“…The results were obtained using the calibration plot. The obtained results (Table 3) were statistically compared with those obtained by a reported micellar LC method [6]. Since calculated value of F does not exceed the theoretical value (Table 3), there was no significant difference between the proposed and reported methods with respect to reproducibility [21].…”

“…Several methods for determination of tolmetin in pharmaceutical formulation and human fluids, including spectrophotometry [3,4], supercritical fluid chromatography [5], micellar liquid chromatography [6] high performance liquid chromatography [7][8][9][10][11][12], electroncapture gas chromatography [13], liquid chromatography [14], and differential-pulse polarography [15], have been reported in the literature. The reported chromatographic methods for quantitation of tolmetin require sample pretreatment or time-consuming extraction prior to the analysis, as well as expensive reagents and equipment, which are too expensive for routine pharmaceutical analysis.…”

Abstract:The electro-reduction of tolmetin at the hanging mercury drop electrode was studied in different supporting electrolytes using cyclic voltammetry and square-wave stripping voltammetry techniques. Voltammograms of tolmetin exhibited a single well-defined 2-electron irreversible cathodic peak in media of pH < 4, which may be attributed to reduction of the >C=O double bond of the analyte molecule. Adsorption of tolmetin onto the surface of the hanging mercury electrode was identified and each adsorbed tolmetin molecule was found to occupy an area of 0.23 nm 2 . A square-wave adsorptive cathodic stripping voltammetric procedure was described for the direct determination of tolmetin in bulk form and pharmaceutical formulation (Rumatol R capsules) with a limit of quantitation of 2 × 10 −9 M and a mean percentage recovery of 98.35 ± 1.21% to 99.57 ± 1.23. Moreover, the described procedure was successfully applied for the direct assay of tolmetin in spiked human serum without pretreatment or extraction prior to the analysis while a quantitation limit of 5 × 10 −9 M tolmetin was achieved.

“…For more complex dosage forms such as ointment, cream, or gel, a suitable amount is weighed and mixed with the micellar mobile phase with the aid of sonication, or mechanical stirring [6]. For suppositories, one unit is dissolved in n-propanol, butanol, or pentanol (according to the mobile phase composition) with the aid of sonication and gentle heating, and then suitable volumes are diluted with the mobile phase then chromatographed [26].…”

Micellar liquid chromatography (MLC) is a simple well-established branch of high-performance liquid chromatography. The applications of MLC for the determination of numerous compounds in pharmaceutical formulations, biological samples, food, and environmental samples have been growing very rapidly. MLC technique has several advantages over other techniques, such as simultaneous separation of charged and uncharged solutes, rapid gradient capability, direct on-column injection of physiological fluids, unique separation selectivity, high reproducibility, robustness, enhanced luminescence detection, low cost, and safety. This review is devoted to the evaluation of the agreement of MLC with the principles of green chemistry which recently represents a universal trend. Also, it provides an overview on the basics of MLC, in addition to a survey of MLC methods published in the past five years for the assay of various compounds in different matrices.

“…Martinez‐Algaba et al . () made an attempt to study possibilities of separation of nonsteroidal anti‐inflammatory drugs – acemetacin, diclofenac, indometacin, ketoprofen, piketoprofen and tolmetin – using the micellar chromatographic systems in which, besides SDS, the cationic CTAB was a main component of mobile phases. The stationary phases RP 8 and RP 18 were used in the studies.…”

The features of micellar systems are outstanding compared with conventional RP-LC ones. Therefore, the unique properties of micellar chromatography (MLC) are widely recognized. In this short review the applicability of MLC as an in vitro method for the determination of biological activity is discussed. For this purpose many specific examples of MLC applications supported by the theoretical backgrounds of the cited biological activity areas as well as the factors affecting them are presented. This study collects and organizes the most important references of bioactivity determination which were created both recently and in the past, using the MLC method. Although there are many papers on the MLC there is no literature review focused particularly on its applicability in the study of biological activity of various compounds. This work can be treated as a significant review of so far published papers which particularly emphasizes the importance of MLC as in vitro method for determination of bioactivity of different compounds.
