ISONIAZID vs LAMPRENE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits mycolic acid synthesis in Mycobacterium tuberculosis via activation by catalase-peroxidase (KatG) to form reactive species that target InhA, a NADH-dependent enoyl-acyl carrier protein reductase.
Clofazimine binds preferentially to mycobacterial DNA, inhibiting replication and exerting antimicrobial activity. It also has anti-inflammatory properties by modulating immune responses.
5 mg/kg orally once daily (max 300 mg/day) or 15 mg/kg orally twice weekly (max 900 mg/dose)
300 mg orally once daily in combination with other antimycobacterial agents.

1-4 hours (fast acetylators), 2-5 hours (slow acetylators); prolonged in hepatic impairment.
Clinical Note
moderateIsoniazid + Artesunate
"The serum concentration of the active metabolites of Artesunate can be reduced when Artesunate is used in combination with Isoniazid resulting in a loss in efficacy."
Clinical Note
moderateIsoniazid + Clotrimazole
"The metabolism of Clotrimazole can be decreased when combined with Isoniazid."
Clinical Note
moderateIsoniazid + Ketoconazole
"The serum concentration of Ketoconazole can be decreased when it is combined with Isoniazid."
Clinical Note
moderateTerminal elimination half-life ranges from 8 to 70 days (mean approximately 14 days) due to extensive tissue storage and slow release; may be longer with chronic dosing.
Renal (75-95% as metabolites and parent drug), fecal (<10%), biliary (minor).
Primarily fecal (unabsorbed drug and biliary excretion); renal excretion accounts for <1% of the dose as unchanged drug and metabolites.
