Blood-brain barrier (BBB) together with enzymes restricts the entry of substances for maintaining the internal milieu of the brain. Because of the presence of multiple endogenous transporters, BBB allows a selective entry of nutrients and minerals across it and limits the entry of foreign substances like drugs as well as neuropharmaceutical agents. This(More)
The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. The recent developments of FDDS including the physiological and formulation variables affecting gastric retention, approaches to design single-unit and(More)
Now a day's intranasal (i.n) drug delivery is emerging as a reliable method to bypass the blood-brain barrier (BBB) and deliver a wide range of therapeutic agents including both small and large molecules, growth factors, viral vectors and even stem cells to the brain and has shown therapeutic effects in both animals and humans. This route involves the(More)
Ramipril nanoemulsion formulations were successfully prepared by the spontaneous emulsification method (titration method). Sefsol 218 was selected as the oil phase for the development of the formulation on the basis of the solubility studies. The differences in the droplet size between the formulations selected from the phase diagram was not statistically(More)
INTRODUCTION Natural products have seen a wide range of acceptability for the prevention and treatment of diseases throughout history. Resveratrol, a member of the stilbene family, has been found to potentially exhibit anticancer, antiangiogenic, immunomodulatory and cardioprotective activities as well as being an antioxidant. This is in addition to its(More)
The objective of the present study was to develop a nanocarrier based formulation of nadifloxacin and to investigate its in vitro antimicrobial effect against Propionibacterium acnes. Nanocarrier based microemulsion formulations were prepared by aqueous titration method, using oleic acid as oil phase, Tween-80 as surfactant and ethanol as co-surfactant in(More)
Silymarin, obtained from Silybum marianum is used for hepatoprotection and having poor aqueous solubility and low bioavailability. Therefore, it was thought to incorporate the drug into oil-in-water (o/w) based nanocarrier to increase its oral bioavailability. In the present study, o/w nanocarrier was prepared by titration method and was characterized for(More)
Nanostructured lipid carrier (NLC) is second generation smarter drug carrier system having solid matrix at room temperature. This carrier system is made up of physiological, biodegradable and biocompatible lipid materials and surfactants and is accepted by regulatory authorities for application in different drug delivery systems. The availability of many(More)
INTRODUCTION Betamethasone dipropionate (BD) has anti-inflammatory, immunomodulatory, and antiproliferative activity. The aim of the current work was to test the hypothesis that the addition of corticosteroid such as BD and a keratolytic agent such as salicylic acid in nanocarrier based microemulsions formulation would result in enhancement and sustaining(More)
The aim of the present study was to prepare and evaluate a rasagiline-loaded chitosan glutamate nanoparticles (RAS-CG-NPs) by ionic gelation of CG with tripolyphosphate anions (TPP). RAS-loaded CG-NPs were characterized for particle size, size distribution, encapsulation efficiency and in vitro drug release. The mean particles size, polydispersity index(More)
