combination dosage forms of naproxen sodium and pseudoephedrine hydrochloride are used for symptomatic treatment of cold and sinus disorders. in this study, fourth-order derivative spectrophotometric method was used for simultaneous determination of naproxen sodium and pseudoephedrine hydrochloride. the method was linear over the range of 2-28 μg/ml for pseudoephedrine hydrochloride and 4-200 μ...

two simple, accurate and precise methods for simultaneous estimation of esomeprazole and itopride in bulk drug and tablet dosage form have been described. method-a employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. method -b is absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.beer’s law was obeyed in the con...

background: interaction between local anesthetic solution, lidocaine hydrochloride (with and without adrenaline), and root canal irrigants such as sodium hypochlorite (naocl), ethylene diamine tetra-acetic acid (edta), and chlorhexidine (chx) has not been studied earlier. hence, the purpose of this in vitro study was to evaluate the chemical interaction between 2% lidocaine hydrochloride (with ...

AIM The aim of the study was to find genetic markers which can have influence on susceptibility of paranoid schizophrenia and the treatment efficiency measured by the PANSS (Positive and Negative Syndrome Scale). We analysed the gene polymorphisms: dopamine receptor--DRD2 (Taq 1A, in egzon 8,- 141 C ins/del), dopamine transporter--DAT, kainate receptor--GRIK3, serotonine transporter--SERT, sero...

the objective of the present study was to prepare controlled release formulation of moxifloxacin hydrochloride ocular nanoparticles. the nanoparticles were prepared by solvent displacement method using eudragit rl 100 as a polymer. different formulations were prepared by varying the ratios of drug and polymer and varying the ratios of organic and aqueous phase. the formulations were evaluated i...

Literature survey reveals that few analytical methods were reported for the estimation of cinacalcet hydrochloride by LC, UV methods. Hence the present study aims in developing simple, rapid, precise and validated methods for cinacalcet hydrochloride in bulk. The methods are Colorimetric determination of Cinacalcet Hydrochloride by Visible Spectrophotometric method, Validation of Cinacalcet Hyd...
