Aim: Topical drug delivery of fluconazole, an antifungal drug, in gel form was formulated to avoid the side effect of the oral route. Methodology: Different polymers; Sodium carboxymethyl cellulose, Sodium alginate, Carbopol 934P, Hydroxypropylmethyl cellulose, Pluronic F-127 and hydroxypropyl cellulose, were used. The compatibility of fluconazole and different gelling polymer was assessed thro...

Graft copolymer networks of poly(methacrylic acid-g-ethylene glycol) were prepared by free radical solution UV-polymerization of methacrylic acid (MAA) and poly(ethylene glycol) monomethacrylate. Dynamic swelling studies indicated that complexation/decomplexation processes occurred due to hydrogen bonding between the carboxylic groups of the poly(methacrylic acid) (PMAA) and the ether groups of...

Article history: Received on: 09/10/2014 Revised on: 27/10/2014 Accepted on: 18/11/2014 Available online: 29/12/2014 The objective of present study was to formulate hydrogel thickened Lornoxicam transdermal formulation. Eutectic mixture of camphor and menthol was chosen as oily phase (maximum 10%), solvent for Lornoxicam and powerful penetration enhancer. Tween 80, ethanol and Carbopol 934p, HP...

Mucoadhesive microbeads of low methoxyl pectin were prepared, either alone or in combinations with hydroxypropyl methyl cellulose, sodium carboxymethyl cellulose, methyl cellulose and carbopol 934P, by ionotropic gelation. The influence of copolymers on mucoadhesivity, microbeads characteristics and in vitro drug release was investigated. Spherical microbeads with 78.69±0.59 to 85.84±0.78% drug...

The present study describes the preparation and evaluation of a poloxamer 407 (P407)-based thermoreversible gel using Carbopol 934P (C934P) as a mucoadhesive polymer and hydroxypropyl-β-cyclodextrin (HP-β-CD) for enhancing the aqueous solubility and intranasal absorption of fexofenadine hydrochloride (FXD HCl). The prepared gels were characterized by gelation temperature, viscoelasticity, and d...

The purpose of the present study was to develop an optimized gastric floating drug delivery system (GFDDS) containing domperidone as a model drug. Box-Behnken design was employed in formulating the GFDDS with three polymers: hydroxypropyl methylcellulose K4M (HPMC K4M) (X1), Carbopol 934P (X2) and sodium alginate (X3), as independent variables. Floating lag time (FLT), total floating time (TFT)...

Floating drug delivery systems (FDDS) are utilized to target discharge in the stomach or upper parts of intestine. Famotidine has been most extensively used for management peptic ulcer various decades. The current study concerns development and evaluation floating tablets famotidine which, after oral administration, planned extend gastric residence time, enhance bioavailability aim ulcer. A FDD...

Abstract: Objectives: The ambition of this study is to find the mucoadhesive assets Pistacia lentiscus plant gum (mastic gum) by combining it into microspheres with Amoxicillin Trihydrate (ATH). Significance: Due its short stomach residence duration, ATH efficient against H. pylori but can be improved creating Mucoadhesive Microspheres (MMS) that keep trihydrate in stomach. In study, has been e...

The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. Propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934P as mucoadhesive polymer and ethyl cellulose as carrier ...

       Gel dosage forms are successfully used as drug delivery systems considering their ability to control drug release and to protect medicaments from a hostile environment. The aim of this work was to investigate the properties of carbopol 934P polymeric system in water-misible cosolvents such as glycerin and alcohol. Benzocaine is a local anesthetic and the mucosal gel formulation is appl...
