Stability Indicating Method

Aim/Background: In this study, a stability-indicating method of the anticancer agent cabazitaxel was developed and validated. This method will be used to determine the chemical stability of commercially available concentrate-solvent mixture cabazitaxel (Jevtana®) to examine the possibility of multi-dosing from the same product vial after storage. The impossibility to re-use leftovers today is contributing to an unnecessary and significant financial waste. Methods: A forced degradation study of cabazitaxel was performed under different conditions to produce degradation products. Acidic, basic, oxidation, heat, and ultraviolet (UV) light conditions were tested. The method to determine the stability was developed so that potential degradation products would be shown in the UV spectra after separation from cabazitaxel with a C18 column in a high-performance liquid chromatography (HPLC) system. The only degradation product occurring during storage in room temperature and ambient light was identified by accurate mass Orbitrap Mass Spectrometry. Results/Conclusion: A stability-indicating method for cabazitaxel (Jevtana ®) concentrate-solvent mixture has been developed. We demonstrated that this method can be applied to stability studies with the purpose of multi-dosing cabazitaxel from a chemical/physical stability perspective within the tested period of time and conditions. As an addition, the only naturally occurring degradation product found has been identified and a degradation reaction has been suggested.

A simple, accurate, reproducible and specific stability-indicating RP-HPLC method was developed for estimation of ethionamide in tablets. Ethionamide was exposed to acid, alkali and neutral hydrolysis at elevated temperatures, to thermolytic degradation, peroxide-mediated oxidation at room temperature in dark and to photolytic degradation. The drug was found stable to thermolytic and photolytic conditions and to neutral hydrolysis. However, substantial degradation was obtained in acid and alkali hydrolysis and complete degradation in peroxide-medicated oxidation. Similar degradation behavior was observed when ethionamide tablets were exposed to the mentioned forced degradation conditions. The method showed adequate resolution of drug from its potential degradation products on C18 (250 × 4.6 mm, 5µ) column using mobile phase of methanol: water (50: 50 % V/V) at 1 mL/min. The drug and its potential degradation products were detected at 290 nm. The method was validated as per the ICH Q2(R1) guidelines. The enrichment of the alkali degradation product was performed and isolated by preparative TLC and further confirmed by NMR and IR spectroscopy.

The present work was the development of a simple, efficient, and reproducible stability-indicating reverse-phase high performance liquid chromatographic (RP-HPLC) method for simultaneous determination enrofloxacin (EFX) and its degradation products including ethylenediamine impurity, desfluoro impurity, ciprofloxacin impurity, chloro impurity, fluoroquinolonic acid impurity, and decarboxylated impurity in tablet dosage forms. The separation of EFX and its degradation products in tablets was carried out on Kromasil C-18(250×4.6 mm, 5 μm) column using 0.1% (v/v) TEA in 10 mM KH2PO4(pH 2.5) buffer and methanol by linear gradient program. Flow rate was 1.0 mL min−1with a column temperature of 35°C and detection wavelength was carried out at 278 nm and 254 nm. The forced degradation studies were performed on EFX tablets under acidic, basic, oxidation, thermal, humidity, and photolytic conditions. The degraded products were well resolved from the main active drug and also from known impurities within 65 minutes. The method was validated in terms of specificity, linearity, LOD, LOQ, accuracy, precision, and robustness as per ICH guidelines. The results obtained from the validation experiments prove that the developed method is a stability-indicating method and suitable for routine analysis.

The present work describes the development of a sensitive and economic stability indicating high performance liquid chromatographic (HPLC) method for the determination of cefpodoxime proxetil (CP) as bulk drug and as pharmaceutical formulation. Both R and S isomers of the drug were separated using Phenomenex ( mm, 5 μm particle size) ODS column with a flow rate of 1 mL min−1 and an SPD 20 A UV detector to monitor the eluate at 252 nm. The isocratic method used a mobile phase consisting of methanol and phosphate buffer of pH 4.0 in the ratio 65 : 35. The linear regression analysis data for the calibration plots showed good linear relationship with in the working concentration range of 5–100 μg mL−1. The LOD and LOQ were 53 and 160 ng mL−1, respectively. CP was subjected to stress degradation using acid, alkali, hydrogen peroxide, dry heat, wet heat, and UV light. The standard drug peaks were well resolved from the degradation products’ peaks with significantly different retention time (Rt), and the resolution factor for the R and S isomers of CP was found to be greater than 2.

