Abstract:
A carbamazepina (5H-dibenz[b, f]azepina-5-carboxamida) é um anticonvulsivante frequentemente utilizado no Brasil e em vários países. Ela apresenta quatro formas polimórficas e um di-hidratado, sendo ativa a Forma III. Entretanto, essa forma é altamente higroscópica podendo converter-se ao di-hidratado, menos ativo biologicamente. Nesse trabalho propõem-se avaliar o comportamento térmico da forma hidratada, visando à recuperação da forma ativa, por aquecimento. Para tanto, foi feito um estudo do comportamento térmico por TG/DTG-DTA e DSC em atmosfera dinâmica de ar e nitrogênio que evidenciou u

Spiral jet milling is a size reduction process used in various industries, ranging from paints to food and pharmaceuticals. It has great benefit in the pharmaceutical industry due to its ability to reduce particulate solids to micron sizes and narrow size distributions. Despite its heavy usage, the underlying size reduction mechanism of the mill is not well understood. However it is generally known that the milling behaviour is dependent on the grinding conditions of the mill, as well as the materials physical and mechanical properties.

Abstract:
Roll compaction is a dry granulation method. In the pharmaceutical industry it assists in binding tablet ingredients together to form a larger mass. This is conducted to ease subsequent processing, decrease dust, improve flowability, improve material distribution, more suitable for moisture and heat sensitive materials than wet granulation methods, minimises operating space and suited for a continuous manufacturing set-up. In pharmaceutical roll compaction various types of powder material mixtures are compacted into ribbon that are subsequently milled and tableted. The aim of this research is

Abstract:
This thesis concerns investigations of novel pressurised metered dose inhaler (pMDI) formulations containing tiotropium (Tio) in association with a secondary particulate (SP). A number of formulation and hardware variables were studied using in vitro methods to determine their influence on the performance of these novel formulations. Initial studies indicated that Tio was practically insoluble in HFA propellants and its solubility was not increased under raised moisture levels during long-term stability tests. Formulations with L-leucine (Leu) or lactose (Lac) as SP’s were investigated in Tio:

No capítulo I pretende-se avaliar a segurança dos excipientes utilizados nos medicamentos genéricos numa população pediátrica. Os medicamentos genéricos podem diferir do medicamento de referência em termos dos excipientes presentes nas suas formulações. A informação sobre a exposição da população pediátrica aos excipientes é escassa e dispersa, não ex

Abstract:
A detailed, fundamental understanding of the surface properties of molecular crystals and their interaction with adsorbing molecules (e.g. excipients) is important for tailoring the stability of formulations and the bioavailability of Active Pharmaceutical Ingredient (APIs). Few fundamental experimental studies with surface sensitive probes have been carried out for organic molecular crystals. X-ray photoelectron spectroscopy (XPS) is an established surface analysis method in the fields of adsorption, catalysis and surface chemistry of inorganic crystals. It has high surface sensitivity, probi

Abstract:
D'un grand intérêt industriel, la modification de surface des particules par enrobage s'obtient en voie sèche par différents procédés qui génèrent des forces mécaniques conduisant à des interactions physico-chimiques entre particules. Dans ce travail, deux extraits végétaux (prêle et harpagophyton) ont été enrobés avec du stéarate de magnésium et de l'Aérosil®R972 pour diminuer leur hygroscopicité, en utilisant un Hybridizer. L'enrobage des particules est visualisé au MEBE. Les effets du traitement sur l'hygroscopicité sont évalués (DVS, comparaison des produits au MEBE sous atmosphère humide)
