Objective: Therefore the aim of the present work was to develop simple, precise and accurate HPTLC method for simultaneous determination of THIO and ACE in pharmaceutical dosage form and application of the method for dissolution study with help of HPTLC method.Methods: The TLC procedure was optimized in view to develop a simultaneous assay method for THIO and ACE. HPTLC Pre-coated plates silica gel 60 F254 20×10 cm, layer thickness 0.2 mm (Merck, Germany). The samples were spotted in the form of bands (8 mm) with a Camag 100 microliter sample (Hamilton) syringe on silica gel precoated aluminium 60F254 plates. The mobile phase consisted of methanol: chloroform: water (9.6: 0.2: 0.2 v/v/v) and 10 ml of mobile phase were used per chromatography run. Plates were scanned over the range of 200-400 nm and the spectra were overlain.Results: The detector response was found to be linear in the concentration range of 0.03-0.180 µg/band and 0.75-4.5 µg/band for THIO and ACE and noting the peak areas. Accuracy of the assay method was evaluated with the recovery of the standards from excipients. The mean percentage recoveries obtained for THIO and ACE were 99.34% and 99.08%, respectively, reported. The peak purity of both drugs was assessed by comparing the respective spectra of standard drugs and samples at peak start, peak apex and peak end positions of the spot.Conclusion: HPTLC, with its advantage of low operating cost, high sample thought and minimum sample preparation need is now days preferred as routine analytical techniques for control and assurance. The validated HPTLC method employed here proved to be simple, fast, accurate, precise and sensitive, thus can be used for routine analysis of Thiocolchicoside and Aceclofenac in tablet dosage form.

A simple validated RP HPLC method for the estimation of rizatriptan benzoate in pharmaceutical dosage form and bulk was developed for routine analysis. This method was developed by selecting Agilent TC C18 (250 x 4.6 mm, 5 μ) column as stationary phase and acrylonibrile:water (45:55), pH adjusted to 3, as mobile phase. Flow rate of mobile phase was maintained at 4: 1 mL/min at ambient temperature throughout the experiment. Quantification was achieved with ultraviolet (DAD) detection at 220 nm. The retention time obtained for rizatriptan was 2.8 min. The detector response was linear in the concentration range of 2-25μg/mL. This method was validated and shown to be specific, sensitive, precise, linear, accurate, rugged and robust. Hence, this method can be applied for routine quality control of rizatriptan benzoate in dosage forms as well as in bulk drug.

Abstract A simple, rapid, and reliable ultra-performance LC assay method has been developed for the simultaneous estimation of orally administered hypertension drugs (atenolol, hydrochlorothiazide, amlodipine besylate, indapamide, nifedipine, and lercanidipine hydrochloride), any of which may be administered with atenolol in combined hypertension therapy. Chromatography was carried out at 25°C on a 2.1 × 50 mm id, 1.7 μm particle size Acquity BEH C18 column with the isocratic mobile phase 0.01 M, 4.0 pH aqueous phosphate buffer–acetonitrile (50 + 50, v/v) at a flow rate of 0.35 mL/min. All drugs were separated in less than 4 min with good resolution and minimal tailing, without interference by excipients. The method was validated according to International Conference on Harmonization guidelines, and the acceptance criteria for accuracy, precision, linearity, specificity, and system suitability were met in all cases. The column effluent was monitored at 230 nm. The detector response was linear in the range of 1–20 μg/mL of these drugs. LOD obtained was 0.04 μg/mL for atenolol, 0.02 μg/mL for hydrochlorothiazide, 0.03 μg/mL for amlodipine besylate, 0.03 μg/mL for indapamide, 0.02 μg/mL for nifedipine, and 0.01 μg/mL for lercanidipine hydrochloride. The suggested method has the advantage that all the drugs can be quantified alone or in combination with atenolol using a single mobile phase.
