Tranexamic Acid Therapeutic Cheat Sheet
Tranexamic acid (TXA) is a synthetic lysine derivative that reversibly blocks the lysine-binding site on plasminogen, preventing conversion to plasmin. While originally developed as an antifibrinolytic agent to reduce bleeding, TXA has several downstream effects that make it useful in dermatology, particularly for pigmentary disorders, with emerging evidence in inflammatory disorders as well. TX …

Antihistamines, particularly second-generation histamine H1-receptor antagonists, are widely used in dermatology due to their antihistaminic activity and favorable safety profile characterized by minimal sedation compared with first-generation agents. They primarily act as peripheral H1-receptor antagonists, reducing histamine-mediated effects such as vasodilation, increased vascular permeability, …
