Previous reports show ineffective transdermal delivery of ketorolac by nanostructured lipid carriers (NLCs). The aim of the present work was enhancement of transdermal delivery of ketorolac by another colloidal carriers, lipid nanocapsules (LNCs). LNCs were prepared by emulsification with phase transition method and mixed in a Carbomer 934P gel base with oleic acid or propylene glycol as penetr...

Abstract
 
 Background: Banyuwangi has the potential of diverse natural resources. One example plant that can be utilized is butterfly pea (Clitoria ternatea L.). The contents are phenolic acids, stilbenes (phytoalexins), flavanols, anthocyanins, flavonols and flavanones, polyphenols flavonoids. In this research, preparations were developed from extract into powder form to make it mor...

Hydrophobic grade fumed silicas are generally used in tabletting as lubricants. They are also found to retard the release of pharmaceutical actives. This is because of their hydrophobic nature, which gives good cohesive and adhesive properties. considering this point it was thought that they could be used as dry coating agents for solid dosages forms. The model drug selected for this work was p...
