Ambroxol Hydrochloride

A simple, sensitive, accurate, precise and rapid stability indicating HPTLC method for simultaneous determination of ambroxol hydrochloride and Loratadine in pharmaceutical dosage form has been developed. The study was performed on TLC aluminum plates precoated with silica gel 60F254 using chloroform: methanol (9:1v/v) as the mobile phase. This system gives compact and dense spots for both ambroxol hydrochloride (Rf value of 0.36±0.003) and loratadine (Rf value of 0.68±0.002). Densitometric analysis of both drugs was carried out in the reflectance absorbance mode at 216 nm. The coefficient of correlation data for the calibration plots showed a good linear relationship with R2 = 0.997 ± 1.1224 in the range of 600-3600 ng for ambroxol hydrochloride and R2 = 0.998 ± 0.0935 in the range of 50-300 ng for loratadine. The method was validated according to ICH guidelines for specificity, precision, robustness and recovery. Stability study shows that the chromatograms of samples from its degradation products were well resolved with significant Rf value.

A precise, accurate, economical and simple stability indicating RP-HPLC method was developed for the estimation of Amlodipine (AML) and Olmesartan (OLM) in bulk and pharmaceutical dosage form. Method was performed on a octadecyl silane column with dimensions 4.6 x 250 mm having particle size 5 micron. The mobile phase used in the method is TEA Buffer (pH 3.0) and acetonitrile in proportion of 25:75 respectively. The flow rate was maintained at 1.0 ml/ min and effluent was monitored at 258 nm. The drug was subjected to acid and alkali hydrolysis, oxidation, photolysis and heat as stress conditions. The method was validated for specificity, linearity, precision, accuracy, robustness and system suitability. The retention times were observed at 2.39 min and 3.33 min for AML and OLM respectively. The standard curve was found linear over a range of 05–35 μg/ml for AML and OLM. Similarly an average correlation coefficient was also obtained at 0.999 for AML and OLM. The limit of quantitation (LOQ) of this method was 2μg/ml for Amlodipine and Olmesartan. The absolute recovery was 100% for Amlodipine and 100.3 for Olmesartan. Degradation products produced as a result of stress studies did not interfere with the detection of AML and OLM and the assay can thus be considered stability-indicating.

Forced degradation experiments were carried out by exposing sacubitril and valsartan standard and sample for thermal, photolytic, oxidative and acid-base hydrolytic stress conditions.Results: Retention time of sacubitril and valsartan were found to be 4.170 min (minute) and 6.530 min (minute) respectively. The method has been validated for linearity, accuracy, precision, LOD, and LOQ. Linearity observed for sacubitril is 12.25-36.75 μg/ml (microgram per milliliter) and for valsartan is 12.75-38.25 μg/ml (microgram per milliliter). The results showed that sacubitril and valsartan and the other degradation products were fully resolved and thus the proposed method is stability-indicating.Conclusion: The proposed HPLC method was found to be simple, specific, precise, accurate, rapid and economical for simultaneous estimation of valsartan and sacubitril in bulk and tablet dosage form. Thus the validated economical method was applied for forced degradation study of sacubitril and valsartan tablet.

The effluents obtained were monitored at 237 nm with the UV-visible detector.Results: The retention time of aspirin, rosuvastatin, and clopidogrel was found to be 4.3 min, 7.6 min and 16.6 min respectively. For linearity seven-point calibration curves were obtained in a concentration range from 1-7 µg/ml for aspirin, rosuvastatin and clopidogrel with correlation coefficient 0.999, 0.9989, 0.9988 respectively. The high recovery values (99%-101%) indicate a satisfactory accuracy. The low percent relative standard deviation (% RSD) values in the precision study reveal that the method is precise. In the present study stability indicating an RP-HPLC method for the combination was tested by degrading the drugs together under various stress condition like acid, base and neutral hydrolysis, oxidation, thermal and photolytic stress which is recommended by ICH.Conclusion: The developed RP-HPLC method is simple, economic, specific, accurate and precise for the simultaneous estimation of aspirin, rosuvastatin, and clopidogrel in the combined capsule dosage form. The developed stability indicating analytical method can be used to check the stability of the compounds and was found suitable to determine % degradation of drugs in pharmaceutical dosage form.
