To avoid the systemic adverse effects that might occur after oral administration, transdermal delivery of ambroxol was studied as a method for maintaining proper blood levels for an extended period. Release of ambroxol according to concentration and temperature was determined, and permeation of drug through rat skin was studied using two chamber-diffusion cells. The solubility according to PEG ...

Abstract: Background: Hydrotropic solid dispersion has been reported as a potential process to improve the poor solubility of drugs using conventional hydrotropes. The presented investigation described water-soluble hydrotropic system for Meloxicam (MX) sodium benzoate hydrotrope enhance and topical delivery. Thus, was prepared, characterized, converted into HSD-Meloxicam gel. prepared gel furt...

Achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermatological products. The use of penetration enhancers could provide a successful mean for this purpose. The aim of this study was to evaluate the effect of incorporating a few common penetration enhancers (in different concentrations) into a 0.5% w/w piroxicam (model drug) gel formulation, on th...

A common problem encountered during the production of recombinant proteins, particularly in bacteria, is their tendency to accumulate in an insoluble and inactive form (i.e., as inclusion bodies). Although sometimes it is possible to convert the aggregated material into native, biologically active protein, this is a time-consuming, costly, and uncertain undertaking. Consequently, a general mean...

Abstract A total non-aqueous capillary electrophoresis method was developed and applied for the first time quantification of eugenol in cloves dental preparations. The optimized conditions included a buffer consisting 150 mM sodium acetate 300 μL 1 M acetic acid methanol solution (30 mM), an voltage 25 kV, temperature °C wavelength 214 nm. determining characterized by following parameters: dete...

   Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...

Abstract: Minoxidil, a pyrimidine derivative (2, 4-diamino-6-piperidinopyrimidine-3-oxide) is the only topical medical treatment with proven efficacy for the treatment of Androgenetic alopecia that shown low skin penetration and bioavailability. The main aim of this research was to investigate the effect of some permeation enhancers on the in vitro skin permeability of minoxidil . Minoxid...

despite extensive evidence for cognitive deficits associated with drug use and multiple publications supporting the efficacy of cognitive rehabilitation treatment (crt) services for drug addictions, there are a few well-structured tools and organized programs to improve cognitive abilities in substance users. most published studies on cognitive rehabilitation for drug dependent patients used re...
