Mucoadhesive polymers have recently gained interest among pharmaceutical scientists as a means of improving drug delivery by promoting dosage form residence time and contact time with the mucous membranes. Mucoadhesion occurs between two surfaces, one of which is a mucous membrane and another is drug delivery system. Pharmaceutical aspects of mucoadhesion have been the subject of great interest...

This study aimed at designing mucoadhesive microemulsion gel to enhance the brain uptake of Ibuprofen through intranasal route. Ibuprofen loaded mucoadhesive microemulsion (MMEI) was developed by incorporating polycarbophil as mucoadhesive polymer into Capmul MCM based optimal microemulsion (MEI) and was subjected to characterization, stability, mucoadhesion and naso-ciliotoxicity study. Brain ...

BACKGROUND Dry mouth is a frequent complaint of adults worldwide. In those who experience dry mouth, therapeutic options include the use of salivary substitutes and sialogogues. METHODS The authors compared the efficacy and safety of mucoadhesive disks (OraMoist, Axiomedic, Zurich; distributed by Quantum Health, Eugene, Ore.) applied three times daily with those of placebo mucoadhesive disks ...

The medicinal Malaysian leeches have been used in traditional medicine to treat many different ailments. In this study, leech saliva extract (LSE) was collected from the medicinal Malaysian leech Hirudinaria manillensis. Gel electrophoresis of LSE was carried out to estimate the peptide and protein molecular weights of its content. Results showed that LSE contains more than 60 peptides and prot...

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) ...

The study investigated the feasibility of lyophilization for long-term preservation of somatic cells and embryonic development after whole cell intracytoplasmic injection (WCICI) into enucleated pig oocyte. Confluent cultured porcine fetal fibroblast (pFF) cells were lyophilized and stored at 4°C for at least 6 months. Results showed that compared to non-lyophilized control cells, lyophilized c...

Iodomethane reacted in vacuo with lyophilized alpha-chymotrypsin to give an inactive enzyme in which the active-site imidazole was dimethylated. However, alpha-chymotrypsin co-lyophilized with the competitive inhibitors, N-acetyl-L-tryptophan or N-acetyl-D-tryptophan, was fully protected from such inactivation. In contrast, indole by itself not only did not protect the lyophilized enzyme from i...

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 ...
