency in dissolution rate after 6 months’ storage for all films. Good content uniformity (<4% R.S.D. for very small film sample size) was also maintained across all film formulations.
Background: The community misunderstands mental illness, resulting in stigmatizing attitudes toward persons with mental illness. High mental health literacy (MHL) among Accredited Social Health Activists (ASHA) workers can help spread mental health awareness to the community. The study aimed to assess the attitudes of ASHA workers toward the mentally ill. Method: A cross-sectional survey was conducted among ASHA workers in the city of Ahmedabad using the Community Attitude toward Mentally Ill (CAMI) scale – Gujarati version. Census sampling was used to collect data from ASHA workers at various Urban Health Centers (UHC). We analyzed 265 responses. Results: The mean (SD) of authoritarianism (AU), benevolence (BE), social restrictiveness (SR), and community mental health ideology (CMHI) subscales were 29.77(3.35), 35.33(3.78), 34.55(3.49), and 37.15(4.42), respectively (a higher mean suggests a negative attitude in the AU and SR subscales and a positive attitude in the BE and CMHI subscales). Conclusion: Although ASHA workers displayed goodwill and a welcoming attitude on the BE and CMHI subscales, they showed negative and stigmatizing attitudes on certain items of the AU and SR subscales. This necessitates a widespread mental health education campaign and training program for them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
