“…Driving forces in CE are electrophoretic migration and the electro-osmotic flow (EO F ) . C E h a s b e c o m e a u s e f u l t o o l i n pharmaceutical analysis because of its advantages over other separation techniques, such as high resolution, high selectivity, simplicity, short analysis time, cost efficiency and low consumption of solvents and reagents [102]. Mainly employed CE modes for drug analysis are capillary zone electrophoresis (CZE) based on charge-to-mass ratio and micellar electrokinetic chromatography (MEKC) based on chromatographic partition of analytes between micelles and background electrolyte.…”

“…Due to the vast exploration in this subject, numerous reviews detailing fundamentals and applications can be found in the literature prior to 2005 [6][7][8][9][10][11] and over the past two years [12][13][14][15]. Reviews have also covered methods developed specifically for pharmaceutical compounds [16][17][18][19][20][21][22], biological compounds [23], chiral LC-MS/ CE-MS [24], pesticides [25], pollutants [26], and food additives [27,28].…”

Review of aqueous chiral electrokinetic chromatography (EKC) with an emphasis on chiral microemulsion EKCThe separation of enantiomers using electrokinetic chromatography (EKC) with chiral microemulsions is comprehensively reviewed through December 1, 2006. Aqueous chiral EKC separations based on other pseudostationary phases such as micelles and vesicles or on other chiral selectors such as CDs, crown ethers, glycopeptides, ligand exchange moeities are also reviewed from both mechanistic and applications perspective for the period of

“…[8][9][10] The use of CE in the pharmaceutical analysis has increased in recent years and includes drug assays, chiral separation, and analysis of pharmaceutical excipients of drug related impurities. 11) CE separations are generally more efficient, can be performed faster and require only nanoliter injection volumes. 12) Capillary zone electrophoresis (CZE) and micellar electrokinetic chromatography (MEKC) are the two most widely used separation modes of this technique.…”

A simple, stability-indicating micellar electrokinetic chromatography (MEKC) method was developed and validated for the analysis of mianserin hydrochloride in coated tablets. The method employed (hydroxymethyl)aminomethane (TRIS) 50 mM to which sodium dodecyl sulfate (SDS) 50 mM was added at pH 10.6 as the electrolyte and the voltage applied was 25 kV. The capillary used was 48.5 cm long (40.0 cm effective length and 50.0 µm i.d.) and the detection wavelength was 220 nm. Tetracycline was used as internal standard. The method was validated in accordance with the International Conference on Harmonization (ICH) requirements, which involved specificity, linearity, precision, accuracy and robustness. The stability-indicating capability of the method was established by enforced degradation studies combined with peak purity assessment using photodiode array detection. The degradation products formed under photolytic and oxidative conditions were investigated by electrospray ionization mass spectrometry. The method was linear over the concentration range of 50-130 µg/mL. The method was precise as demonstrated by an inter-day and intra-day relative standard deviation of less than 2.0%. The proposed validated MEKC method showed recoveries between 98.16 and 102.80% of the nominal contents. The Plackett-Burman design was applied for the robustness test in order to examine potential sources of variability by screening a large number of factors in a relatively small number of experiments.Key words capillary electrophoresis; mianserin hydrochloride; mass spectrometry Mianserin hydrochloride (Fig. 1) is a drug for the treatment of depressive illness and depression associated with anxiety. Its antidepressant effect is mainly attributed to presynaptic alfa2-adrenoreceptor blocking activity and to serotonin receptor antagonism. Mianserin is classified as an atypical antidepressant, based on its undefined action mechanism. 1)This drug is considered a weak base with two pK a values (2.7, 8.26) and chemically known as (RS)-2-methyl-1,2,3,4,10,14b-hexahydrodibenzo[c, f ] pyrazino[1,2-α] azepine hydrochloride. In humans, its major metabolic pathways include 8-hydroxylation, N-demethylation, and N-oxidation catalyzed mainly by CYP2D6, and by CYP3A4 and 1A2.2) In rats, the additional metabolite, 8-hydroxy-N-desmethylmianserin is formed from 8-hydroxyminaserin and/or N-desmethylmianserin. 3)From the analytical point of view, methods for its determination in biological fluids [4][5][6] and dosage form 7) have been reported. However, none of the reported methods for the determination of mianserin hydrochloride was shown to be a stability-indicating. It was therefore important to develop and validate a capillary electrophoresis stability-indicating method for this major compound, that can be employed in stability studies and routine quality control of its preparations. In the literature were found three relevant publications on the determination of mianserin enantiomers by capillary electrophoresis (CE). [8][9][10] The use of CE in the pharm...
