Background: Regadenoson is an A2A adenosine receptor agonist that is a coronary vasodilator and commonly used as a pharmacologic cardiac stressing agents. Methods: HPLC method was used for the analysis of related substances. The degraded impurities during the process were isolated and characterized by IR, Mass and NMR spectral analysis. Results: Forced degradation study of regadenoson under conditions of hydrolysis (neutral, acidic and alkaline) and oxidations suggested in the ICH Q1A(R2) was accomplished. The drug showed significant degradation under all the above conditions. On the whole, five novel degradation products were found under diverse conditions along with process related impurities which were not reported earlier. Conclusion: All the degradation products were well characterized by using advanced spectroscopic techniques like IR, 1H NMR, 13C NMR and Mass spectra. The identification of these impurities will be productive for the quality control during the production and stability behavior of the regadenoson drug substance.

Hplc Method Development

A simple, precise and stability-indicating RP-HPLC method was developed for simultaneous quantification of oxycodone (OXCD) and naltrexone (NTRX) in combined dosage form. The developed method was validated with respect to precision, linearity, accuracy, robustness, ruggedness, sensitivity and solution stability. The method was developed with ammonium di hydrogen phosphate buffer (pH 5.0) and acetonitrile in a ratio of 55:45 (v/v) as mobile phase at a flow rate of 1.0 mL/minute over Intersil ODS C18 column (250 mm × 4.6 mm×5μ).The UV detection wavelength was fixed at 235 nm. The column temperature was maintained at ambient temperature. The method showed good linearity with correlation coefficient values of 0.9990 and 0.9994 for OXCD and NTRX. The percent recoveries of the two drugs found within the limits of 98.0–102.0%. The LOQ concentrations of OXCD and NTRX are 0.625 μg/ mL and 0.075 μg/mL, respectively. The LOD concentrations of OXCD and NTRX are 0.3125 μg/mL and 0.0375 μg/mL, respectively. According to ICH guidelines forced degradation study was validated.

Isocratic Mode

A simple, fast, precise and accurate ultra high performance liquid chromatography method was developed for degradation study of eletriptan hydrobromide (EH) under exaggerated conditions. An Inertsil ODS C18 (250 x 4.6 mm, 5µm) column in isocratic mode was used with mobile phase comprising of water, methanol and trifluoroacetic acid mixed in the ratio 55:45:0.1 % V/V/V, maintained at pH 3.5. The flow rate was set at 0.4 mL per minute with UV detection at 225 nm. The retention time of EH was found to be 3.7 minutes. Linearity for EH was found in the range of 3.5- 200 µg per mL and percentage recoveries were obtained in the range of 100.2 % to 100.6 %. The method was capable of resolving all degradants and principle component in sample. The proposed method is accurate, precise, selective, reproducible, and rapid for detection of degradation of eletriptan hydrobromide.

Abstract A forced degradation study was successfully applied for the development of a stability-indicating assay method for determination of rosuvastatin Ca in the presence of its degradation products. The method was developed and optimized by analyzing the forcefully degraded samples. Degradation of the drug was done at various pH values. Moreover, the drug was degraded under oxidative, photolytic, and thermal stress conditions. Mass balance between assay values of degraded samples and generated impurities was found to be satisfactory. The proposed method was able to resolve all of the possible degradation products formed during the stress study. The developed method was successfully applied for an accelerated stability study of the tablet formulation. The major impurities generated during the accelerated stability study of the tablet formulation were matches with those of the forced degradation study. The developed method was validated for determination of rosuvastatin Ca, and the method was found to be equally applicable to study the impurities formed during routine and forced degradation of rosuvastatin Ca.
