Development and in vivo evaluation of an innovative “Hydrochlorothiazide-in Cyclodextrins-in Solid Lipid Nanoparticles” formulation with sustained release and enhanced oral bioavailability for potential hypertension treatment in pediatrics

An innovative pediatric oral formulation of hydrochlorothiazide (HCT) (2mg/mL), endowed with improved bioavailability and sustained release properties and suitable for the hypertension treatment in pediatric patients, was developed by combining the drug-cyclodextrin complexation and the incorporation of the complex into Solid Lipid Nanoparticles (SLN). Precirol®ATO5-based SLN, with two different surfactants (Pluronic®F68 and Tween®80) loaded...
