The objective of this study was to develop and evaluate lacidipine (LD) loaded solid lipid nanoparticles (LD-SLNs) for improving the oral bioavailability. LD-SLNs were prepared in two steps. First step was hot homogenization and next by ultrasonication method, using triglycerides (tripalmitin and tristearin), monoglyceride and surfactants (Poloxamer 188 and egg lecithin E80). The prepared LD-SLNs were characterized for particle size, PDI, zeta potential, drug content, entrapment efficiency (EE %).         In vitro drug release studies using a dialysis bag method in 0.1N HCl and pH 6.8 phosphate buffer were conducted. In addition, long-term physical stability of the optimized SLNs was investigated at refrigerated and room temperature for 60 days. FTIR and DSC studies revealed that no interaction between the drug and lipids. LD-SLNs prepared with Dynasan-116 (F3), having the size of 141.86nm, PDI of 0.293, ZP of -22.3 m with 94.75% of EE was optimized and was stable for 60days. Scanning electron microscopic studies showed nearly spherical shaped particles. Further, pharmacokinetic studies were conducted in wistar rats. The relative bioavailability of LD in SLNs was 2.03 times when compared with that of the LD suspension. The results are indicative of SLNs as suitable lipid based carrier system for improving the oral bioavailability of LD.

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.
