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...

Conventional extraction (CE) and microwave-assisted (MAE) were compared in terms of efficiency quality pectin two separate processes aimed to extract from Malus domestica ‘F?lticeni’ apple pomace. A similar yield a shorter time was observed for the procedure as CE, while galacturonic acid content degree esterification both methods. Apple extracted this plant source by methods had high content, ...

in this study, the effects of various hydrophilic (hpmc and carbopol 971) and plastic (ethylcellulose and eudragit rl100) polymers on the release profile of diltiazem hcl from matrix tablets were evaluated in-vitro. for this purpose, tablets containing 60 mg of diltiazem hcl along with various amounts of the aforementioned polymers were prepared using the wet granulation technique. tablets prep...

background the goal of the present study was the preparation and evaluation of griseofulvin topical gel as a drug dosage form with appropriate efficacy and stability. material and methods to select the best formulation, formulations with different concentration of carbomer and hpmc were evaluated for their appearance. then evaluated for physicochemical characteristics such as rheologic behavior...

Introduction: Anal fissures are small tears in the lining skin of the anus presenting with typical symptoms of pain and bleeding during defecation. Several new forms of medicines such as glyceryle trinitrate (GTN) ointments and diltiazem, a calcium channel-blocking agent, have been recently used for the treatment of these fissures. Diltiazem relaxes the muscle of anal sphincter and consequently...

The aim of the present study was to formulate and evaluate nystatin containing thermosensitive mucoadhesive gel for vaginal drug delivery to achieve prolonging the residence time, sustained drug release, enhancing efficacy, decreasing recurrence, and increasing patient compliance in the treatment for vaginal candidiasis. Here nystatin (1%) as a model drug. A 3 full factorial design was employed...

In order to formulate an efficient and durable mucoadhesive drug delivery system, careful consideration of formulation-related parameters is critical. This study was conducted to investigate the effect of the presence of various types and concentrations of surfactants within or outside Carbopol 934 (C934) as well as hydroxypropylmethyl cellulose (HPMC) solid compacts, on their duration of mucoa...
