Efficacy and Safety of Nasal Administration of “Na-no-L-DOPA” Based on PLGA Nanoparticles
نویسندگان
چکیده
Inclusion of L-DOPA, the standard Parkinson’s disease medication, into polymeric particles (PLGA) results in optimization the drug metabolism and increasing its bioavailability, significantly increases of physical endurance, better coordination and lower anxiety in Wistar rats, when chronically administered nasally.

Increasing the Efficiency of Parkinson's Disease Treatment Using a poly(lactic-co-glycolic acid) (PLGA) Based L-DOPA Delivery System
To compare the efficacy of L-DOPA administered intranasally in the form of nanoparticles (nano-DOPA) and in standard drug forms using a rat Parkinson's Disease (PD) model. L-DOPA-containing nanoparticles (250±50 nm) were synthesized using the double emulsion method. The efficacy of nano-DOPA therapy was studied in Wistar rats with 6-OHDA-induced PD. Drugs were administered daily, 0.35 mg/kg (by...
متن کاملNasal Immunization by (PLGA) Nanospheres Encapsulated with Tetanus Toxoid and (CpG-ODN)
In induction of systemic and mucosal immunity, particulate antigens are more effective than soluble antigens possibly because they are more efficiently endocytosed by mucosal-associated lymphoid tissue (MALT) M cells. In this study, we determined the systemic and mucosal immune responses in rabbits following intranasal immunization of tetanus toxoid TT and CpG-ODN encapsulated within PLGA nanos...

متن کاملPLGA, PLGA-TMC and TMC-TPP Nanoparticles Differentially Modulate the Outcome of Nasal Vaccination by Inducing Tolerance or Enhancing Humoral Immunity
Development of vaccines in autoimmune diseases has received wide attention over the last decade. However, many vaccines showed limited clinical efficacy. To enhance vaccine efficacy in infectious diseases, biocompatible and biodegradable polymeric nanoparticles have gained interest as antigen delivery systems. We investigated in mice whether antigen-encapsulated PLGA (poly-lactic-co-glycolic ac...

The aim of me present work was to investigate rhe potential utility of nanoparticles made of chitosan (CS) and also CS chemically modified with polyethylene glycol (CS-PEG) as new vehicles for improving na^al vaccine delivery. For mis purpose, diphtheria toxoid (DT) was chosen as a model antigen. DT was entrapped within nanoparticles made of CS of different molecular weight, and also made of C...
