Meloxicam (MXC), an NSAID, is frequently formulated with tramadol hydrochloride (TDH), a widely used opioid analgesic, for synergistic pain management. A comprehensive survey of the available literature revealed that no analytical method has yet been reported for the concurrent determination of meloxicam and tramadol. Therefore, this work introduces two facile and eco-friendly UV spectrophotometric methodologies for the simultaneous assay of meloxicam and tramadol in their pure forms and veterinary dosage forms. Due to the significant spectral overlap between meloxicam and tramadol, direct concurrent analysis is challenging. To resolve this spectral interference, Fourier deconvolution (FDC) and dual-wavelength (DWL) methods were developed, providing linear ranges of 2–25 µg/mL for meloxicam and 10–170 µg/mL for tramadol with satisfactory sensitivity. The proposed methods were validated according to ICH guidelines and statistically compared with the reported methods for the individual drugs using appropriate statistical tests. Furthermore, their environmental sustainability was comprehensively assessed using the AGREEprep metric, complemented by whiteness and practicality evaluations based on the RGB12 algorithm and the BAGI tool. The results demonstrate that the proposed UV methods are sustainable, sensitive, specific, and suitable for the routine simultaneous analysis of meloxicam and tramadol in veterinary dosage forms.</p></div>","PeriodicalId":128,"journal":{"name":"Archiv der Pharmazie","volume":"359 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148808028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review evaluates venom-derived peptides in breast cancer from a medicinal chemistry and translational drug development perspective. A structured narrative synthesis of the literature was conducted, covering preclinical and early translational studies of peptides derived from snakes, spiders, scorpions, and bees, with emphasis on structure–function relationships, mechanisms of action, and optimization strategies. Unlike previous reviews that primarily focus on individual venom sources, this work integrates mechanistic pharmacology with peptide engineering and translational constraints to provide a unified drug-development framework across breast cancer subtypes. Venom-derived peptides exert anticancer effects through ion channel modulation, apoptosis induction, cell cycle arrest, angiogenesis inhibition, membrane disruption, and immune modulation, with reported selectivity toward malignant cells in triple-negative, HER2-positive, and hormone receptor-positive models. Despite encouraging preclinical evidence, clinical translation is limited by instability, immunogenicity, poor pharmacokinetics, delivery barriers, and manufacturing challenges. Emerging advances in peptide engineering, nanodelivery systems, and artificial intelligence-assisted design offer promising strategies to improve pharmacological performance and drug-like properties.
