Abstract:


Aim: The present study was aimed to developed and optimize the self-nano emulsifying drug delivery system of α-pinene (ALP-SNEDDS) and evaluate its in-vivo anti-Parkinson's activity.

Background: Different lipid-based drug delivery technologies have been researched to upgrade drug bioavailability and expand their clinical adequacy upon oral administration. Self-emulsifying drug delivery systems (SEDDS) have pulled in developing the interest specifically for self nano emulsifying drug delivery systems (SNEDDS).

Objective: The present work was attempted to improve the bioavailability of the ALP by defining the role of self-nano emulsifying formulations for its neuroprotective effect.

Methods: Miscibility of the ALP was estimated in various excipient components to select the optimized combination. Self-nano emulsification, thermodynamic stability, the effect of dilution on robustness, optical clarity, viscosity, and conductivity tests were performed. The in-vivo anti-Parkinson's activity of the ALP-SNEDDS formulations were done using Pilocarpine antagonism induced Parkinsonism in rodents. Behavioral tests like tremulous jaw movements, body temperature, salivation, and lacrimation are performed.

Result: Two optimized formulations, composed of Anise oil, Tween 80, and Transcutol-HP of Oil: Smix ratio (4:6 and 3:7) were selected. The Smix ratio for both the formulation was 2:1. The particle size was found to consistent with the increase in dilution. The mean negative zeta potential of the formulations was found to be increased with an increase in dilution. The TEM images of the formulations revealed spherical shape of the droplet. The in-vitro drug release profile was found to be significant as compared to plain ALP suspension.

Conclusion: The results of in-vivo studies indicate that nanosizing and enhanced solubilization of oral ALP-SNEDDS formulations significantly improved the behavioral activities compared to plain ALP suspension.
