Objective: Buccal drug delivery is the most suited route for local as well systemic of drugs. Cilnidipine an L/N type dihydropyridine 4th generation calcium channel blocker (CCB), which decreases hypertension by blocking N-type to attenuate vascular sympathetic neurotransmission. It has high first-pass metabolism leading low bioavailability. Hence present research work was undertaken formulate ...

The present work aimed at studying the interaction between insulin and SiNP surfaced with mucoadhesive polymers (chitosan, sodium alginate or polyethylene glycol) and the evaluation of their biocompatibility with HepG2 and Caco-2 cell lines, which mimic in vivo the target of insulin-loaded nanoparticles upon oral administration. Thus, a systematic physicochemical study of the surface-modified i...

Drug actions can be improved by new drug delivery system, such as mucoadhesive system. This system remains in close contact with the absorption tissue, the mucous membrane, releasing the drug at the action site leading to improvement in both local and systemic effects. There are many routes of mucoadhesive drug delivery system, oral route is the most ancient as well as preferred by patient bein...

Mucoadhesive polymer-coated pellets containing metformin hydrochloride were prepared by the powder-layering technique using a centrifugal fluidizing (CF)-granulator. Four high-viscosity polymers were applied to make the pellets: 1) hydroxymethylcellulose (HPMC), 2) sodium alginate (Na-Alg), 3) HPMC/Carbopol, and 4) sodium carboxylmethylcellulose (Na-CMC). The physical crushing test, mucoadhesiv...

Mucoadhesive nanosuspension of ciprofloxacin was designed in order to improve the solubility, bioavailability and efficacy for the treatment of typhoid fever. The identity and purity of drug was established. The compatibility of drug with various excipients was ascertained by FTIR techniques, which indicated no interaction between the drug and excipients. Four different formulations were prepar...

The report planned to design plus valuate mucoadhesive buccal patches of Metoclopramide for orthopedic treatment pain and inflammations. All eight formulation acquire numerous evaluation parameters, it used be complete which F1 confirmed good strength, encouraging pressurized arrant drug release, easiest In-vivo residence time, swelling index pH shows the best formulation. acquired in vivo effe...

The specific aim of this work was to prepare mucoadhesive patches containing tetracycline hydrochloride and carvacrol in an attempt to develop a novel oral drug delivery system for the treatment of mouth infections. The bilayered patches were prepared using ethyl cellulose as a backing layer and carbopol 934 as a matrix mucoadhesive layer. Patches were prepared with different loading amounts of...

This paper describes formulation considerations and in vitro evaluation of an oleic acid-based polyelectrolytic polymer-containing microemulsion drug delivery system designed for intranasal administration of a hydrophobic model drug Olanzapine. Drug-loaded microemulsions were successfully prepared by a water titration method. The microemulsion containing 4% oleic acid, 30% surfactant mixture of...

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...

Till now very few formulations are available from which the drug is uniformly absorbed, so that the safe and effective blood level of norfloxacin could be maintained for a prolonged period. To fulfill this requirement, a controlled release mucoadhesive suspension was prepared by using a mucoadhesive carbopol934 polymer. The chemical interaction between norfloxacin and the polymer in formulation...
