Vitamin E Loaded Naringenin Nanoemulsion via Intranasal Delivery for the Management of Oxidative Stress in a 6-OHDA Parkinson's Disease Model.

Purpose: The present study is an attempt to develop a vitamin E loaded naringenin (NRG) Nanoemulsion (NE) for direct nose-to-brain delivery for better management of Parkinson's disease (PD).

Methods: The optimized NE was evaluated for efficacy in PD using multiple behavioral studies (including narrow beam test, muscular coordination test, grip strength test, forced swimming test, and akinesia test) in a rat model. Optimized formulation was evaluated for droplet size, polydispersity index (PDI), refractive index, transmittance, zeta potential, and viscosity.

Adaptation of Quality by Design-Based Development of Isradipine Nanostructured-Lipid Carrier and Its Evaluation for In Vitro Gut Permeation and In Vivo Solubilization Fate.

The present study demonstrated the systematic adaptation of quality by design-integrated approach for the development of novel nanostructured lipid carrier (NLC) of an anti-hypertensive drug isradipine (ISD) to address the inherent challenges such as low solubility and low oral bioavailability. Plackett-Burman design was used for preliminary screening of significant process and formulation variables (p <0.05), which were further processed using Box-Behnken design for the attainment of optimization goal that is, mean particle size (85.

Nanocarriers as treatment modalities for hypertension.

Hypertension, a worldwide epidemic at present, is not a disease in itself rather it is an important risk factor for serious cardiovascular disorders including myocardial infarction, stroke, heart failure, and peripheral artery disease. Though numerous drugs acting via different mechanism of action are available in the market as conventional formulations for the treatment of hypertension but they face substantial challenges regarding their bioavailability, dosing and associated adverse effects which greatly limit their therapeutic efficacies. Various studies have demonstrated that nanocarriers can significantly increase the drug bioavailability thereby reducing the frequency of dosing in addition to minimizing toxicity associated with high dose of the drug.

Brain delivery of buspirone hydrochloride chitosan nanoparticles for the treatment of general anxiety disorder.

The present work discusses the preparation, characterization and in vivo evaluation of thiolated chitosan nanoparticles (TCS-NPs) of buspirone hydrochloride (BUH) for brain delivery through intranasal route. TCS NPs were prepared by ionic gelation method and characterized for various parameters. The NPs formed were having particle size of 226.

Nanostructured lipid (NLCs) carriers as a bioavailability enhancement tool for oral administration.

Context: Nanostructured lipid carrier (NLCs) is the second generation solid lipid nanoparticles (NPs) made up of physiological, biocompatible, biodegradable, non-sensitizing and non-irritating lipids.

Objective: The main objective of this review is to explore the role of NLCs system for delivering drugs by oral route and thus increasing the oral bioavailability.

Methods: The present review article highlights the definition and types of NLCs and their importance as colloidal carriers including the production techniques and their formulation.
