J Pharm Sci 2024:S0022-3549(24)00133-3. [PMID: 38608727 DOI: 10.1016/j.xphs.2024.04.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 04/05/2024] [Accepted: 04/05/2024] [Indexed: 04/14/2024]
Abstract
The preparation of amorphous solid dispersions (ASDs) represents a promising strategy for addressing the solubility limitations of poorly soluble drugs, facilitating enhanced oral absorption. Acidic polymers such as cellulose acetate phthalate (CAP) and hydroxypropyl methylcellulose phthalate (HPMCP) have emerged as effective carriers for ASDs. Although the hydrolytic degradation of these polymers has been documented, its impact on the stability of ASDs has not been systematically investigated. This research aimed to explore the potential hydrolysis of CAP and HPMCP and how it influences the stability of ASDs containing ketoconazole (KTZ), at drug loadings of 10 % and 50 %. Our study utilized thermal analysis, infrared spectroscopy, and evaluations of physical and chemical stability. The results revealed that although KTZ remained physically stable in all ASDs over 60 days under various stability conditions, the emergence of crystalline phthalic acid (PA), a byproduct of polymer hydrolysis, was observed at elevated temperatures and relative humidity levels. The acidic microenvironment fostered by the release of PA further catalyzed drug chemical degradation. This study underscores the susceptibility of CAP and HPMCP to hydrolytic degradation, highlighting the inherent risk of PA-induced drug degradation, particularly for acid-labile compounds. These insights into the understanding of polymer hydrolysis in ASDs pave the way for the development of targeted approaches to safeguard drug stability and optimize pharmaceutical formulations for enhanced bioavailability, efficacy, and safety.

Abstract
Liquid chromatography interfaced with mass spectroscopy (LC-MS) is a sensitive and effective analytical method that combines high-resolution separation as well as specific mass detection of impurities in formulated products and as well as in active pharmaceutical ingredient (API). In this study, LC-MS/MS was used to determine impurities formed during the stability period of Efinaconazole (EFZ, a triazole antifungal agent). The method was validated for its assay parameters such as specificity, linearity, accuracy, precision and also for solution stability. The calibration curve was found to be linear for the concentration range from 0.5 μg/mL to 30 μg/mL. A thorough investigation was performed by exposing Efinaconazole (1 mg/mL) to various stress conditions such as hydrolysis (acid and alkaline), oxidation, photolysis and temperature at various time intervals to achieve 10% degradation. The impurities formed during forced degradation were separated using high-performance liquid chromatography later it was identified using LC-MS/MS technique. The obtained results showed that EFZ is prone to oxidation when exposed to a 3% aqueous medium of hydrogen peroxide solution and quite stable in all the remaining stress conditions for a longer period.

Abstract
Related substances in pharmaceutical formulations are associated with their safety, efficacy and stability. However, there is no overall study already published on the assessment of related substances in the Compound Ketoconazole and Clobetasol Propionate Cream. In this work, a reliable HPLC-TOF-MS qualitative method was developed for the analysis of related substances in this preparation with a quick and easy extraction procedure. Besides the active pharmaceutical ingredients, two compounds named ketoconazole impurity B′ optical isomer and ketoconazole impurity E were identified. Furthermore, a new HPLC method for qualitative and quantitative assessment on related substances and degradation products, which were found in the stability test, was established and validated. The single standard to determine multi-components method was applied in the quantitative analysis, which was an effective way for reducing cost and improving accuracy. This study can provide a creative idea for routine analysis of quality control of the Compound Ketoconazole and Clobetasol Propionate Cream.

Abstract
The purpose of the study was to evaluate organogel nanoparticles as a drug delivery system by investigating their stability, according to the formulation strategy, and their release profile. The gelled nanoparticles were prepared by hot emulsification (above the gelation temperature) of an organogel in water, and cooling at room temperature. In the first step, we used DLS and DSC to select the most suitable formulations by optimizing the proportion of ingredients (HSA, PVA, castor oil) to obtain particles of the smallest size and greatest stability. Then, two lipophilic drug models, indomethacin and ketoconazole were entrapped in the nanoparticles made of castor oil gelled by 12-hydroxystearic acid. Thermal studies (DSC) confirmed that there was no significant alteration of gelling due to the entrapped drugs, even at 3% w/w. Very stable dispersions were obtained (>3 months), with gelled oil nanoparticles presenting a mean diameter between 250 and 300 nm. High encapsulation efficiency (>98%) was measured for indomethacin and ketoconazole. The release profile determined by in vitro dialysis showed an immediate release of the drug from the organogel nanoparticles, due to rapid diffusion. The study demonstrates the interest of these gelled oil nanoparticles for the encapsulation and the delivery of lipophilic active compounds.

Abstract
In this work, a stability-indicating high-performance liquid chromatography (HPLC) method was developed and validated for the simultaneous analysis of ketoconazole (KCZ) and beauvericin (BEA) as well as their degradation products in the combination tablets. KCZ is a synthetic broad-spectrum antifungal agent with the risk of hepatoxicity. However, it was found that the combined use of KCZ and BEA in their low dose had not only maintained the antifungal activity of KCZ but also significantly reduced the liver toxicity. The method development was started from forced degradation studies including acidic, basic, oxidative, thermal and photolytic degradations in the solution mixtures of KCZ and BEA. The forced degradation study results indicate that hydrolysis and oxidation were the major degradation pathways for KCZ while BEA mainly decomposed under basic hydrolytic condition. The newly developed HPLC method was validated according to the International Conference on Harmonization (ICH) guidelines with respect to specificity, linearity, precision, accuracy, limits of detection and quantification and robustness. The method validation results indicate that the new HPLC method could be successfully applied in the simultaneous detection and quantitation of KCZ and BEA and their degradation products. For example, the accuracy and the precision of the method were determined by a recovery study at 80, 100 and 120% of the tablet dosage levels. The recovery was found to be 99.6-100.2 for both analytes with a relative standard deviation of no more than 1.2% (n = 5) at any concentration level. This new method can be used for further development of various KCZ and BEA combination drug products.

Abstract
A simple, specific, precise, and accurate RP-HPLC method has been developed and validated for simultaneous estimation of Methylparaben (MP), Ketoconazole (KT), and Mometasone Furoate (MF) topical pharmaceutical dosage formulation. The separation was achieved by Waters X Terra C18 column using mobile phase consisting of buffer (triethyl amine in water, pH adjusted to 6.5 with glacial acetic acid)-acetonitrile (40 : 60, v/v) at a flow rate of 1.5 mL/min and detection at 250 nm. The method showed linearity with correlation coefficient <0.9999 over the range of 0.12–15.2 μg/mL, 0.67–149.4 μg/mL, and 0.42–7.6 μg/mL for MP, KT, and MF, respectively. The mean recoveries were found to be in the range of 99.9–101.1% for all the components. The method was validated as per the ICH guidelines for linearity, limit of detection, limit of quantification, accuracy, precision, robustness and solution stability. Stability indicating capability of the developed method was established by analyzing forced degradation of samples in which spectral purity of MP, KT, and MF along with separation of degradation products from analytes peak was achieved. The method can be successfully applied for routine analysis of quantitative determination of MP, KT, and MF in pharmaceutical dosage form.
