Amoxicillin, substance-related to semisynthetic penicillin, has been widely used to treat infections caused by various microorganisms, however reports of suitable methods for the quantitative determination and indicative of the stability of formulations containing this substance are rare. Due to lack of studies on the forced degradation of the substance and on the need to monitor the quality of this type of formulation was proposed and validated a method for the determination of amoxicillin content in capsules by high-performance liquid chromatography - HPLC for the quality control of amoxicillin capsules, allowing the provision of useful information about the characteristics of this type of formulation and its stability. The method was validated for parameters of linearity, specificity, accuracy, precision, and robustness

ABSTRACTObjective: To development and validation of a reversed-phase high-performance liquid chromatography (RP-HPLC) for the determination of modafinilin bulk and pharmaceutical dosage forms.Methods: A simple, precise, rapid, and accurate RP-HPLC method was developed for the estimation of modafinil in bulk and pharmaceutical dosageforms. Xterra RP 18 (250 mm × 4.6 mm, 5 µ particle size) with a mobile phase consisting of methanol:water 70:30 V/V was used. The flow rate1.0 ml/min and the effluents were monitored at 260 nm. The retention time and recovery time was 12 minutes. The detector response was linear inthe concentration of 10-50 µg/ml. The respective linear regression equation being Y=452.1x+65237. The limit of detection and limit of quantificationwere 4.547 and 1.377 mcg, respectively. The method was validated by determining its accuracy, precision, and system suitability.Result: The objective of the present work is to develop simple, precise, and reliable HPLC method for the analysis of modafinil in bulk andpharmaceutical dosage forms. This is achieved using the most commonly employed Xterra RP 18 (250 mm × 4.6 mm, 5 μ particle size) columndetection at 260 nm. The present method was validated according to ICH guidelines.Conclusion: In this study, a simple, fast and reliable HPLC method was developed and validated for the determination of modafinil in pharmaceuticalformulations.Keywords: Modafinil, Reversed-phase high-performance liquid chromatography, Estimation, ICH guidelines, Tablets.

The Stability

A simple, rapid and sensitive Spectrophotometeric method for the determination of fluoroquinolones; ciprofloxacin and levofloxacin have been performed in pure form and pharmaceutical tablets. Both drugs gave reddish complexes when treated with iron (III) chloride at pH 4.0. The drugs showed maximum absorption at 530 and 545 nm. In both cases linear calibration was obtained up to 0.9 mg/10 mL of the drug. Effect of different parameters like pH, temperature and time was also studied on the stability of the complexes. The percentage recoveries found by described method was in the range of 98.2---100.01 %. Standards were prepared from the pure compounds obtained from sigma-Aldrich Pharm. The method was successfully employed for the Assay of drugs in commercial formulations. Finally determination of the drugs was carried out through HPLC method which showed that there is no appreciable difference between the results of both the methods. Results revealed that proposed method is practically suitable for routine applications in quality control laboratories for the analysis of fluoroquinolones drugs.________________________________________GRAPHICAL ABSTRACT
