Abstract

Gentamicin is an antibiotic with a narrow therapeutic index that necessitates therapeutic drug monitoring (TDM) to enhance efficacy and reduce toxicity. The goal of this study was to a simple, sensitive, and reliable LC-MS/MS method for measuring gentamicin in human plasma with a key novelty being the comprehensive assessment and documentation of measurement uncertainty integrated into the method validation process. The method used a Sciex QQQ 4500 LC-MS/MS system equipped with a C18 column, 5 x 20 mm, 4 µm Fusion-RP 80 Å, and operated in multiple reaction monitoring (MRM) mode, employing amikacin as the internal standard. Method validation was conducted following ICH M10 (2022) guidelines, encompassing parameters of selectivity, linearity, accuracy, precision, stability, dilution integrity, and carry-over. The calibration curve showed good linearity (r² = 0.990–0.996) over the range of 100–5000 ng/mL, with a lower limit of quantification (LLOQ) of 100 ng/mL. Across all concentration levels, accuracy (within ±15%; ±20% at LLOQ) and precision (≤15% CV; ≤20% at LLOQ) met the acceptance criteria. Short term stability experiments indicated that the samples maintained enough rigidity for various handling and storage method. We used EURACHEM and JCGM GUM guidelines to figure out the measurement uncertainty. The standard error of the slope (SEm) was the biggest factor. The total uncertainty was found to be 0.27 ng/mL, which means that the expanded uncertainty is ±0.55 ng/mL with 95% confidence. The validated method is strong and dependable, which makes it good for use in clinical settings for gentamicin TDM.

Abstract

Diabetic wounds are a major clinical challenge due to delayed healing and increased complication risks. Ethanol extract of avocado leaves (Persea americana Mill.) has previously shown promise in enhancing tissue regeneration in diabetic wounds, but its potential in gel form remains untested. This study aimed to develop an avocado leaf ethanol extract-based gel and evaluate its woundhealing potential in diabetic mice. Avocado leaves were extracted using 70% ethanol and formulated into a gel, which was evaluated for physical properties and topical suitability. Diabetic mice were divided into five groups: normal control, negative control (gel base), positive control (bioplacenton), and two treatment groups (5% and 10% gel). Diabetes was induced using alloxan (150 mg/kg BW), followed by wound induction and treatment. Wound healing was assessed through visual assessment, wound diameter reduction, and healing duration. Statistical analysis was performed using one-way ANOVA with a 95% confidence level. Results showed the gel meets physical properties (pH test, organoleptic test, homogeneity test, spreadability test) and significantly improved wound healing in diabetic mice. The 5% gel demonstrated wound-healing activity due to bioactive compounds such as saponins, tannins, alkaloids, and flavonoids. Further analysis is needed to identify the specific components responsible for the healing effects, highlighting the gel’s potential for diabetic wound treatment.

Abstract

Black rice and sprouted soybean (BRiSS) can be formulated into a healthy drink BRiSS. The safety of this novel combination must be rigorously tested. Therefore, this study was designed to conduct a comprehensive acute toxicity test of the healthy drink flavylium anthocyanins from black rice (Oryza sativa L. indica) pigmented polyphenols from soybean sprouts (Glycine max L.). The black rice was extracted with a 96% ethanol solution in 3% citric acid. The pigmentation process was achieved by adding hydroxyl groups from soybean polyphenols. The active material was mixed with 20% maltodextrin, shaken, poured into a pan, and dried with a cabinet dryer (60° C). The mixture was stirred with 0.3% sodium, 0.1% citric acid, 50% active ingredients, 5% sucrose as a sweetener, 0.05% sodium benzoate, and water, 100 ml. The five groups of male Wistar rats were acclimatized. Group 1 was a control, and groups 2, 3, 4, and 5 were sequentially treated with a healthy drink containing extract doses of 5, 50, 300, and 2000 mg/kg BW. The acute toxicity test results at 30 minutes, 3 to 24 hours, day 3, and day 14 were written on the acute toxicity test clinical symptom observation sheet. All test animals, including both the control and test groups with various dosage variations, did not exhibit changes in skin, fur, eyes, behavior, respiratory systems, and did not experience weight loss, seizures, tremors, lethargy, or diarrhea. The limitation was that the macropathology examination of internal organs (kidneys, liver, heart, brain, stomach, intestines, pancreas) was not performed. Not all animals have mortality in a 5-3000 (mg/kg BW) extract dose.

Abstract

Fenofibrate acid is a fibrate drug with high permeability but low water solubility, resulting in limited bioavailability. Solid dispersion using hydrophilic carriers is one strategy to increase solubility. The objective of this study was to improve the solubility of fenofibric acid by converting it into a solid dispersion system using PEG 6000 as a carrier. Preparation of solid dispersion systems by the melting method. The fenofibric acid PEG 6000 weight ratios were F1 (1:1), F2 (1:3), and F5 (1:5). Physicochemical characterization of the solid dispersions included DSC, PXRD, FTIR, and SEM tests, as well as dissolution and bioavailability tests with the determination of pharmacokinetic parameters. Characterization results show that fenofibric acid with PEG 6000 as a carrier still exhibits a crystalline phase but with reduced intensity, resulting in increased solubility and dissolution rate. Dissolution test show that solid dispersion F3 (1:5) dissolves faster (78.7%) than pure fenofibric acid (53.2%). after 60 minutes. Pharmacokinetic parameter determination tests showed no significant difference between pure fenofibric acid and solid dispersion. Solid dispersion of fenofibric acid with PEG 6000 as a carrier can improve the physicochemical performance and dissolution rate of fenofibric acid but pharmacokinetic parameters did not differ significantly.

Abstract

Hydrogen peroxide (H₂O₂) is widely used as an oxidizing agent in hair cosmetic products, requiring reliable and validated analytical methods to ensure product safety and regulatory compliance. This study investigated the effect of column temperature and validated a high-performance liquid chromatography–photodiode array (HPLC–PDA) method for H₂O₂ determination in hair cosmetic formulations using triphenylphosphine (TPP) derivatization under tropical laboratory conditions. The triphenylphosphine oxide (TPPO) derivative exhibited a stable maximum absorbance at 222 nm within the concentration range of 20–120 ppm, which was selected as the detection wavelength. System suitability was evaluated at ambient temperature, 35, 40, 45, and 50 °C. Column temperatures between 40 and 50 °C fulfilled all system suitability and validation criteria, demonstrating acceptable efficiency, peak symmetry, retention time stability, and reproducibility. Among these conditions, 40 °C was selected as the optimum column temperature based on overall analytical performance and practical considerations. Method validation showed excellent linearity (correlation coefficient r ≥ 0.995; residual variance Vxo ≤ 5%), acceptable precision (%RSD ≤ 2%), and adequate sensitivity, expressed as limits of detection (LOD) and limits of quantification (LOQ). Accuracy evaluation using matrix-spiked samples yielded recoveries within the AOAC acceptance range (90–107%). Overall, the validated HPLC–PDA method at 40 °C with detection at 222 nm is robust and suitable for routine determination of H₂O₂ in hair cosmetic products under tropical conditions.
