AbstractForced degradation study is a systemic characterization of degradation products of active pharmaceutical ingredient (API) at conditions which posses more harsh environment that accelerates degradation of API. Forced degradation and stability studies would be useful in selection of proper, packaging material and storage conditions of the API. These are also useful to demonstrate degradation pathways and degradation products of the API and further characterisation of the degradation products using mass spectrometry. TGR5 is a G protein-coupled receptor, activation of which promotes secretion of glucagon-like peptide-1 (GLP-1) and modulates insulin secretion. The potent and orally bioavailable TGR5 agonist, ZY12201, shows activation of TGR5 which increase secretion of GLP-1 and help in lowering blood glucose level in animal models. Hence it is necessary to establish and study degradation pathway and stability of API for better handling and regulatory approval. Force degradation studies of ZY12201 have shown presence of one oxidative impurity during oxidative degradation in HPLC analysis. The oxidized product is further characterized by LC–MS to elucidate structure of impurity and characterize its degradation pathway.

Forced Degradation Studies

Forced degradation study is the degradation of new drug substances and drug products in more severe conditions than accelerated conditions. Forced degradation study were conducted to demonstrate the specificity of stability-indicating methods, providing insight into degradation pathways and drug degradation products, assisting in the elucidation of degradation product structures, identifying degradation products that could be spontaneously generated during storage and use of drugs and to facilitate improvement in manufacturing process and formulation corresponding with accelerated stability studies. Statins, a class of lipid-lowering medications, are the most widely prescribed drugs and an example of an unstable drug. Statins are susceptible to hydrolysis in the presence of high temperatures and humidity. Therefore, the review discusses various studies of forced degradation studies in six statins drug (atorvastatin, fluvastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin) to describe the drug's intrinsic stability thus it can assist the selection of formulations and packaging as well as proper storage conditions.

Stability testing is used to provide evidence of how the quality of an Active Pharmaceutical Ingredient (API) or drug product varies with time under the infuence of a variety of environmental factors such as temperature, humidity and light. If drug product is not stable under various environmental conditions, it may affect the patient safety by formation of a toxic degradation product(s) or deliver a lower dose than expected. Stress testing of the API can help to identify the likely degradation products, which, in turn, can help to establish the degradation pathways and the intrinsic stability of the molecule. Forced degradation study is a process in which the natural degradation rate of a pharmaceutical product is increased by applying an additional stres by which stability of a drug substance or a drug product with effects on purity, potency and safety can be predicted. The present review summarizes the forced degradation study of antihypertensive agents, where degradation products for different stress conditions have been reported. As per review, maximum degradation products have been reported by alkaline, oxidative and photolytic stress conditions.

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.

Venetoclax is an orally bioavailable, B-cell lymphoma-2 (BCL-2) selective inhibitor, used for the treatment of various types of blood cancers, such as chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). In this study we investigated the degradation of venetoclax under various stress conditions including acidic, basic, oxidative, photolytic and thermolytic conditions. We isolated and identified six of its main degradation products produced in forced degradation studies. The structures of the isolated degradation products were determined by using nuclear magnetic resonance (NMR) spectroscopy, high resolution mass spectrometry (HRMS) and infrared (IR) spectroscopy. Additionally, one oxidation degradation product was identified with comparison to a commercially obtained venetoclax impurity. We proposed the key degradation pathways of venetoclax in solution. To the best of our knowledge, no structures of degradation products of venetoclax have been previously published. The study provides novel and primary knowledge of the stability characteristics of venetoclax under stress conditions. Venetoclax is currently the only BCL-2 protein inhibitor on the market. In addition to single agent treatment, it is effective in combinational therapy, so future drug development involving venetoclax can be expected. A better insight into the stability properties of the therapeutic can facilitate future studies involving venetoclax and aid in the search of new similar therapeutics.

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.

Objective: The current study focused on the development, validation, and characterization of forced degradation products using LC-MS/MS. Methods: A simple, selective, validated and well-defined isocratic HPLC methodology for the quantitative determination of Tucatinib at a wavelength of 239 nm. An isocratic elution of samples was performed on an Inertsil ODS (250x4.6 mm, 5m) column with a mobile phase of 70:30v/v Acetonitrile and formic acid (0.1%) delivered at a flow rate of 1.0 ml/min. MS/MS was used to characterize degradation products formed in the forced degradation study. The validation and characterization of forced degradation products were performed in accordance with ICH guidelines. Results: Over the concentration range of 5-100μg/ml, a good linear response was obtained. Tucatinib's LOD and LOQ were determined to be 0.05 and 0.5, respectively. According to standard guidelines, the method was quantitatively evaluated in terms of system suitability, linearity, precision, accuracy, and robustness, and the results were found to be within acceptable limits. The drug was degraded under acidic, alkaline, and reduction conditions in forced degradation studies. Conclusion: The method was found to be applicable for routine tucatinib analysis. Because no LC-MS/MS method for estimating tucatinib and its degradation products has been reported in the literature. There is a need to develop a method for studying the entire tucatinib degradation pathway.
