|---|---|
| Pharmacology: | Nitroprusside a powerful vasodilator relaxes the vascular smooth muscle and produce consequent dilatation of peripheral arteries and veins. Other smooth muscle (e.g., uterus, duodenum) is not affected. Sodium nitroprusside is more active on veins than on arteries. |
| Mechanism of Action: |
One molecule of sodium nitroprusside is metabolized by combination with hemoglobin to produce one molecule of cyanmethemoglobin and four CN- ions; methemoglobin, obtained from hemoglobin, can sequester cyanide as cyanmethemoglobin; thiosulfate reacts with cyanide to produce thiocyanate; thiocyanate is eliminated in the urine; cyanide not otherwise ...

| Biotransformation: | Metabolized by reaction with hemoglobin to produce cyanmethemoglobin and cynide ions |
| Route of elimination: | One molecule of sodium nitroprusside is metabolized by combination with hemoglobin to produce one molecule of cyanmethemoglobin and four CN¯ ions, thiosulfate reacts with cyanide to produce thiocyanate, thiocyanate is eliminated in the urine. |
| Half Life: | Approximately 2 minutes |
| Toxicity: | Overdosage of nitroprusside can be manifested as excessive hypotension or cyanide toxicity or as thiocyanate toxicity. The acute intravenous mean lethal doses (LD50) of nitroprusside in rabbits, dogs, mice, and rats are 2.8, 5.0, 8.4, and 11.2 mg/kg, respectively. |
| Affected organisms: | Humans and other mammals |
