Chronic inflammatory rheumatic disorders impose substantial burdens on patients, clinicians, and healthcare systems worldwide. As a novel disease‑modifying antirheumatic drug, Iguratimod exhibits unique anti‑inflammatory, immunomodulatory, and bone‑protective properties, providing a new therapeutic option for rheumatoid arthritis and related conditions.

Every day, in operating rooms across the globe, anesthesiologists perform a precisely choreographed sequence. The patient receives an induction agent to lose consciousness. Then comes a neuromuscular blocking agent—a drug that paralyzes skeletal muscles, including those required for breathing. The anesthesiologist inserts an endotracheal tube, connects a ventilator, and the surgery proceeds. Without the neuromuscular blocker, intubation would be impossible in a conscious or lightly sedated patient. Without the reversal agent, paralysis would outlast the procedure.
