Abstract Background Mucoadhesive polymers are applicable for improving the delivery of drug by prolonging residence time and contact dosage form with mucous membrane. Mucoadhesion may be defined as a process where polymer substance gets adhered either to biological substrate or synthetic natural macromolecule, mucus The can studied determine whether they possess some mucoadhesive properties sev...

Liposomal carriers, eminent for their potential in topical drug delivery have been chosen to help embedding of nystatin molecules in the skin layers. The objective of present study was to develop and carry out rheological investigations of nystatin liposomal gel by using optimization technology in terms of 2 factorial design. In this study attempts have been made to formulate liposomal dispersi...

Terminalia arjuna, Centella asiatica and Curcuma longa are reported to possess wound healing, anti-inflammatory, antioxidant and anti-bacterial activities. The carbopol 934 gel formulations containing different concentrations of extract of the above mentioned herbs were formulated and their wound healing activity was studied on experimentally induced open wounds in albino rats. The individual h...

Present study deals with Topical Drug Delivery system composed of polyherbals including Neem, Tulsi, Aloe and Fenugreek which are having Antifungal and Antibacterial activity in the form of gel, were formulated using gelling agent as Carbopol 934 and was compared with ointment prepared by taking same herbal drugs using emulsifying ointment base B. P. The gels and ointments were evaluated for va...

PURPOSE The objective of this work was to develop a bioadhesive topical gel of sertaconazole nitrate with the help of response-surface approach. METHODS Experiments were performed according to a 3-level factorial design to evaluate the effects of two independent variables [amount of Carbapol 934 = X1) and Sodium carboxymethylcellulose (NaCMC) = X2)] on the bioadhesive character of gel, rheolo...

Conventional ophthalmic dosage forms have lower bioavailability due to many factors like precorneal loss factor, tear dynamics, low residence time etc. Another reason for lower bioavailability is lower permeation of conventional dosage form. This research is based on formulation of liposomal suspension to increase the lipophilic cornea. This liposomal suspension was converted in to hydogel usin...

Development of transdermal system mainly focused on formulation and characterization of monolithic matrix type transdermal drug delivery system of diltiazem hydrochloride for the treatment of mild to moderate hypertension. In this study, seven formulations were prepared in different ratio of film forming polymers. Formulations TDDS1 to TDDS7 were composed of carboxy methyl cellulose, polyvinyl ...

The aim of the present study is to prepare and evaluate mucoadhesive nasal gels of venlafaxine hydrochloride. Mucoadhesive nasal gels were prepared using polymers like carbopol 934 and sodium alginate and characterized in terms of viscosity, texture profile analysis, ex vivo drug permeation profiles and histopathological studies. The results show that values of viscosity, hardness and adhesiven...

mulation of semisolid bases, generally with a significant influence on their rheological properties. When organic amines are employed as neutralizing agents of carbopols, it is possible to gel many semipolar liquids and mixtures of these liquids with water. Compatibility of the polymer and non-polar solvents depends on the formation of ion pairs with the amine. Although alcohols are useful for ...
