BACKGROUND Targeted drug delivery to colon would ensure direct treatment at the disease site, decrease in dose administration and reduction side effects improved drug utilization. OBJECTIVE The purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. MATERIALS AND METHODS Ionotropic gelation wa...

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...

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 aim of the present work was to formulate and evaluate betahistine-loaded chitosan microspheres intended for nasal delivery with focus on their mucoadhesive properties. Betahistine-loaded chitosan microspheres were obtained via W/O emulsion solvent evaporation technique and were characterized for particle size, surphace morfology and entrapment efficiency. FTIR spectroscopy was carried out t...

The study was aimed to design and evaluate a new effervescent mucoadhesive vaginal drug delivery system for ciclopirox olamine (CPO), a broad-spectrum antifungal, antibacterial, and anti-inflammatory agent for effective treatment in vaginal candidiosis. Various polymers like Polyox 303, Carbopol 974P, HPMC K4M, Sodium CMC, HPC, Sodium Alginate, Xanthan Gum, Polycarbophil and Chitosan were used ...

ORIGINAL RESEARCH ARTICLE ABSTRACT Background: Carbamazepine (CBZ) is an antiepileptic orally administered drug, but due to its low solubility in water, its gastrointestinal absorption is slow and irregular, leading to delay brain uptake with consequent peripheral side actions. The main objective of this study was to assess mucoadhesive CBZ-loaded o/w nanoemulgel (MNEG) as a nasal delivery syst...

The purpose of current article focuses on polymers used in mucoadhesive drug delivery system. The term “mucoadhesive” is defined as the “attachment of drug elongated with asuitable carrier like natural or synthetic polymer to mucus and/or an epithelial surface”. It is a popular novel drug delivery system because relatively permeable of mucous membranes, and mucus have higher blood flow therefor...

Administered by an oral route, Furosemide (FUR), a diuretic used in several edematous states and hypertension, presents bioavailability problems, reported as a consequence of an erratic gastrointestinal absorption due to various existing polymorphic forms and low and pH-dependent solubility. A mucoadhesive sublingual fast-dissolving FUR based film has been developed and evaluated in order to op...

Aim: Mucoadhesive buccal films provide drug delivery for both local and systemic circulation with increased patient compliance. The objective of this study was to develop a film containing benzydamine hydrochloride (BNZ) by using hyaluronic acid (HA) as film-forming agent glycerin (Gly) plasticizer the anti-inflammatory effect on mucosal ulcer. Material Methods: effects different concentrations...

conclusions algino-pectinate mucoadhesive formulations exhibited promising properties of a sustained release form for piroxicam and provided distinct tissue protection in stomach. objective the purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. materials and methods ionotropic gelation was us...
