ABSTRCT
Gatifloxacin is a antibacterial agent, Rapid, sensitive and selective analytical method is essential for monitoring the different reactions steps involved in process development of Gatifloxacin. A simple isocratic reverse phase High Performance Liquid Chromatographic [HPLC] method was developed for simultaneous separation of different intermediates and other impurities. The method was utilized successfully in analyzing the reaction streams, related substances in final product and for the assay in drug.

ABSTRACT
To make drugs serve their purpose various chemical and instrumental methods were developed and regular intervals which are involved in the estimation of drugs. A photoelectric flame photometer is a device used in inorganic chemical analysis to determine the concentration of certain metal ions, among them sodium, potassium, lithium, and calcium. Group 1 and Group 2 metals are quite sensitive to Flame Photometry due to their low excitation energies ^[1].These pharmaceuticals would serve their intent only if they are free from impurities and are administered at appropriate amounts ^[2] . These pharmaceuticals develop impurities at various stages of their development, transportation and storage which makes the pharmaceuticals risky to be administered thus they may be detected and quantified. For this analytical instrumentation and methods play important role. This review highlights a variety of analytical techniques for analysis of inorganic elements. Analytical techniques for analysis of inorganic elements. The most commonly used techniques for the determination of inorganic elements is atomic spectroscopy the different branches of atomic absorption spectroscopy are(1) flame photometry or flame atomic emission spectrometry. (2) atomic absorption spectrophotometer, (aas). (3) inductively coupled plasma-atomic emission spectrometry (icp-aes).(4) uv - visible spectrophotometer.

ABSTRACT
Purpose: A simple, precise, accurate, rapid and economical reverse phase high-pressure liquid chromatographic method has been developed as per ICH norms for the estimation of Naproxen from pharmaceutical formulation.
Methods: The method was carried out on a Kromosil-C₁₈ ODS column (150 mm X 4.6 mm; 5 µ) with a mobile phase consists of ammonium acetate buffer (adjusted to pH 4.0 with 1 % Triethyl amine): methanol (40:60 v/v) and filtered through a 0.45 µ cellulose nitrate filters. The flow rate was maintained in isocratic mode at 1.0 mL/min. The detection was carried out at 210 nm. The run time was 7.0 min.
Results: The retention time was 3.063 min for Naproxen. The developed method was validated in terms of accuracy, precision, linearity, limit of detection, limit of quantification and solution stability.
Conclusion: The proposed method was adequate sensitive, reproducible, and specific for the determination of Naproxen in bulk as well as in tablet dosage forms.

ABSTRACT
Objective: The present work was undertaken with the aim to develop and validate a rapid and consistent RP-HPLC method in which the peaks will be appear with short period of time as per ICH Guidelines.
Method: The HPLC separation was achieved on an Inertsil-C₁₈ ODS column (250 X 4.6 mm; 5 µ) column in an Isocratic Mode. The mobile phase composed of Methanol [HPLC Grade] (55 %) and Buffer (45 %) [pH 4.0 adjusted with triethylamine]. The flow rate was monitored at 1.0 mL/min. The wavelength was selected for the detection was 276 nm.
Results:The retention times found for rabeprazole and mosapride was 2.946 and 4.186 min respectively. The % recovery was 99.98- 100.03 for rabeprazole and 99.97 - 100.02 for mosapride. The linearity was established in the range of 20-80 µg/mL for both rabeprazole and mosapride. The LOD for rabeprazole and mosapride were 0.01 and 0.035 µg/mL respectively. The LOQ for rabeprazole and mosapride were 0.032and 0.11 µg/mL respectively.
Conclusion:The proposed method was adequate sensitive, reproducible, and specific for the determination of rabeprazole and mosapride in bulk as well as in tablet dosage forms.

ABSTRACT:
The simple spectroscopic method has been developed for simultaneous estimation of Lamotrigine and Clozapine in synthetic mixture. Absorbance Correction Method involves the measurement of absorption at two wavelengths 307 nm (l_maxfor Lamotrigine) and 360 nm (l_maxfor Clozapine). The method was found linear between the range of 1-5 µg/ml for Lamotrigine and 6-30 µg/ml for Clozapine for method. The accuracy and precision was determined and validated statistically. Both the method showed good reproducibility and recovery with %RSD less than 1. The method was found to be rapid, specific, precise and accurate and can be successfully applied for the routine analysis for Lamotrigine and Clozapine in bulk and combined dosage form.
