The current study involves the fabrication of oral bioadhesive bilayer matrices of narrow absorption window drug baclofen and the optimisation of their in vitro drug release and characterisation. Statistical design of experiments, a computer-aided optimisation technique, was used to identify critical factors, their interactions and ideal process conditions that accomplish the targeted response(...

The aim of the present work was to assess the feasibility of Acconon MC8-2 EP/NF as a bioadhesive material for developing controlled release gastroretentive microsponges of loratadine. Modified emulsion-solvent diffusion method was employed for the preparation of microsponges (F1-F9) based on  32 factorial design. The amount of ethyl cellulose (EC) and polyvinyl alcohol (PVA) were selected...

There is a requirement for the development of oral dosage forms that are adhesive and allow extended oesophageal residence time for localised therapies, or are non-adhesive for ease of swallowing. This study provides an initial assessment of the in vitro oesophageal retention characteristics of several widely utilised pharmaceutical coating materials. To this end, a previously described apparat...

Present research is about the In-situ gels for site specific delivery. In the present work, formulations with chitosan, bioadhesive and permeation enhancer and gellan gum ion activable gelling polymer and temperature sensitive polymeric systems was used for In-situ geliling. The developed formulations was characterized for various in-vitro parameters e.g. clarity, pH, isotonicity, viscosity, dr...

PURPOSE 5-Methoxy-carbonylamino-N-acetyltryptamine (5-MCA-NAT, a melatonin receptor agonist) produces a clear intraocular pressure (IOP) reduction in New Zealand White rabbits and glaucomatous monkeys. The goal of this study was to evaluate whether the hypotensive effect of 5-MCA-NAT was enhanced by the presence of cellulose derivatives, some of them with bioadhesive properties, as well as to d...

The aim of this study was to investigate the effect of benzydamine hydrochloride bioadhesive gel on healing of oral mucosal ulceration in an animal model. For in vivo determination of the effects of the bioadhesive gel, 36 rabbits were separated into three groups: the first group was treated with the gel formulation without active agent, the second group with the gel formulation containing benz...

In this study, a bioadhesive dosage form of clotrimazole was designed using a combination of bioadhesive polymers Carbopol 934P, sodium carboxymethyl cellulose and sodium alginate in different ratios. The bioadhesive strength was evaluated by measuring the force required to detach the tablets from porcine vaginal mucosal membrane. The strong interaction between polymer and mucus lining of the t...
