A simple, specific, accurate and precise reverse phase high pressure liquid chromatographic method has been developed for the simultaneous determination of Paracetamol and Lornoxicam from tablets and to characterize degradation products of Lornoxicam by reverse phase C18 column (Inertsil ODS 3V C-18, 250 x 4.6 mm, 5 ?). The sample was analyzed using Buffer (0.02504 Molar): Methanol in the ratio of 45:55, as a mobile phase at a flow rate of 1.5 mL/min and detection at 290 nm. The retention time for Paracetamol and Lornoxicam was found to be 2.45 and 9.40 min respectively. The method can be used for estimation of combination of these drugs in tablets. The method was validated as per ICH guidelines. The linearity of developed method was achieved in the range of 249.09 - 747.29 ?g/mL (r2=0.9999) for Paracetamol and 4.0125 - 12.0375 ?g/mL (r2=0.9999) for Lornoxicam. Recoveries from tablets were between 98 and 102%. The method was validated with respect to linearity, accuracy, precision, robustness and forced degradation studies which further proved the stability-indicating power. During the forced degradation studies lornoxicam was observed to be labile to alkaline hydrolytic stress and oxidative stress (in the solution form). However, it was stable to the acid hydrolytic, photolytic and thermal stress (in both solid and solution form). The degraded products formed were investigated by electrospray ionization (ESI) time-of-flight mass spectrometry, NMR and IR spectroscopy. A possible degradation pathway was outlined based on the results. The method was found to be sensitive with a detection limit of 0.193 ?g/ml, 2.768 ?g/ml and a quantitation limit of 0.638 ?g/ml, 9.137 ?g/ml for lornoxicam and paracetamol, respectively. Due to these attributes, the proposed method could be used for routine quality control analysis of these drugs in combined dosage forms.

Nilotinib hydrochloride is a tyrosine kinase inhibitor approved for the treatment of chronic myelogenous leukemia was subjected to forced degradation studies and the samples were analyzed by utilizing the LCMS compatible HPLC methods. Nilotinib Hydrochloride was subjected to thermal, hydrolytic, oxidative, acidic, basic and photolytic degradation conditions as per the regulatory guidelines. The drug was degraded in oxidative, basic and acidic environments and stable in photolytic and thermal conditions. The main degradation impurity components produced through the forced degradation study were isolated for the identification and quantification in presence of these impurities in the stability studies of drug substances as well as drug products. The identified degradation components were separated by mass assisted auto-purification technique and subjected for the characterization by NMR (13C-NMR, 1H-NMR, HMBC and HSQC), HRMS and FT-IR experimentations. Degradation products obtained from oxidative, basic and acidic environments were isolated and identified by the advanced techniques  as acid degradation product (DP-1) with molecular mass of 306.11 g/mol, empirical formula C17H14N4O2 with name as 4-methyl-3- (4 -(pyridine -3-yl) pyrimidin -2 -ylamino) benzoic acid. Base degradation product (DP-2) has molecular weight of 241.08 g/mol, molecular formula C11H10F3N3 with name as 3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)aniline.Oxidative degradation product (DP-3) has molecular weight of 545.18 g/mol, molecular formula C28H22F3N7O2 with name as 3-(2-(2-methyl-5-(3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)phenylcarbamoyl) phenylamino)pyrimidin-4-yl)pyridine1-oxide.

The stability of a new drug substances and new drug products is a vital parameter which may affect purity, safety & potency. Changes in drug stability can threat patient safety by formation of toxic degradation products or deliver to lower dose than expected. Therefore it is to know the purity profile & behaviour of a drug substances under the various environmental condition.  Forced Degradation studies show the chemical behavior of the molecule which in turn helps in the  development of  new formulation & package . Degradation study is required to the design of a regulatory compliant stability program for the both drug substances & products, and formalized as a regulatory requirement in ICH Guideline Q1A in 1993. Forced degradation studies (chemical and physical stress testing) of new chemical entities and drug product which is required to develop and demonstrate the specificity i.e stability indicating method. Forced degradation studies used to determination of the degradation pathways and degradation product of drug substances i.e during storage, development, manufacturing and packaging Thus , this review discusses the current trends in performance of forced degradation studies by provide the information about strategy for conducting the studies of forced degradation Keywords: - Regulatory Guidelines (ICH, FDA, EMA), Degradation condition, Forced degradation, Degradation product.

Chemometrics is the chemistry field responsible for planning and extracting the maximum of information of experiments from chemical data using mathematical tools (linear algebra, statistics, and so on). Active pharmaceutical ingredients (APIs) can form impurities when exposed to excipients or environmental variables such as light, high temperatures, acidic or basic conditions, humidity, and oxidative environment. By considering that these impurities can affect the safety and efficacy of the drug product, it is necessary to know how these impurities are yielded and to establish the pathway of their formation. In this context, forced degradation studies of pharmaceutical drugs have been used for the characterization of physicochemical stability of APIs. These studies are also essential in the validation of analytical methodologies, in order to prove the selectivity of methods for the API and its impurities and to create strategies to avoid the formation of degradation products. This review aims to demonstrate how forced degradation studies have been actually performed and the applications of chemometric tools in related studies. Some papers are going to be discussed to exemplify the chemometric applications in forced degradation studies.

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.
