Abstract
A thin film refers to a pliable polymer layer, with or without a plasticizer, that has been observed to enhance the onset of medicine action, reduce dosing frequency, and enhance the efficacy of drugs. One such technique involves the utilization of polyelectrolyte complexes (PEC) in the preparation of films. This work concerned with studying variables affecting the preparation of topical film for penciclovir using PEC of chitosan and acacia. In this study, Skin bioadhesive polymeric films were fabricated using a solvent casting approach, using acacia gum and chitosan as the main components. The resulting films were further examined to evaluate their features and drug relea

Pharmaceutically speaking, OLM is a class II medication (low solubility, high permeability) that is practically insoluble.Due to its extremely poor solubility, which negatively affects its usefulness, oral medication have a low (26%) bioavailability. The current strategy involves generating OLM as a micellar dispersion in the nano range scale utilizing the film hydration process. In order to prepare transparent aqueous formulations, increase drug solubilization, and administer medication orally, Soluplus (SLP) was employed as a micellar nanocarrier.Different SLP concentrations were used to make eight formula

Some of these drugs are used for the treatment of acute attacks; while others are effective as prophylactic measures to decrease the duration and frequency of attacks. Pizotifen, a 5-HTA antagonist, is one of the prophylactic drugs for which the clinical use resulted in low outcomes in reducing migraine symptoms. Melatonin, a serotonin derived neurohormone, was reported to exert many functions like sleep induction, anti-inflammatory, neurovascular regulation, cytoprotection and modulation of neurotransmitter release. In the view of the involvement of serotonin in the pathophysiology of migraine a

Mucosal ulcers associated with the onset of ulcer are manifested by an increase in proinflammatory cytokine, excessive prostaglandin, and up-regulation of Endothilin-1 level, which directly impacts the release of leptin. These, released locally within mucosal tissues, have played a role in controlling the extent of local inflammatory responses and processes of mucosal repair.
This study was designed to find out the correlation of plasma leptin and prostaglandin levels as a possible mechanism of oral ulcer formation as an adverse effect of nicorandil. The effect of nicorandi

Show MoreThe survival of dried spores of A.flavus, Penicillia Spp., and Cladosporia Spp.inoculated into multivitamins and folic acid tablets were examined at different compression pressures.Survival of fungal spores decreased with increasing compression pressure. The level of survival at particular pressures was shown to depend on the size of the contaminating fungal spores.The lethal effect of tabletting was attributed to shearing forces upon the contaminating spores generated by interparticulate movement. This hypothesis was supported by the dependence of survival upon spore size.

Chronic kidney disease patients undergoing hemodialysis are frequently suffering from uremic pruritus, which can be quite uncomfortable. Uremic pruritus affects over 40% of hemodialysis patients. Bile acids have been implicated in the pathogenesis of pruritus; especially in conditions associated with cholestasis. The purpose of the study is to investigate the serum levels of total bile acids in chronic kidney disease patients on hemodialysis, with and without uremic pruritus. Ninety adults, chronic kidney disease patients who were on chronic hemodialysis at the hemodialysis unit at Al-Fallujah Teaching Hospital in Fallujah City, Iraq, were involved.