The Stability

The purpose of this study was to develop and validate a fast HPLC stability-indicating method for simultaneously quantifying the four main isoflavones in Trifolium pratense. Validation procedures followed the ICH requirements for complex matrices. The stability-indicating tests were performed by exposing the isoflavones to conditions of forced degradation and further analysis for verifying the formation of degradation products and their possible interferences in the HPLC analysis. The major isoflavones of Trifolium pratense proved to be stable against acid and oxidative media, thermodegradation, and photodegradation. However, they proved to be unstable in alkaline media, even for short periods of exposure like 2h. In this condition, in addition to the peaks corresponding to isoflavones, the HPLC analysis showed the presence of three additional peaks which were eluted at different retention times to the reference substances, without interfering in the quantification of the four analytes of interest, formononetin, biochanin A, daidzein and genistein. The method was validated following ICH guidelines showing to be specific, linear, precise, accurate, and robust.This first report concerning a stability-indicating method revealed that the proposed HPLC method reliably quantify the isoflavones and separate them from the degradation products in a short time of analysis.

Darunavir Ethanolate

Chemical and physical degradation of drugs may result in altered therapeutic efficacy and even toxic effects. Therefore, the aim of this work was to study the stability of darunavir and to develop and validate a liquid chromatography (LC) method to determine darunavir in raw material and tablets in the presence of degradation products. The novel method showed to be linear from 6.0 to 21.0 μg/mL, with high precision (CV < 2%) and accuracy (recuperation of 99.64%). It is simple and reliable, free of placebo interferences. The robustness of the method was evaluated by a factorial design using seven different parameters. Forced degradation study was done under alkaline, acidic, and oxidative stress at ambient temperature and by heating. The LC method was able to quantify and separate darunavir and its degradation products. Darunavir showed to be unstable under alkaline, acid, and oxidative conditions. The novelty of this study is understanding the factors that affect darunavir ethanolate stability in tablets, which is the first step to unravel the path to know the degradation products. The novel stability-indicating method can be used to monitor the drug and the main degradation products in low concentrations in which there is linearity.

An accurate, sensitive, precise and stability-indicating reversed phase high performance liquid chromatographic (RP-HPLC) method for the analysis of clopidogrel bisulfate was developed and validated. The chromatographic conditions comprised of a reversible phase C18 column (250 × 4.6 mm, 5 μm) with a mobile phase consisting of a mixture of 50 mM potassium di-hydrogen phosphate and acetonitrile in the ratio of 75:25 at pH 3.0 adjusted with phosphoric acid. The flow rate was 1ml/min, the detection was carried out at 247 nm and the retention time of clopidogrel was 6.5 min. Clopidogrel was subjected to acid and alkali hydrolysis, oxidation and photodegradation. The method was validated for accuracy, precision and robustness. The results indicate that the drugs are susceptible to degradation in different conditions. All the peaks of degraded products were resolved from the active pharmaceutical ingredient with significant different retention times. As the method could effectively separate the drug from its degradation products, it could be employed as a stability-indicating method.

A selective, precise and stability-indicating, modified high performance liquid chromatographic method for the analysis of sodium picosulfate both as a bulk drug and in formulations was developed and validated. As the method could effectively separate the drug from its degradation product, it can be employed as a stability-indicating one. The chromatographic separation was achieved on a ZORBAX Eclipse XDB C-18 analytical column. The mobile phase consisted of phosphate buffer (pH 7):acetonitrile (85:15 v/v). The absorbance was monitored with a DAD detector at 263 nm. The flow rate was 1.5 mL min-1. Statistical analysis proved the method is repeatable, selective, and accurate for estimation of sodium picosulfate in the presence its degradation product. Forced degradation studies were performed on bulk sample of sodium picosulfate using heat (25, 40, 60 and 80 ?C) and oxidation (0.1, 0.5 and 1% v/v hydrogen peroxide). The proposed method was successfully applied, with excellent recovery, to the analysis of a pharmaceutical formulation (Sodium picosulfate, Zdravlje-Actavis, Serbia).
