🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Colistimethate sodium is an inactive prodrug that is hydrolyzed in the body to colistin, which is a polycationic polypeptide antibiotic. Colistin binds to the lipid A portion of lipopolysaccharides on the outer membrane of Gram-negative bacteria. This binding displaces calcium and magnesium ions, destabilizing the membrane and increasing its permeability. The disruption leads to leakage of intracellular contents and rapid bacterial cell death. Colistin is bactericidal against many Gram-negative bacteria, including multidrug-resistant strains.
Mechanism Steps
💡 How to Take cricolist 3miu injection
Strength: Injection: 3 million cell units (approximately 100 mg colistimethate sodium) per vial.
Dosage Information
| Adult Dosage | The dose of this medicine is individualized by a qualified clinician based on the type and severity of infection, patient weight, and renal function. A typical adult dose is 2.5 to 5 mg/kg of colistin base activity per day, divided into 2 to 4 doses, but the exact regimen must be determined by the treating physician. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may have reduced renal function and require dose adjustment. Monitor renal function closely. |
| Renal Impairment | Dose adjustment is required in patients with renal impairment. The dose should be reduced based on creatinine clearance. Consult a clinician for specific dosing. |
| Hepatic Impairment | No specific dose adjustment is recommended for hepatic impairment, but monitor liver function. |
| Maximum Daily Dose | The maximum daily dose should not exceed the recommended dose determined by a qualified clinician based on renal function. Typically, the maximum daily dose is 5 mg/kg of colistin base activity. |

🤱 Lactation Safety
Colistimethate sodium is excreted in breast milk in small amounts. Consult your doctor before breastfeeding while on this medicine.
💊 Overdose Management
Overdose may cause severe nephrotoxicity and neurotoxicity. There is no specific antidote. Treatment is supportive and symptomatic. Hemodialysis may be considered to remove colistin in severe cases. Monitor renal and neurological function closely.
⏰ Missed Dose
If you miss a dose, contact your healthcare provider immediately. Do not double dose. Your healthcare provider will determine the best course of action based on your dosing schedule.
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. Inform your doctor about all other medicines you are taking, especially other antibiotics, pain relievers, or diuretics, as they may increase the risk of kidney damage. Your kidney function will be checked regularly through blood tests. Stay well hydrated unless your doctor advises otherwise. Report any new symptoms such as tingling, numbness, muscle weakness, or decreased urination immediately. Do not stop treatment early even if you feel better, as this can lead to resistant infections.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients are at higher risk of kidney damage. Dose adjustment based on renal function is crucial. Monitor closely for neurotoxicity.
🤰 Pregnancy Planning (TTC)
If you are planning pregnancy, consult your doctor before starting this medicine. It should be used during pregnancy only if clearly needed.
🏥 Post-Surgery Considerations
This medicine may be used to treat surgical site infections caused by resistant bacteria. Monitor renal function closely after surgery.
🦷 Dental Procedures
