The purpose of this work was to study the effect of various permeation enhancers on the permeation of salbutamol sulphate (SS) buccal patches through buccal mucosa in order to improve the bioavailability by avoiding the first pass metabolism in the liver and possibly in the gut wall and also achieve a better therapeutic effect. The influence of various permeation enhancers, such as dimethyl sul...

    Topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. The new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. The adhesive capacity of hydroxypropyl methylcellulose (HPMC) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling test...

The objective of the paper is to study the effect of a permeation enhancer, sodium taurocholate on permeation of Ondansetron HCl from bioadhesive buccal tablet formulation by performing ex-vivo permeation experiments using porcine buccal mucosa. Optimized formulation has selected based on in-vitro drug release studies of bilayered bioadhesive buccal tablets. To the optimized formulation, 10mM s...

In the study we formulated the serratiopeptidase loaded cholic acid conjugated and unconjugated chitosan mucoadhesive microspheres. It was observed that the conjugated microspheres show better permeation rate than unconjugated microspheres. Moreover the permeation enhancer increased the % cumulative drug permeation through the mucosal membrane from 69.37 % to 74.39 % for unconjugated microspher...

Abstract: The objective of this study was to fabricate topical formulations of diclofenac diethylamine (DD) using isopropyl myristate (IPM) and isopropyl palmitate (IPP) as permeation enhancers. Franz cell and bacterial cellulose were used as analytical instrument and diffusion membrane, respectively. Permeation enhancers exhibited significant effect on the permeation characteristics of DD. It ...

The treatment of onychomycosis is a challenging task because of unique barrier properties of the nail plate which hampers the passage of antifungal drugs in a concentration required to eradicate the deeply seated causative fungi in the nail bed. In present investigation, application of hydroxypropyl-β-cyclodextrin (HP-β-CD) was established as an effective and nail friendly transungual drug perm...

OBJECTIVE(S) Drug delivery through the skin can transfer therapeutic levels of drugs for pharmacological effects. Analgesics such as NSAIDs have gastrointestinal side effects and topical dosage forms of these drugs are mainly preferred, especially for local pains. Meloxicam is one of NSAIDs with no topical form in the market. In this research, we attempted to quantify the skin permeation of a m...

Evaluated in this study were the effects of the two parameters, namely level of penetration enhancer and drug loading dose, on in vitro skin release of Caffeine and vitamin B5 and adhesion properties of drug in adhesive transdermal systems. In order to characterize in vitro drug release, a hydrodynamically Chien permeation system with rat abdominal skin was employed. Caffeine skin release rate ...

many properties of chemicals depend on their streochemistry. among these, the effects of streoisomerism on percutaneous absorption of drugs, which is subject of the present investigation, is not well studied yet. in this study, tretinoin (tt) and isotretinoin (itt) (geometric isomers) were chosen and their permeations (alone or in the presence of each other) through enhancer-treated excised rat...
