Mucuna Pruriens Seeds Extract Loaded Phytosomal Intranasal Gel for the Effective Treatment of Parkinson’s Disease

Drugs of origin from nature are significant and vital components of contemporary medicine.as they are occurring in nature, herbal remedies have fewer adverse consequences, which is why many traditional medical practitioners and scientists utilize them to treat conditions including diabetes, cancer, rheumatoid arthritis, inflammation, and several more [1][2] .These products are made to provide specific medical advantages using different ways to deliver drugs (DDS).According to reports, these unique drugs delivery methods provide remarkable benefits over traditional formulations of plant extracts or active ingredients.Improvements in solubility, bioavailability, toxicity, pharmacological activity, stability, tissue distribution, prolonged administration, and protection against physical/ chemical deterioration are some of the factors that may be considered. 3 Phytosome for herbal drug deliveryThe reaction between phosphatidylcholine and phospholipids results in lipid-compatible molecular complexes known as phytosome, which are complexes of phospholipids and naturally occurring potent phytochemicals that are bound in their structures. [4][5]5] It mostly consists of the lipidbound, bioactive phytoconstituents of the herb.Polar or water-soluble substances constitute most organisms' physiologically active components.However, water-soluble phytoconstituents (such as flavonoids, tannins, glycosidic aglycones, etc.) have poor absorption because of their large molecular size, which hinders passive diffusion, or because they are poorly soluble in lipids, which greatly limits their ability to cross lipid-rich biological membranes, resulting poor bioavailability 5,6,7,8 Mechanism of Nose-to-Brain Drug DeliveryThe nasal mucosa has emerged as a useful site targeting tissue for drug delivery resulting from its accessibility, high blood flow, large surface area, porous endothelial membrane, and ability to avoid hepatic first-pass metabolism. 9The transport has been reported to involve the combination of the biofluids from the vasculature and lymphatic system to be responsible for the transport of bioactive agents from the nasal cavity to the brain.Iintranasal delivery is an alternative administration route for levodopa (L-Dopa) to the brain.It offers high drug permeability across the nasal epithelium and rapid absorption into the central nervous system (CNS) while bypassing first-pass metabolism. 10 Parkinson's disease and its treatmentParkinson's disease is a brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination.Symptoms usually begin gradually and worsen over time.As the disease progresses, people may have difficulty walking and talking.They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue.Mucuna pruriens is a species of bean that grows in the tropics.It is very rich in natural L-Dopa.Mucuna seed extract has been an effective treatment of ABSTRACT One phytoconstituent derived from Mucuna pruriens (legumes) is levodopa.This medication's oral usage is limited by its high first-pass metabolism and low absorption.The goal of the present research was to develop a phytosomal gel filled with levodopa extract for better delivery and brain targeting.Various techniques, including solvent evaporation, salting out anti-solvent precipitation, direct egg yolk, and egg lipids methods, were used to create phytosomal formulations.Scanning electron microscopy, particle size, x-ray diffraction, and other techniques were used to characterize phytosomes.And added into gel formation, the more successful batch was examined for several parameters.The final batch underwent a variety of animal tests, including pharmacokinetic analysis, irritation to the nasal cavity testing.The most effective phytosomes were those made via the antisolvent precipitation approach.In this investigation, a 3 2 -randomized complete factorial design was employed.Batch F4 had an entrapment efficiency of 70%, a particle size of 15 (g) and 60% CDR.The gel-formulated batch F4G3 demonstrated improved results in terms of extrudability (90.82), amount of drug (89.32%),viscosity (5421 cps at 100 rpm), and spreadability (25.18).Batch F4G3 of the Mucuna pruriens phytosome gel exhibited Higuchi's kinetics.According to the findings of the animal study, dopamine levels were significantly elevated.The pharmacokinetic and nasal irritation studies showed notable in vitro penetration of the nasal mucosa without resulting in skin irritation.For improving Parkinson's disease treatment, the phytosomal gel formulation delivered via the nasal route would be the ideal option.
