This study aimed to develop a reliable stability-indicating method (SIM) for amoxicillin 500 mg capsules (DP-drug product). A literature review addressing amoxicillin (AMX; DS-drug substance) forced degradation studies and the existing SIMs was conducted to verify the most significant outcomes. Subsequently, the forced degradation of DP and DS was carried out following the Brazilian Health Surveillance Agency (ANVISA) guidelines, including thermal degradation (dry and wet heat), acidic and alkaline hydrolyses, hydrogen peroxide oxidation, reaction with copper, and photodegradation. Both DS and DP were more susceptible to 0.015 M NaOH, resulting in approximately 50% degradation. AMX DS and DP were not significantly photodegraded, but some degradation products (PDegs) showed susceptibility to light exposure. Thermodegraded samples showing ≥ 10% degradation exhibited modified profiles in thermogravimetric (TG) and differential scanning calorimetric (DSC) analyses. The X-ray powder diffraction patterns (XRPD) of DS samples exposed to dry and wet heat displayed complete amorphization of AMX, attesting to the occurrence of physical degradation concomitantly with chemical degradation, which can alter the drug’s bioavailability. In contrast, the thermodegraded DP samples exhibited intact AMX crystals interspersed with the amorphous form, perhaps partly protected by the excipient. The validated SIM was able to detect and quantify about 80 PDegs.

Stability Indicating Method

Abstract Background Water-soluble vitamins are often included simultaneously in pharmaceutical formulations as food complements or in parenteral nutrition mixtures. Given their sensitivity to heat, light or pH variations, it is important to study their stability using validated stability indicating methods. We thus aimed to validate a liquid chromatography (LC) stability-indicating method for the simultaneous quantification of 5 water-soluble vitamins. Methods We analyzed four water-soluble B vitamins (nicotinamide, pyridoxine, folic acid, cyanocobalamin) and ascorbic acid using a LC method with diode array detector. They were separated on a C18 stationary phase under gradient elution of solvent A [0.2 % of metaphosphoric acid in water and acetonitrile 98:2] and solvent B (100 % acetonitrile). All vitamins were subjected to forced degradation conditions and we showed that the obtained degradation products didn’t interfere with the vitamins. Results The method allows the separation of the 5 water-soluble vitamins in a 30 minute run without any interference from the breakdown products obtained with acid/alkaline solutions, hydrogen peroxide, temperature and light. It meets all the qualitative and quantitative criteria for validation with an acceptable accuracy and good linearity. Conclusions This stability-indicating method can be used for carrying out stability studies of water-soluble vitamins in pharmaceutical preparations.

Abstract This paper describes the development of a stability-indicating RP-HPLC method for the determination of atomoxetine hydrochloride (ATX) in the presence of its degradation products generated from forced decomposition studies. The drug substance was subjected to stress conditions of acid, base, oxidation, wet heat, dry heat, and photodegradation. In stability tests, the drug was susceptible to acid, base, oxidation, and dry and wet heat degradation. It was found to be stable under the photolytic conditions tested. The drug was successfully separated from the degradation products formed under stress conditions on a Phenomenex C18 column (250 4.6 mm id, 5 m particle size) by using acetonitrilemethanol0.032 M ammonium acetate (55 + 05 + 40, v/v/v) as the mobile phase at 1.0 mL/min and 40C. Photodiode array detection at 275 nm was used for quantitation after RP-HPLC over the concentration range of 0.55 g/mL with a mean recovery of 100.8 0.4 for ATX. Statistical analysis demonstrated that the method is repeatable, specific, and accurate for the estimation of ATX. Because the method effectively separates the drug from its degradation products, it can be used as a stability-indicating method.

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 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.

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.

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.
