Silver nitrate has historically been used as what type of agent in medicine?

• A. Antibiotic
• B. Antiseptic and cauterizing agent
• C. Analgesic
• D. Anesthetic

Answer: (B)

Silver nitrate has historically been used as an antiseptic and a cauterizing agent. Its antimicrobial effect comes from silver ions, which disrupt bacterial enzymes and interfere with essential cellular processes, providing topical antisepsis. At the same time, the concentrated chemical is caustic to tissue, causing protein coagulation and tissue necrosis that produces a controlled burn—this chemical cauterization helps stop minor bleeding and removes or dehydrates diseased tissue. Because of these dual properties, it was widely used in medicine for prevention of infection and for cauterization. It is not an antibiotic, since antibiotics are targeted agents produced by organisms or designed to inhibit specific bacterial processes; it is not primarily an analgesic or anesthetic, since its main roles are antisepsis and tissue cauterization, not pain relief or sensation loss.
