🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine provides hydroxocobalamin, which is converted in the body to the active coenzyme forms of vitamin B12, methylcobalamin and adenosylcobalamin. These coenzymes are essential for two important reactions: the conversion of methylmalonyl-CoA to succinyl-CoA and the conversion of homocysteine to methionine. By supporting these reactions, hydroxocobalamin helps maintain normal nerve function, red blood cell formation, and DNA synthesis. In cyanide poisoning, hydroxocobalamin binds directly to cyanide ions to form cyanocobalamin, which is then safely excreted in the urine.
Mechanism Steps
💡 How to Take nuroxymin 1000mcg injection
Strength: This medicine is available as a 1000 microgram (1 mg) injection in a single-use vial or ampoule.
Dosage Information
| Adult Dosage | The dose of this medicine is individualized by a qualified clinician based on the indication, severity of deficiency, age, weight, and kidney function. For vitamin B12 deficiency, a common regimen is 1000 micrograms intramuscularly or intravenously once daily for several days, followed by weekly injections, and then monthly maintenance. For cyanide poisoning, the dose is much higher and is determined by the emergency team. Do not self-administer; this medicine must be given by a healthcare professional. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may receive the same doses as adults, but their kidney function should be checked before treatment. Your doctor will adjust the dose if needed. |
| Renal Impairment | Patients with severe kidney disease may need a lower dose or less frequent injections. Your doctor will monitor your kidney function and adjust the dose accordingly. |
| Hepatic Impairment | No dose adjustment is needed for patients with liver disease, as this medicine is not metabolized by the liver. |
| Maximum Daily Dose | The maximum daily dose depends on the indication. For vitamin B12 deficiency, the usual maximum is 1000 micrograms per day. For cyanide poisoning, much higher doses may be used under medical supervision. Always follow your doctor's instructions. |
