In Vitro Evaluation of Antiemetic Topical Gels in Cancer Chemotherapy
No full textThe objective of this study was to evaluate the diffusivity and the release characteristics of different antiemetics from plurionic gels using various in vitro models (polymeric membrane, skin sheds of Yellow Rat and Com Snake). Dexamethasone, haloperidol, lorazepam, and metoclopramide were used as model drugs in the PLO gel. An accurate, simple and sensitive method using a Cl8 Luna column was developed and validated for the analysis of the aforementioned antiemetics in the solution as well as in gel formulation. The in vitro release of these drugs from the PLO gels over a period of 15 hours were 18.33±12.60%, 21.60±2.11%, 89.36±9.85%, 99.02±8.16%, respectively. The percentage of drug diffused from methanolic solution over 24 hours through skin sheds of Yellow Rat Snake were 4.15±0.46%, 1.05 ±0.6%, 0.4±0.04%, 0.35±0.3% for dexamethasone, haloperidol, lorazepam and metoclopramide respectively. It was evident from all the four drug studies, the highly aqueous soluble drug, metoclopramide, had the highest in vitro release and the lowest diffusion through the skin sheds. Dexamethasone showed a significant increase in the diffusion through skin sheds of Yellow Rat Snake compared to Com Snake. This was attributed to the differences in the lipid content, surface morphology and the thickness of the snake skin sheds. The use of limonene as a penetration enhancer with the co-solvent propylene glycol and solvent extraction of the snake skin sheds enhanced the diffusion of both dexamethasone and lorazepam. Hence the incorporation of limonene along with propylene glycol can be used to enhance the absorption of the antiemetic medications from the topical gel formulation in vivo.ProQuest Traditional Publishing Optionxvii, 114 page

Synthesis of Al and Ag nanoparticles through ultra-sonic dissociation of thermal evaporation deposited thin films for promising clinical applications as polymer nanocomposite
No full textNanoparticles (NPs) having well-defined shape, size and clean surface serve as ideal model system to investigate surface/interfacial reactions. Ag and Al NPs are receiving great interest due to their wide applications in bio-medical field, aerospace and space technology as combustible additives in propellants and hydrogen generation. Hence, in this study, we have synthesized Ag and Al NPs using an innovative approach of ultra-sonic dissociation of thin films. Phase and particle size distributions of the Ag and Al NPs have been determined by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Thin film dissociation/dissolution mechanism, hence conversion into NPs has been characterized by SEM- scanning electron microscope. EDXA & ICPMS have been performed for chemical analysis of NPs. Optical properties have been characterized by UV-Vis and PL spectroscopy. These NPs have also been investigated for their anti-bacterial activity against Escherichia coli bacteria. To the best of our knowledge, this is the first time when NPs has been synthesized by ultra-sonic dissociation of thin films. As an application, these NPs were used further for synthesis of nanocomposite polymer membranes, which show excellent activity against bio film formation
