Sodium nitroprusside (SNP), sold under the brand name Nitropress among others, is a medication used to lower blood pressure. [3] This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding. [3]
Sodium nitroprusside, a medicinally significant metal nitrosyl-pentacyanoferrate (Fe-III) compound, used to treat hypertension. [1] Metal nitrosyl complexes are complexes that contain nitric oxide, NO, bonded to a transition metal. [2] Many kinds of nitrosyl complexes are known, which vary both in structure and coligand.
Whether a specific drug is useful or harmful under heart failure and myocardial infarction depends on its speed of action: Fast acting substances such as glyceryl trinitrate and nitroprusside can be helpful for controlling blood pressure and consequently the amount of blood the heart has to pump, if the application is monitored continuously.
A solution of 2% sodium carbonate in water (solution B) [4] Separate storage of the aldehyde and base are necessary to prevent aldol polymerisation of the aldehyde. When exposed to an amine, reaction with acetaldehyde produces the enamine , which subsequently reacts with sodium nitroprusside to the imine .
The French chemist Z. Roussin [5] first prepared this salt while investigating reactions between nitroprusside ion ([Fe(CN) 5 NO] 2−) and sulfur. [6] The salt can be prepared by the reaction of sulfide salts with iron nitrosyl halides: [7] Fe 2 I 2 (NO) 4 + 2Li 2 S → Li 2 Fe 2 S 2 (NO) 4 + 2LiI

Sodium nitroprusside was previously the first-line choice due to its rapid onset, although now it is less commonly used due to side effects, drastic drops in blood pressure, and cyanide toxicity. Sodium nitroprusside is also contraindicated in patients with myocardial infarction, due to coronary steal. [ 9 ]
The cyanide compound sodium nitroprusside is used mainly in clinical chemistry to measure urine ketone bodies mainly as a follow-up to diabetic patients. On occasion, it is used in emergency medical situations to produce a rapid decrease in blood pressure in humans; it is also used as a vasodilator in vascular research.
