Mucoadhesive controlled-release devices can improve the effectiveness of a drug by maintaining the drug concentration between the effective and toxic levels, inhibiting the dilution of the drug in the body fluids, and allowing targeting and localization of a drug at a specific site. Acrylic-based hydrogels have been used extensively as mucoadhesive systems. They are well suited for bioadhesion ...

Mucoadhesive polymers have been proposed as drug delivery carriers due to their ability to adhere to the mucus layer. A relatively new class of mucoadhesive polymers, termed thiomers, was suggested as an improved carrier capable of creating disulfide covalent bond with the mucus. Since the wet physiological environment is likely to cause any delivery system to adsorb water and arrive hydrated t...

PURPOSE To assess 1) patient satisfaction of a mucoadhesive biopatch with citrus essential oil and 2) the change in pain severity and the oral health-related quality of life in patients with recurrent aphthous stomatitis. PATIENTS AND METHODS Thirty-seven patients with recurrent aphthous stomatitis participated in the study. Baseline records of personal data, ulcer assessment, visual analog s...

Enalapril maleate is used in the treatment of hypertension and angina pectoris. It shows low bioavailability due to high hepatic first pass metabolism. Hence the present work was undertaken to formulate mucoadhesive buccal films of enalapril maleate with an objective to improve therapeutic efficacy, patient compliance and the bioavailability. In the present study ten formulations of mucoadhesiv...

INTRODUCTION Metronidazole is the drug of choice in the treatment of periodontal pockets up to 5 mm in depth. It is topically applied--directly into the periodontal pockets. There are no registred trademark preparations for this purpose in the market of Serbia and Montenegro. The aim of our latest research was to test the efficacy of newly formulated preparation containing 25% metronidazole sus...

buccal mucoadhesive films have attracted great attention among mucoadhesive systems due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. the aim of the current study was to formulate the ziziphus jujuba aqueous extract as buccal bioadhesive film, which continiously releases the drug at sufficient concentration for reducing the frequency of th...

background the dilution and rapid elimination of topically applied drugs due to the flushing action of saliva is a major difficulty in the effort to eradicate infections of oral cavity. utilization a proper delivery system for incorporation of drugs has a major impact on drug delivery and such a system should be formulated for prolonged drug retention in oral cavity. objectives the aim of the p...

Purpose: To develop mucoadhesive patches for buccal administration of metoprolol succinate and to evaluate their in vitro and in vivo bioadhesion. Methods: The mucoadhesive buccal patches were prepared by solvent casting technique using two different mucoadhesive polymers. The formulations were tested for in vitro drug permeation studies, buccal absorption, in vitro drug release studies, moistu...

Lorazepam a benzodiazepine drug is used as an antianxiety, sedative, hypnotic, and anticonvulsant drug. Bypassing the enterohepatic recirculation and first-pass metabolism of lorazepam by sublingual delivery of this drug may accelerate the onset of its action. The objective of this study was the formulation, optimization and in vitro characterization of mucoadhesive sublingual tablets of loraze...

Oral films, a promising novel drug delivery system, are a strip of single or multilayered, mucoadhesive or non-mucoadhesive, thin polymeric films that are intended to deliver active therapeutic moieties either locally or systemically in oral cavity through sublingual, buccal, palatal, or gastrointestinal absorption [1-3]. In general, films are known by several names including but not limited to...
