silver protein silver made colloidal by the presence of, or combination with, protein; an active germicide with a local irritant and astringent effect.
silver sulfadiazine the silver derivative of sulfadiazine, having bactericidal activity against many gram-positive and gram-negative organisms, as well as being effective against yeasts; used as a topical antiinfective for the prevention and treatment of wound sepsis in patients with second and third degree burns.
toughened silver nitrate a mixture of silver nitrate with hydrochloric acid, sodium chloride, or potassium nitrate, occurring as white crystalline masses molded into pencils or cones; a convenient means of applying silver nitrate locally.

sil·'ver ni·trate

an antiseptic and astringent; formerly used externally, in solution, in the prevention of ophthalmia neonatorum; also used in the special staining of the nervous system, spirochetes, reticular fibers, Golgi apparatus, nucleolar organizer region, and calcium.

silver nitrate

n.
A poisonous colorless crystalline compound, AgNO3, that becomes grayish black when exposed to light in the presence of organic matter and is used in manufacturing photographic film, silvering mirrors, dyeing hair, plating silver, and in medicine as a cautery and antiseptic.

silver nitrate (AgNO3)

a topical antiseptic.
indications A 1% solution was traditionally prescribed for the prevention of gonococcal ophthalmia in newborns, but povidone iodine is now usually used because it is less expensive and has a broader spectrum of action. Stronger concentrations can also be used on wet dressings for cauterizing wounds, removal of granulation tissue and warts, and prophylaxis following burns.
contraindication Known sensitivity to this drug prohibits its use.
adverse effects Among the more serious adverse effects are severe local inflammation, burns, and argyria, and staining.
