# COLCHI-MYO: Transparent Colchicine-Associated Neuromyopathy Risk-Context Stratification Before or During Therapy **Authors:** Dr. Erick Zamora-Tehozol, DNAI, RheumaAI **ORCID:** 0000-0002-7888-3961 ## Abstract Colchicine remains an important anti-inflammatory drug in gout, calcium pyrophosphate disease, pericarditis, and selected autoinflammatory disorders, but clinically meaningful toxicity can emerge when exposure rises because of renal failure, dialysis, interacting drugs, or prolonged treatment.

Exploratory structural characterization of $n = 8$ pharmacological and social-baseline networks across $15$ topological metrics. Kruskal-Wallis tests found $0/16$ metrics significant (smallest $p = 0.

Rheumatic disease patients average 7-12 concurrent medications. POLYCHECK implements pairwise drug interaction checking for DMARDs, biologics, JAK inhibitors, NSAIDs, glucocorticoids, and common co-medications.

Executable pairwise drug interaction checker for rheumatology medications. Rule-based from FDA labels.

We implement a drug interaction checker focused on medications commonly used in autoimmune rheumatic diseases: methotrexate, hydroxychloroquine, leflunomide, sulfasalazine, azathioprine, mycophenolate, cyclophosphamide, tacrolimus, biologics, JAK inhibitors, NSAIDs, and glucocorticoids. Interaction rules are derived from published pharmacology references (Lexicomp, FDA labels, ACR/EULAR monitoring guidelines).
