A simple and sensitive thin-layer chromatographic method has been established for analysis of rasagiline mesylate in pharmaceutical dosage form. Chromatography on silica gel 60 F254 plates with 6 : 1 : 2(v/v/v) butanol-methanol water as mobile phase furnished compact spots at Rf  0.76±0.01. Densitometric analysis was performed at 254 nm. To show the specificity of the method, rasagiline mesylate was subjected to acid, base, neutral hydrolysis, oxidation, photolysis, and thermal decomposition, and the peaks of degradation products were well resolved from that of the pure drug. Linear regression analysis revealed a good linear relationship between peak area and amount of rasagiline mesylate in the range of 100–350 ng/band. The minimum amount of rasagiline mesylate that could be authentically detected and quantified was 11.12 and 37.21 ng/band, respectively. The method was validated, in accordance with ICH guidelines for precision, accuracy, and robustness. Since the method could effectively separate the drug from its degradation products, it can be regarded as stability indicating.

Objective: This study aims to develop and validate a stability indicating HPLC method for simultaneous estimation of sacubitril and valsartan in pharmaceutical dosage form.Methods: Sacubitril and valsartan separation were achieved by LC-20 AT C18 (250 mm x 4.6 mm) column and buffer (potassium phosphate, pH 3.0): methanol (50:50) as mobile phase, at a flow rate of 1 ml/min (millilitre per minute). Detection was carried out at 224 nm (nanometer). The different HPLC experimental parameters were optimized and the method was validated according to the standard guideline. 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.

A simple, inexpensive, rapid and novel stability indicating isocratic HPLC method has been developed and validated for quantitative analysis of ertapenem sodium in the bulk drug and in pharmaceutical dosage form. An isocratic separation of ertapenem sodium was achieved on Hypersil BDS C18 column (4.6 x 250 mm, 5 ? particle size) as the stationary phase with a flow rate of 1.2 ml/min and using a UV detector to monitor the eluate at 298 nm. The mobile phase consisted of acetonitrile : water (60:40v/v) and pH adjusted 2.9 by othophosphoric acid enabled separation of the drug from its degradation products. The method was validated for linearity, accuracy (recovery), precision, specificity and robustness. The linearity of the method was satisfactory over the range 2-10 ?g/ml (correlation coefficient 0.999). Recovery of ertapenem sodium from the pharmaceutical dosage form ranged from 99.97 to 103.7%. Ertapenem sodium was subjected to stress conditions [hydrolysis (acid, base), oxidation, photolysis and thermal degradation] and the samples were analyzed by this method. The forceddegradation study with ertapenem sodium showed that it was degraded under basic condition. The drug was stable under the other stress conditions investigated. Ertapenem sodium was found to be less stable in solution state, whereas it was comparatively much stable in solid state. The degradation products were well resolved from main peak. The forced degradation study prove the stability indicating power of the method and therefore, the validated method may be useful for routine analysis of ertapenem sodium as bulk drug, in respective dosage forms, for dissolution studies and as stability indicating assay method in pharmaceutical laboratories and industries.Dhaka Univ.
