The purpose of this research was to isolate the smart biopolymer from the fruit pulp of Fragaria × ananassa (garden strawberry). We isolated natural fruit pulp to evaluate the potentiality of biopolymer in delivery of nanosized lamotrigine as an antiepileptic drug. Lamotrigine was nanosized by screening its nano-size particle by UV method. The nanosized lamotrigine was used for preparation of bionanoparticles (LF1-LF8) by sonication method. The isolated biopolymer was characterized for DSC, FTIR, NMR, Mass and Zeta particle size analysis. The obtained results confirm its polymeric nature in different analysis. The prepared bionanoparticles showed the release of lamotrigine in sustained manner over 36 hours. The release kinetic study was done by using the BIT-SOFT 1.12 software and T50% and T80%, r2 were calculated. All the formulation showed more than 99.78% drug release. The In-vitro release study of different formulations showed the % drug release from 90.92% to 99.78%. The different formulations were evaluated for the In-vitro release study and release kinetic was studied. The formulation LF5 was found to be the best formulation having T50% of 17 hours and T80% of 29 hours with r2 value of 0.9925. The best formulation LF5 showed up to 90.925% drug release over 36 hours. According to the release kinetic study, the best-fit model was found to be Koresmayer-Peppas and the mechanism of drug release was found to be anomalous transport. The results obtained from different evaluations like percentage entrapment efficiency, particle size, release study, kinetic studies and stability study revealed that isolated biopolymer has good potentiality to form bionanoparticles and it can be safely used as an alternative to synthetic and semisynthetic polymers for the preparation of lamotrigine loaded stable bionanoparticles

The aim of this research was to synthesize and characterize chitosan-calcium alginate as matrix isoniazid encapsulation to produce controlled release isoniazid drug. The microparticles were evaluated for surface morphology, functional groups, size particles, drug content and swelling index. The drug release kinetic was investigated at gastric and intestinal artificial pH. The results showed that isoniazid-calcium alginate-chitosan has majority particle diameter of 1001-1500 nm. The release mechanism of isoniazid was through combination of erosion and diffusion.

Background: : Epilepsy is a genuine neurological turmoil that effects around 50 million individuals around the world. Practically 30% of epileptic patients experience the ill effects of pharmaco-obstruction, which is related with social seclusion, subordinate conduct, low marriage rates, joblessness, mental issues and diminished personal satisfaction. At present accessible antiepileptic drugs have a restricted viability, and their negative properties limit their utilization and cause challenges in patient administration. Gabapentin 1-(aminomethyl)cyclohexane acetic acid, Gbp , (trade name Neurontin), a structural analog of γ-aminobutyric acid (GABA), BCS class 3 drug with having permeability issues. Objective: This work was an attempt to formulate and characterize a new approach to treat epilepsy by targeting to Phospholipase A2 Enzyme through Nanostructured Lipid Carrier. Methods: Docking studied carried out using Accelrys Discovery studio 4.1 Client and gabapentin and phosphotidylcholine were conjugated through chemical conjugation. Nanostructured lipid carrier (NLC) was prepared using hot homogenization technique. Results: The libdock score of Gabapentin- Phosphotidylcholine conjugate (192.535) were found to be more than Gabapentin (77.1084) and Phosphotidylcholine (150.212). For the optimized formulation the particle size (50.08), zeta potential (-1.48), PDI (0.472) and entrapment efficiency (77.8) was observed. The NLC was studies for in-vitro drug release studies and release kinetics. Finally found that the drug release from the NLC followed Higuchi release kinetic and the mode of drug release from the NLC was found to be Non- Fickian diffusion. Conclusion: The formulated Nanostructured lipid carrier of Gabapentin-Phosphotidylcholine conjugate may be able to use to prevent seizure.
