Purpose:
Bacopa monnieri (Brahmi; family Scrophulariaceae) is a well-known plant known for its nootropic activity. Delivery of Bacosides (active constituent) is limited at the site of action owing to the existence of blood-brain barrier
(BBB). In order to take the bacoside rich extract (BRE) across BBB, formulated solid lipid nanoparticles (SLNs) were used.
Objective:
The objective of this work was to evaluate the pharmacokinetic and pharmacodynamic behavior (in vivo potential) of the prepared SLNs containing BRE in comparison to BRE alone for the treatment of Alzheimer’s disease.
Methods:
Swiss albino male mice (25-30 gm) were used for the study. The pharmacokinetic as well as pharmacodynamic
evaluation of formulated SLNs was performed in comparison to BRE in scopolamine-induced amnesia model.
Results:
BRE-loaded SLNs were found to be significantly more effective than BRE in alleviating the neurodegeneration.
The pharmacokinetic study revealed the improved bioavailability of prepared SLNs with the potential of sustaining the drug
release in mice for an extended period of time.
Conclusion:
The results demonstrated that the SLNs may be considered a potential delivery system for taking BRE across
BBB to treat Alzheimer’s disease.
