🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine contains colistimethate sodium, which is an inactive prodrug. After administration, it is hydrolyzed in the body to release colistin, the active antibiotic. Colistin is a polymyxin antibiotic that binds to the lipopolysaccharide component of the outer membrane of Gram-negative bacteria. This binding displaces calcium and magnesium ions, destabilizes the membrane, and increases its permeability. As a result, essential intracellular contents leak out, leading to rapid bacterial cell death. This mechanism is bactericidal and is effective against many multidrug-resistant Gram-negative bacteria.
Mechanism Steps
💡 How to Take guficol 2miu injection
Strength: This medicine is supplied as a sterile powder for injection containing colistimethate sodium equivalent to 2 million international units (IU) per vial. It is reconstituted with sterile water or saline before administration.
Dosage Information
| Adult Dosage | The dose of this medicine must be individualized by a qualified clinician based on the indication, severity of infection, patient's weight, kidney function, and susceptibility of the bacteria. For adults with normal kidney function, a common dose is 2.5 to 5 mg/kg per day of colistin base activity, divided into 2 to 4 doses, given intravenously. The 2 million IU strength corresponds to approximately 66.8 mg of colistimethate sodium. The exact dose and frequency will be determined by your doctor. Do not self-administer. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. The dose in children must be individualized based on weight, kidney function, and the specific infection. Use only under the supervision of a pediatric specialist. |
| Elderly Dosage | Elderly patients are at increased risk of kidney damage and neurotoxicity. The dose should be adjusted based on kidney function, which often declines with age. Close monitoring of kidney function and neurological status is required. Start with a lower dose and adjust as needed. |
| Renal Impairment | Dose adjustment is required in patients with renal impairment. The dose should be reduced based on creatinine clearance. For patients with creatinine clearance less than 50 mL/min, the dose and/or frequency should be adjusted. In severe renal impairment, the dose may need to be significantly reduced, and monitoring of plasma levels may be necessary. Consult a clinical pharmacist or nephrologist for precise dosing. |
| Hepatic Impairment | No specific dose adjustment is required for hepatic impairment alone. However, liver function should be monitored, and caution is advised in patients with severe liver disease. |
| Maximum Daily Dose | The maximum daily dose should not exceed the dose recommended by your doctor. In adults with normal kidney function, the maximum daily dose is typically 5 mg/kg of colistin base activity. Doses above this may increase the risk of toxicity. Do not exceed the prescribed dose. |

🤱 Lactation Safety
It is not known whether colistimethate sodium or colistin is excreted in human breast milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Consult your doctor for guidance.
💊 Overdose Management
Overdose of this medicine can cause severe kidney damage, neurotoxicity, and respiratory paralysis. There is no specific antidote. Treatment is supportive and symptomatic. If overdose is suspected, stop the infusion immediately and seek emergency medical attention. Hemodialysis may help remove colistin from the blood in patients with severe renal impairment. Monitor vital signs, kidney function, and neurological status closely.
⏰ Missed Dose
This medicine is given by a healthcare professional in a hospital setting, so missed doses are unlikely. If you miss a scheduled dose, inform your nurse or doctor immediately. Do not attempt to self-administer a double dose. The healthcare team will determine the appropriate action based on your dosing schedule and clinical condition.
Additional Safety Advice
This medicine must be given only by a healthcare professional in a hospital or clinic setting. Do not attempt to self-administer this injection. Inform your doctor about all your medical conditions, especially kidney disease, myasthenia gravis, or any nerve or muscle disorder. Tell your doctor about all medicines you are taking, including prescription, over-the-counter, and herbal products, because this medicine can interact with other drugs that affect the kidneys or nerves. Your kidney function, urine output, and neurological status will be monitored during treatment. Report any new tingling, numbness, muscle weakness, confusion, or decreased urination immediately. Do not stop treatment on your own; the duration of therapy will be decided by your doctor based on your infection and response to treatment.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients are at higher risk of kidney damage and nerve damage from this medicine. Kidney function often declines with age, so dose adjustment is frequently needed. Close monitoring of kidney function, neurological status, and hydration is essential. Elderly patients may also be more susceptible to drug interactions.
🤰 Pregnancy Planning (TTC)
