🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 50S subunit of the bacterial ribosome, which is the cell structure responsible for making proteins. By binding to this subunit, it blocks the enzyme peptidyl transferase, preventing the formation of peptide bonds between amino acids. This stops the bacteria from building essential proteins, which leads to halted growth and eventually bacterial death. It is primarily bacteriostatic, meaning it stops bacteria from multiplying, but it can be bactericidal against certain highly susceptible organisms like Haemophilus influenzae and Streptococcus pneumoniae.
Mechanism Steps
💡 How to Take kemnicol 500 capsule
Strength: Caplet, 500 mg
Dosage Information
| Adult Dosage | The usual adult dose of this medicine is 500 mg taken orally every 6 hours (four times a day) for serious infections. For typhoid fever, the dose may be 500 mg every 6 hours for 14 days. For meningitis, higher doses may be used. The exact dose and duration depend on the type and severity of infection, your weight, kidney and liver function, and other factors. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-medicate. Always follow your doctor's prescription. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. Chloramphenicol is generally avoided in newborns due to the risk of gray baby syndrome. In older children, dosing is weight-based and must be determined by a pediatrician. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of chloramphenicol, especially bone marrow suppression. Dose adjustment may be needed based on liver and kidney function. Regular monitoring is advised. Consult your doctor for appropriate dosing. |
| Renal Impairment | In patients with severe kidney impairment, dose adjustment may be necessary. Chloramphenicol is partially excreted unchanged in urine, so accumulation can occur. Monitor kidney function and adjust dose as needed. Consult your doctor. |
| Hepatic Impairment | In patients with liver impairment, dose reduction may be necessary because chloramphenicol is metabolized in the liver. Monitor liver function tests and adjust dose accordingly. Consult your doctor. |
| Maximum Daily Dose | The maximum recommended daily dose is 4 grams (4000 mg) for adults, but this should not be exceeded. In severe infections, higher doses may be used under strict medical supervision. Always follow your doctor's prescription. |
