Article
Accés restringit per política de l'editorialtUnderstanding the phase behavior of an active pharmaceutical ingredient in a drug formulation isrequired to avoid the occurrence of sudden phase changes resulting in decrease of bioavailability in amarketed product. ... -
Crystal structure and solid-state studies of aged samples of tienoxolol, an API designed against hypertension
Teulon, Jean-Marie; Mahé, Nathalie; Do, Bernard; Nicolaï, Béatrice; Rietveld, Ivo B.; Barrio Casado, María del; Tamarit Mur, José Luis; Céolin, René; Ghéchot, Christophe (2012)
Article
Accés restringit per política de l'editorialAging of drug molecules is generally studied following regulatory procedures, i.e. under forced conditions and for relatively limited storage time; therefore naturally aged samples are rare and provide scientific reference ... -
Enantiomer resolution by pressure increase: inferences from experimental and topological results for the binary enantiomer system (R)- and (S)-mandelic acid
Rietveld, Ivo B.; Barrio Casado, María del; Tamarit Mur, José Luis; Do, Bernard; Céolin, René (2011-11-02)
Article
Accés restringit per política de l'editorialIn pharmacy, racemic compounds are often problematic, because generally only one of the enantiomers possesses therapeutic activity and it is often difficult to separate them. Even though this problem is likely as old ... -
Investigating therapeutic usage of combined Ticagrelor and Aspirin through solid-state and analytical studies
Sadou Yayé, Hassane; Rietveld, Ivo B.; Barrio Casado, María del; Secrétan, Philippe-Henri; Faucheron, Antoine; Karoui, Maher; Tilleul, Patrick; Yagoubi, Najet; Do, Bernard (2017-09-30)

Article
Accés restringit per política de l'editorialSolid-state properties of active pharmaceutical compounds are closely related to their dissolution behavior and bioavailability, and understanding their phase behavior leads to better control in the drug formulation process. ... -
Overall stability for the ibuprofen racemate: experimental and topological results leading to the pressure-temperature phase relationships between its racemate and conglomerate
Rietveld, Ivo B.; Barrio Casado, María del; Do, Bernard; Tamarit Mur, José Luis; Céolin, René (2012-05-10)
Article
Accés restringit per política de l'editorialEnantiomer resolution is much sought after for pharmaceutical applications, because many optically active drug molecules have only one pharmaceutically active enantiomer. Although it is always possible to force separation, ... -
