An attempt has been made to develop a simple, sensitive and rapid high performance liquid chromatographic (HPLC) method of analysis for sparfloxacin using 35% acetonitrile in buffer solution as mobile phase. Buffer solution (40 mM of sodium dihydrogen phosphate in de-ionized water) was used as solvent to dissolve sparfloxacin and 0.05mg/ml stock solution was prepared. Sparfloxacin solution was scanned with UV-spectrophotometer and the absorption maximum (λmax) was found at 292 rim. This method was successfully applied to four tablet dosage forms of sparfloxacin encoded as ?, ?, ?, and ?, from four different companies and the result was found to be satisfactory and reproducible.

A rapid and reproducible reverse phase high performance liquid chromatographic method has been developed for the estimation of lamotrigine in its pure form as well as in pharmaceutical dosage forms. Chromatography was carried out on a Luna C18column using a mixture of potassium dihydrogen phosphate buffer (pH 7.3) and methanol in a ratio of 60:40 v/v as the mobile phase at a flow rate of 1.0 mL/min. The detection was done at 305 nm. The retention time of the drug was 6.1 min. The method produced linear responses in the concentration range of 10 to 70 μg/mL of lamotrigine. The method was found to be reproducible for analysis of the drug in tablet dosage forms.

A simple, selective, accurate High Performance Liquid Chromatographic (HPLC) method was developed and validated for the analysis of Fenspiride hydrochloride in bulk and tablet dosage forms. Chromatographic separation was achieved isocratically using a C18 reverse phase column [Inertsil C18 column (250×4.6mm, 5μm)] utilizing a mobile phase containing 10mM Ammonium acetate: Acetonitrile (50:50 v/v) at a flow rate of 1 mL/min. The eluents were monitored at wavelength of 210 nm for a run time of 7 minutes at ambient temperature. The average retention time of the drug was found to be 4.6 minutes. The developed method was validated as per ICH guidelines to ascertain the reproducibility of the method. The method was found to be linear in the concentration range of 10-50 μg/mL with a good correlation coefficient of 0.998. The limit of detection (LOD) and limit of quantification (LOQ) were 0.007 and 0.021 μg/mL and the percentage recovery and assay were found to be 99.315 and 98.97%. Specificity with placebo by 3 D plots showed that the method was specific and free from interfering substances. Therefore, the fully validated method was good enough to carry out routine analysis of Fenspiride in bulk and tablet formulations.
