A stability indicating HPTLC method was developed and validated for fixed dose combination of cefpodoxime proxetil and ofloxacin. TLC plates precoated with silica gel 60F254 were used as stationary phase and n propanol: ammonia (7:3 v/v) was used as mobile phase. Densitometric scanning was carried out at 290nm. Specificity of the method was established by peak purity studies. Method was validated as per ICH guidelines Q2 (R1) for accuracy, precision, linearity, sensitivity and robustness. Both the drugs were subjected to hydrolytic (acidic and basic), oxidative, thermal and photolytic stress as per ICH guidelines Q1A (R2) and Q2B. Forced degradation studies were performed by using design of experiments approach, the most widely used mathematical model. Such experimental design approach can replace conventional trial and error experimentation to achieve optimum degradation.

Abstract Background A sensitive, precise, and stability-indicating high-performance thin-layer chromatographic (HPTLC) method has been developed for the analysis of Remogliflozin etabonate in tablet formulation. HPTLC plates precoated with silica gel 60 F254 were used as the stationary phase; methanol: ethyl acetate: toluene: NH3 (2:4:4:0.1, v/v/v) was used as mobile phase, and densitometry was used for the quantitative estimation of the drug. The proposed method was validated with respect to linearity, accuracy, precision, and robustness and applied for the estimation of drug in tablet dosage form. Results The Rf value of Remogliflozin etabonate was observed to be 0.61. The densitometric estimation was performed in reflectance mode at 229 nm. The method was found to be linear in the range of 500–8000 ng/band for Remogliflozin etabonate. The possible degradation pathway was estimated by performing forced degradation studies. The degradant peaks were well resolved from the drug peak with acceptable resolution in their Rf value. Conclusion An accurate and precise high-performance thin-layer chromatographic method has been developed for the quantification of Remogliflozin etabonate in tablets. Forced degradation studies were performed, and drug was found to be highly susceptible to acid, base hydrolysis, and oxidative stress degradation and gets converted into active drug Remogliflozin. Both Remogliflozin etabonate and Remogliflozin bands were well resolved. The method was applied for the analysis of drug in tablet formulation, and it can be used for routine quality control analysis, as well as for the analysis of stability samples.

Objective: To develop an accurate, simple, precise and specific stability indicating RP-HPLC method for estimation of dimethyl fumarate in bulk and capsules.Methods: An Inertsil ODS (150x4.6 mm, 5µ) column and a mobile phase containing acetonitrile: potassium dihydrogen phosphate buffer pH 6.8 (50:50% v/v) was used for this study. The flow rate was maintained at 1.0 ml/min; column temperature was fixed at 35 °C and UV detection was carried out at 210 nm. The forced degradation studies were performed and method was validated with as per ICH guidelines.Results: The retention time of dimethyl fumarate was found to be 3.3±0.02 min. The value of correlation coefficient between peak area and concentration was found to be 0.9993. The mean percent recovery of dimethyl fumarate in capsules was found in the range of 99.65 to 101.64%. The results of forced degradation studies indicated that the drug was found to be stable in basic, oxidative and thermal conditions while degraded in acidic conditions.Conclusion: It can be conducted from results that the developed HPLC method is simple, accurate, precise and specific. Results of stress testing study revealed that the method is stability indicating. Thus, this method can be used for routine analysis of dimethyl fumarate capsules and check their stability.

Nilotinib hydrochloride monohydrate is a tyrosine kinase inhibitor approved for the treatment of chronic myelogenous leukemia. A new stability indicating ultra-fast liquid chromatographic (RP-UFLC) method was developed for the quantification of Nilotinib and validated. Mobile phase consisting of a mixture of sodium acetate (pH 5.0): acetonitrile (40: 60, v/v) was used with flow rate 0.8 mL/min (UV detection at 254 nm) for the chromatographic study. Nilotinib obeys Beer-Lambert’s law over the concentration range of 0.2-80 μg/mL (R2 = 0.9999) with linear regression equation y = 175336x +20675. The LOQ was found to be 0.1897 μg/mL and the LOD was found to be 0.0619 μg/mL. Forced degradation studies were performed such as acidic, alkaline, oxidation and thermal degradations and the method was validated as per ICH guidelines.
