- A administração na mucosa bucal como uma estratégia alternativa à via oralPublication . Dias, Sandra; Figueiras, Ana; Barata, Pedro; Oliveira, Rita; Santos, Delfim; Veiga, Franciscoo principal objectivo deste trabalho foi realizar uma revisão geral sobre o mecanismo de mucoadesão, tendo em consideração aspectos tais como, as teorias explicativas de tal mecanismo, assim como os passos envolvidos no mecanismo de acção. De seguida, foi feita uma abordagem sobre polímeros bioadesivos, tendo sido expostos alguns resultados práticos no sentido de avaliar a força bioadesiva, o trabalho bioadesivo, bem como índice de swelling, de forma a obter uma matriz mucoadesiva com características optimizadas.
- Development of a platform to align education and practice: bridging Academia and the profession in PortugalPublication . Alves da Costa, Filipa; Martins, Ana Paula; Veiga, Francisco; Ramalhinho, Isabel; Sousa Lobo, José Manuel; Rodrigues, Luís; Granadeiro, Luiza; Castro, Matilde; Barata, Pedro; Gomes, Perpétua; Seabra, Vítor; Caramona, Maria MargaridaLimited fitness for practice may result from a mismatch between education and practice. Aiming to meet the common interests of academics and practitioners, the Portuguese Pharmaceutical Society (PPS) developed the Education and Practice Platform (EPP). The EPP includes one representative from each pharmacy faculty, and all Councils of Speciality Boards of Practice. Brainstorming with involved parties enabled sharing of interests, concerns and identifying a common path. Aims, mission, vision and values were set. The EPP's mission is to: act as an enabler to foster the quality and adequacy of education through sharing best practices, ultimately leading to facilitate professional integration, and to foster quality development in teaching practices with recognition for autonomy in freedom to teach and to learn. Its vision is an alignment of education and practice with the PPS' statutes to ensure validation of the competences defined for each practice area, and compliance with international guidance. Key performance indicators (KPIs) were set. Activities developed include the creation of a national forum to discuss education and practice, development of workshops on teaching methods and pharmacy internships, enhanced representation in international events and response to global and national requests. Ongoing work focuses on the creation of a common training framework in hospital and community pharmacy practice adapted to Portugal. The EPP is a worldwide case study, encouraging the development of discussion contributing to an open climate of sharing best practices, indirectly leading to foster a better alignment between education and practice. Many of these results are so far intangible in scientific terms but worth describing.
- Veiculação de fármacos para o cólonPublication . Barata, Pedro; Oliveira, Rita; Santos, Delfim; Strusi, OrazioLuca; Veiga, FranciscoA veiculação de fármacos para o cólon tem atraído a atenção de muitos investigadores interessados no tratamento de patologias locais e no seu potencial para a veiculação de proteínas e peptídeos. Para desenvolver estes sistemas é fundamental compreender o cólon enquanto local de veiculação de fármacos, em particular a sua capacidade de absorção e o tempo necessário para o atingir. Dois tipos de abordagens podem ser utilizados, libertação retardada ou libertação específica no cólon. O primeiro caso é menos específico e consiste em formulações preparadas de forma a retardar a libertação de fármaco até o sistema farmacêutico atingir o cólon. O segundo caso explora as propriedades de pH, actividade enzimática e pressão intraluminal do cólon para promover a libertação colónica de fármacos. Colon targeting has been attracting interest for those interested in treating local pathologies and administrating proteins and peptides. In order to develop these systems a perfect understanding of the colonic region is compulsory. two main strategies are used: delayed release and specific release. the first one, less specific, consists in postponing release from the system until it reaches de colon. the second one uses colon properties as pH, enzymatic activity and intraluminal pressure to trigger colonic drug release.
