The pharmacokinetic-pharmacodynamic (pk-pd) characterization of the in vivo antinociceptive interaction between (+)-O-desmethyltramadol [(+)-M1] and (-)-O-desmethyltramadol [(-)-M1], main metabolites of tramadol, was studied in three groups of rats. (+)-M1 and (-)-M1, both with different pd properties, were studied under steady-state and nonsteady-state(More)
In this work three DNA-chitosan nanoparticle formulations (Np), differing in the molecular weight (MW; 150 kDa, 400 kDa, and 600 kDa) of the polysaccharide, were prepared and administered by two different administration routes: the hydrodynamics-based procedure and the intraduodenal injection. After the hydrodynamic injection, DNA-chitosan nanoparticles(More)
Bioadhesive nanoparticles have been proposed as carriers for the oral delivery of poorly available drugs and facilitate the use of this route. This work summarises some experiments describing the bioadhesive potential of Gantrez nanoparticles fluorescently labeled with rhodamine B isothiocyanate. The adhesive potential of Gantrez was found to be stronger(More)
BACKGROUND Palonosetron is a potent second generation 5- hydroxytryptamine-3 selective antagonist which can be administered by either intravenous (IV) or oral routes, but subcutaneous (SC) administration of palonosetron has never been studied, even though it could have useful clinical applications. In this study, we evaluate the bioavailability of SC(More)
