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\u2010friendly 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\u2010wavelength (DWL) methods were developed, providing linear ranges of 2\u201325\u2009\u00b5g\/mL for meloxicam and 10\u2013170\u2009\u00b5g\/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.<\/jats:p>","DOI":"10.1002\/ardp.70323","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T11:07:56Z","timestamp":1787569676000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["First UV\u2010Based Strategies Integrating Whiteness, Greenness, and Blueness Appraisals for Estimating Meloxicam and Tramadol Concurrently in Their Veterinary Mixture"],"prefix":"10.1002","volume":"359","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7874-6334","authenticated-orcid":false,"given":"Ahmed R.","family":"Mohamed","sequence":"first","affiliation":[{"name":"Pharmaceutical Analytical Chemistry Department, Faculty of Pharmacy Egyptian Russian University Badr Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4366-6200","authenticated-orcid":false,"given":"Eman","family":"Darweish","sequence":"additional","affiliation":[{"name":"Pharmaceutical Analytical Chemistry Department, Faculty of Pharmacy Egyptian Russian University Badr Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8560-8944","authenticated-orcid":false,"given":"Sabry M.","family":"Attia","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, College of Pharmacy King Saud University Riyadh Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanveer","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Molecular and Integrative Physiology University of Illinois at Urbana\u2010Champaign Urbana Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8127-3785","authenticated-orcid":false,"given":"Youstina M.","family":"Metias","sequence":"additional","affiliation":[{"name":"Pharmaceutical Analytical Chemistry Department, Faculty of Pharmacy Zagazig University Zagazig Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,24]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.13566"},{"key":"e_1_2_9_3_1","unstructured":"United States Pharmacopeial Convention The United States Pharmacopeia and the National Formulary (USP 36\u2013NF 31)(United States Pharmacopeial Convention 2013)."},{"key":"e_1_2_9_4_1","volume-title":"British Pharmacopoeia","author":"British Pharmacopoeia Commission","year":"2022"},{"key":"e_1_2_9_5_1","volume-title":"Martindale: The Complete Drug Reference","author":"Sweetman S.
