Objective: The purpose of this study was to develop and evaluate methotrexate-loaded nanoemulgel for topical delivery in the management of rheumatoid arthritis. Methods: Based on nanoemulsion composition, the pseudo ternary phase diagram was fabricated by using peanut oil, Tween 20 as the surfactant, and PEG 400 being used as a co-surfactant. The methotrexate-loaded nanoemulsion was formulated by using the spontaneous emulsification method. Badam gum was used as a gel matrix in the prepared nanoemulsion to form nanoemulgel. The methotrexate loaded nanoemulgel was characterized and evaluated for pH, particle size, physical appearance, viscosity, spreadability, TEM, drug content, diffusion study, release kinetics, and stability studies. Results: The nanoemulgel constituting 8.6% peanut oil, 34.4% of Tween 20 and PEG 400 as Smix (surfactant and co-surfactant mixture), 43% water, and 12.5% w/w badam gum was concluded as optimized formulation. The prepared nanoemulgel was translucent in nature having a particle size of 195.1nm and zeta potential of -0.278mV. Drug content and drug release for the optimized formulation were found to be 98.11±0.34% and 95.11±0.02% respectively. pH, viscosity, and spreadability were found to be optimum. Stability study data showed that the prepared nanoemulgel was stable at different temperatures varying from -25 to +45ºC. Conclusion: Methotrexate loaded nanoemulgel has been formulated for topical drug delivery for the management of rheumatoid arthritis.
Objective: The study aimed to develop and evaluate an orally disintegrating tablet that contains pilocarpine and 2-hydroxy propyl β-cyclodextrin as an inclusion complex that is prepared by lyophilization used for treatment for dry mouth. Pilocarpine is utilized to treat dry mouth disorder. The inclusion complex lowers the taste of pilocarpine through the oral mucosa by the use of 2-hydroxy propyl β-cyclodextrin. Methods: The in vitro release from the insertion complex is also been studied. The parameters like differential scanning calorimetry (DSC), Fourier transformer infrared spectroscopy (FTIR), X-ray diffraction (XRD), and morphological study have been evaluated. The design of an experiment is carried out based on the concentration of croscarmellose sodium (CCS) and microcrystalline cellulose (MCC). Evaluation of the prepared orally disintegrating tablets have been carried out by different test methods like weight variation, thickness, drug content, disintegration, and in vitro dissolution study. Results: Orally disintegrating tablets are studied by utilizing the immediate pressure technique. Pilocarpine indicates the anhydrous crystalline medication, displaying sharp endothermic top at 120.2 °C, bend of 2-HPβCD demonstrates an exceptionally wide endothermal wonder among 55-100 °C for DSC. In pilocarpine spectra, characteristic band of aromatic C-H stretch at 3277 cm-1, C=C stretching at 1608 cm-1, C-N stretching at 1445 cm-1 and methoxy (CH3-O-) stretch at 2921 cm-1 was observed. The investigation shows that tablet hardness of 4.3N, breaking downtime of 12 sec and mean disintegration time is 1.562 min. Conclusion: The different diluents and super disintegrating have been applied for the quick elevation of dry mouth that helps us for patient compliance.
Objective: The main aim of this study was to develop and evaluate the nanofiber loaded with coconut oil and silver nanoparticles (Ag NPs) for the treatment of wound healing by the electrospun method. Methods: The nanofibers have been created using the reduced form of silver nanoparticles and coconut oil along with Eudragit L-100 by the electrospun method. The presence of coconut oil and chemical interaction was determined by the FTIR method. XRD was made to evaluate the crystalline nature of AgNPs and Eudragit L-100. TEM was carried out to show the presence of AgNPs on the surface of nanofibers and SEM represents the diameter of the fiber. The antibacterial activity of nanofibers was carried out using a disk diffusion assay. Results: The diameter of the fibers was diminished by the excess of AgNPs in the fibers, while it increases by the coconut oil concentration, enhancing the nanofiber's hydrophilicity. FTIR spectroscopy was found in the range of coconut oil at 3553 cm-1for O-H stretch, 1365 cm-1, and 1240 cm-1 for the C-O stretch of ester groups. The diffraction peaks at 2θ of 38.5°, 44.6°, and 64.7°, in the XRD spectra of nanofiber, changed with silver NP affirming the total decrease of Ag salt. The bactericidal activity has been carried out between Escherichia coli and Staphylococcus aureus showing zones of inhibition of 20.0±0.2 mm and 14.8±0.4 mm, exhibiting excellent bactericidal characteristics for wound healing. Conclusion: The formulated nanofibers were obtained to offer protection against external agents and help in the regeneration of new tissue.
