Warfarin merupakan turunan sintetik kumarin yang penggunaannya sebagai antikoagulan oral biasa digunakan untuk mencegah dan mengobati penggumpalan darah, profilaksis pengobatan emboli paru trombosis vena, komplikasi tromboemboli dari fibrilasi atrium atau penggantian katup jantung, serta risiko kematian infark miokard berulang, kejadian setelah dapat di kurangi. indeks terapi sempit apabila ada...
Deproteinisation with acetonitrile (along with methanol or other reagents) is a useful and rapid technique in analysis of drugs or their metabolites in human serum. In this paper application of this simple technique in biopharmaceutical analysis using capillary electrophoresis (CE) is evaluated. Some drugs with different ionic and protein binding properties were selected and dissolved in human ...

The suitability of micellar electrokinetic chromatography for the simultaneous trace determination of several compounds (sulfamethoxazole, trimethoprim, sulfanilic acid, sulfanilamide, 3,4,5-trimethoxybenzoic acid and nonoxynol-9) was assessed. The mixture was separated within 14min at an applied voltage of 22kV by using 30mM phosphate electrolyte, containing 10mM SDS, adjusted to pH 7.8. Under...
Degradation of extracellular matrix components is central to many pathological features of chronic destructive lung disorders. Desmosine and isodesmosine are elastin-derived cross-linked amino acids whose urine levels are considered representative of elastin breakdown. The aim of this study was to apply a novel methodology, based on high-performance capillary electrophoresis, to the quantificat...
Micellar electrokinetic chromatography (MEKC) using sodium dodecyl sulphate (SDS) in separation buffer has been employed for the separation and determination of acetylsalicylic acid and related compounds in tablets and bulk drugs. Base line separation was achieved by using 12.5 mM sodiumtetraborate decahydrate, 15 mM boric acid (pH 9.0) and 50 mM SDS. Analytical characteristics such as migratio...
A capillary electrophoresis Raman spectroscopy (CE-RS) method based on the stacking and sweeping modes are described. A non-fluorescent compound (malachite green, MG; crystal violet, CV) and a doubled Nd:YAG laser (532 nm, 300 mW) were selected as the model compound and light source, respectively. In order to carry out a quantitative and analysis of MG, a monochromator was used to collect the s...
Micellar electrokinetic chromatography (MEKC) was investigated for the simultaneous determination of letrozole, imipramine and their metabolites in human urine samples over a concentration range of therapeutic interest. Experimental parameters such as pH of the running electrolyte, sodium dodecylsulphate (SDS) concentration, borate concentration, voltage, etc were investigated. Under optimal co...
