Sodium nitroprusside is disodium pentacyanonitrosylferrate(2-) dihydrate, a hypotensive agent whose structural formula is whose molecular formula is Na 2 [Fe(CN) 5 NO] • 2H 2 O, and whose molecular weight is 297.95. Dry sodium nitroprusside USP is a reddish-brown crystals or powder, soluble in water. In an aqueous solution infused intravenously, sodium nitroprusside is a rapid-acting vasodilator, active on both arteries and veins. Sodium nitroprusside solution is rapidly degraded by trace contaminants, often with resulting color changes. (See DOSAGE AND ADMINISTRATION section.) The solution is also sensitive to certain wavelengths of light, and it must be protected from light in clinical use. Sodium Nitroprusside Injection is sterile, reddish brown color solution, essentially free from visible particles and is available as: 50 mg Vial – Each 2 mL vial contains the equivalent of 50 mg sodium nitroprusside USP in water for injection.
