主要用途
Tranexamic acid IV infusion is used off-label as an adjunctive therapy for moderate-to-severe melasma unresponsive to topical agents and sun protection. It inhibits plasmin-mediated melanocyte stimulation and UV-induced pigmentary responses. Typically administered at 250–500 mg IV twice weekly for 4–8 weeks under dermatologic supervision, with strict contraindication screening for thromboembolic risk.
正常值范围
Tranexamic acid is not a routinely measured endogenous biomarker; therefore, there is no established 'normal range' for serum tranexamic acid concentration in clinical practice. Therapeutic plasma concentrations during intravenous administration for dermatologic indications (e.g., melasma) are typically targeted between 5–15 µg/mL, but these are pharmacokinetic targets—not diagnostic reference intervals. No standardized reference range exists for routine clinical reporting.
偏低可能原因
Inadequate dosing or infusion rate, premature discontinuation of infusion, enhanced renal clearance (e.g., in young adults or patients with high GFR), poor IV absorption (rare, as it is administered intravenously), or assay interference leading to falsely low measurement (if quantified via HPLC or LC-MS/MS).
偏高可能原因
Excessive dosing or rapid infusion, concomitant use of nephrotoxic drugs impairing renal excretion, acute or chronic kidney injury (especially eGFR <30 mL/min), advanced age with reduced creatinine clearance, or analytical error (e.g., matrix interference in chromatographic assays).
