Kolject

Colistimethate Sodium, the active ingredient in Kolject, is a polymyxin antibiotic presented as a sterile solution for intravenous use. It treats infections caused by susceptible Gram‑negative bacteria, including Pseudomonas aeruginosa and Acinetobacter baumannii, in hospitalized patients.

GNH USA supplies Kolject as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Kolject (colistimethate sodium) is used to treat infections caused by Gram‑negative bacteria, targeting the bacterial outer membrane.

- Pseudomonas aeruginosa infections: effective therapy for severe hospital‑acquired infections. - Acinetobacter baumannii infections: used when isolates are susceptible to colistin. - Other susceptible Gram‑negative bacterial infections: provides an option for multidrug‑resistant organisms.

Kolject may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nephrotoxicity: reduced kidney function, elevated serum creatinine. - Neurotoxicity: paresthesia, dizziness, headache. - Nausea: mild gastrointestinal upset. - Vomiting: occasional episodes. - Diarrhea: loose stools. - Rash: mild skin irritation.

Serious or Rare Side Effects: - Acute renal failure: severe kidney injury requiring dialysis. - Neuromuscular blockade: respiratory muscle weakness, potentially leading to respiratory failure. - Anaphylaxis: severe allergic reaction with hypotension and airway compromise. - Seizures: rare neurological event. - Hematuria: blood in urine indicating renal damage. - Thrombocytopenia: low platelet count increasing bleeding risk.

Before initiating Kolject therapy, clinicians should consider several safety measures.

- Renal function monitoring: assess serum creatinine before and during therapy. - Neurotoxicity monitoring: watch for tingling, dizziness, or seizures. - Dose adjustment in renal impairment: reduce dose as needed based on clearance. - Avoid concomitant nephrotoxic drugs: limit use of aminoglycosides, NSAIDs, and loop diuretics. - Pregnancy and lactation: use only if benefits outweigh potential risks. - Store at 2‑8 °C: keep refrigerated, protect from light, do not freeze or shake.

Kolject can interact with several medications, requiring careful management.

Major Interactions (Avoid): - Aminoglycosides: additive nephrotoxicity. - Loop diuretics: increased risk of renal injury. - Neuromuscular blocking agents: enhanced neuromuscular blockade.

Moderate Interactions (Monitor Closely): - Vancomycin: potential additive nephrotoxicity. - Non‑steroidal anti‑inflammatory drugs (NSAIDs): increased renal risk. - Radiographic contrast media: heightened nephrotoxicity risk.
