🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two antitubercular drugs with distinct mechanisms. Rifampicin inhibits bacterial DNA-dependent RNA polymerase, preventing the synthesis of messenger RNA and thereby stopping protein production in Mycobacterium tuberculosis. Isoniazid is a prodrug activated by bacterial catalase-peroxidase; it then inhibits mycolic acid synthesis, which is essential for the bacterial cell wall. The combination is synergistic and helps prevent the emergence of resistant strains.

Dosage Information
| Adult Dosage | The dosage of this medicine is individualized by a qualified clinician based on the patient's weight, age, renal and hepatic function, and the specific type of tuberculosis. Typically, rifampicin is dosed at 10 mg/kg and isoniazid at 5 mg/kg daily, but this combination tablet provides fixed amounts. It is usually taken once daily on an empty stomach. 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 require dose adjustments due to reduced liver and kidney function. Close monitoring is advised. Dose must be individualized by a qualified clinician. |

| Hepatic Impairment | Use with caution in patients with hepatic impairment. Dose reduction or alternative regimens may be necessary. Regular monitoring of liver function is essential. |
| Maximum Daily Dose | The maximum daily dose should not exceed the recommended therapeutic dose as determined by a clinician. Typically, rifampicin 600 mg and isoniazid 300 mg daily, but this combination provides lower doses per tablet. |
