The adhesive properties of certain types of biopolymer can be used to increase the residence time of orally or nasally administered drugs. A fuller understanding of the molecular processes underpinning such 'mucoadhesive' phenomena will help in the optimal design of delivery systems. The interactions involved are, however, less well defined compared with those often encountered in protein-recog...

The goal of the present investigation was to design and evaluate mucoadhesive buccal patches of Ondansetron Hydrochloride (OND) which is used for nausea and vomiting associated with cancer chemotherapy and radiotherapy. Permeation of OND was calculated ex vivo using porcine buccal membrane. Buccal films were developed by solvent-casting technique using Hydroxy Propyl Methyl Cellulose(HPMC E15) ...

Purpose: To formulate Eudragit RS 100-based nanoparticles containing metronidazole (MTZ NPs) and incorporate them into hydrogels using different gelling agents for controlled release in the buccal mucosa.
 Method: MTZ NPs were fabricated nanoprecipitation method. (1 % w/w) introduced excipients. Physicochemical properties of NPs, mucoadhesive strength spreadability hydrogels, ex vivo perme...

In the present study, thiol-functionalization of tamarind seed polysaccharide was carried out by esterification with thioglycolic acid. Thiol-functionalization was confirmed by SH stretch in Fourier-transformed infra-red spectra at 2586 cm(-1). It was found to possess 104.5 mM of thiol groups per gram. The results of differential scanning calorimetry and X-ray diffraction study indicate increas...

The objective of the present investigation was to develop and evaluate microemulsion based gel for the vaginal delivery of Sertaconazole. The solubility of Sertaconazole in various oils, surfactants and co-surfactants were checked to identify components of the microemulsion. The ternary diagrams were plotted to identify the area of microemulsion existence. Various gelling agents were evaluated ...

Objective: The objectives of the present work were to carry out thiol-modification (i.e., thiolation) fenugreek polysaccharide (FP) and assess synthesized thiolated product (TFP) as a mucoadhesive excipient in designing formulations (metronidazole gels metronidazole buccal discs). Methods: Extracted CG was thiol-modified via an esterification reaction by utilizing thioglycolic acid with acidic ...

The present study deals with the formulation, characterization of Metronidazole loaded ethosomal gel for treating oral infection. system comprises 2-5% phospholipids, 20-50% ethanol, 10% propylene glycol, cholesterol and v/v aqueous phase. Cold method was applied to develop ethosome. prepared ethosome evaluated vesicle size, entrapment efficiency,The Optimized Ethosome formulation converted in ...

Buccal delivery involves the administration of the desired drug through the buccal mucosal membrane lining of the oral cavity.The objective of this article is to review buccal drug delivery by discussing the structure and environment of the oral mucosa and highlighting the mechanisms of drug permeation and methodology in evaluating buccal formulations. This review also highlights a brief descri...

Domperidone microspheres for intranasal administration were prepared by emulsification crosslinking technique. Starch a biodegradable polymer was used in preparation of microspheres using epichlorhydrine as cross-linking agent. The formulation variables were drug concentration and polymer concentration and batch of drug free microsphere was prepared for comparisons. All the formulations were ev...

The delayed release and mucoadhesive properties of Cedrela gum and hydroxypropylmethylcellulose blend in diclofenac sodium tablet formulations were evaluated. Tablets were prepared by direct compression and the crushing strength and detachment force were found to increase from 74.49 ± 1.22 to 147.25 ± 2.57 N and 0.302 ± 0.36 to 1.141 ± 0.05 N from low to high level of polymers, respectively.
