The conventional oral dosage forms have regarding the short duration of delivery to system. A controlled release system designed to increase its residence time in stomach with contact with mucosa was achieved by the formulation of mucoadhesive microsphere of the drug. The aim of the present study is to provide an overview of various aspects of mucoadhesive microsp various polymers, preparation ...

Drug delivery via buccal mucosa by means of buccoadhesive formulations offer distinct advantages over peroral administration. Recently, plant gums and exudates have been screened for their use as pharmaceutical adjuvants. The aim of this study is to evaluate matrix tablets containing Plantago psyllium seed mucilage in addition to carbopol as a mucoadhesive agent, and propranolol hydrochloride a...

The two major problems in the development of new drugs are low aqueous solubility and oral bioavailability. Although, drug delivery via route is most preferred for years but it also has some drawbacks. Various techniques improving have been developed, however success these depends on physical chemical properties under development. In recent years, mucoadhesive gained high popularity comparison ...

Mucoadhesion is a field of current interest in the design of drug delivery systems. Mucoadhesion is commonly defined as the adhesion between two materials, at least one of which is a mucosal surface. Mucoadhesive drug delivery system may be designed to enable prolonged residence time of the dosage form at the site of application or absorption and facilitate an intimate contact of the dosage for...

OBJECTIVE S Mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease. MATERIALS AND METHODS Every discs containing 70 mg stem bark extract of Ziziphus jujuba were formulated by using Carbopol 934, PVP k30 and gelatin as polymers. Discs were made by granulation and direct compression. Discs were standardized based on the total phenol. Properties such as in vitr...

The purpose of present investigation was to develop and optimize bucco mucoadhesive bilayered tablets of Propranolol hydrochloride (PrHCL) using the bioadhesive polymers hydroxyl propyl methyl cellulose (HPMC K4M), xanthan gum (XG) and acrypol 934P (AL-P) individually and in combination along with ethyl cellulose (EC) as an impermeable backing layer. The 3 full factorial design was employed by ...

A mucoadhesive drug delivery system for systemic delivery of nitrendipine, a calcium channel blocker through buccal route was formulated. Mucoadhesive polymers like hydroxypropylmethylcellulose K-100, hydroxypropylcellulose, sodium carboxymethylcellulose, sodium alginate, polyvinyl alcohol, polyvinyl pyrrolidone K-30 and carbopol-934P were used for film fabrication. The films were evaluated for...

The purpose of this research was to formulate and systemically evaluate in vitro and in vivo performances of mucoadhesive amoxicillin microspheres for the potential use in the treatment of gastric and duodenal ulcers, which were associated with Helicobacter pylori. Amoxicillin mucoadhesive microspheres containing carbopol-934P as mucoadhesive polymer and ethyl cellulose as carrier polymer were ...

OBJECTIVE Betahistine dihydrochloride (BH.2HCl), an anti-vertigo histamine analog used in the treatment of Ménière's disease, undergoes extensive first-pass metabolism and suffers from short biological half-life. The aim of the present work was to develop and estimate controlled release mucoadhesive buccal tablets of BH.2HCl with a unidirectional drug flow to overcome this encumbrance. METHOD...

Of the various routes of drug delivery, the oral route is often preferred by the patient. However, peroral administration of drugs has disadvantages such as hepatic first-pass metabolism and enzymatic degradation within the gastrointestinal tract which constitutes a hindrance to oral administration of certain classes of drugs, especially peptides and proteins. Consequently, other absorptive muc...
