Mechanism of action — The antimicrobial activity of INH is selective for mycobacteria, likely due to its ability to inhibit mycolic acid synthesis, which interferes with cell wall synthesis, thereby producing a bactericidal effect
The mechanism of action for PZA is unknown. The parent compound enters the bacterium passively and is metabolized via pyrazinamidase (PZase) within the cytoplasm to pyrazinoic acid; pyrazinoic acid is the active form of the drug
Mechanism of action — Rifampin is thought to inhibit bacterial DNA-dependent RNA polymerase, which appears to occur as a result of drug binding in the polymerase subunit deep within the DNA/RNA channel, facilitating direct blocking of the elongating RNA. This effect is thought to be concentration related
Isonicotinyl hydrazine or isoniazid (INH) has been the mainstay of TB treatment and prevention in both adults and children. When given orally in the fasted state, INH is rapidly absorbed with the maximum concentration (Cmax) occurring 1–2 hours post-dose. Food delays and decreases the extent of absorption.
Pyrazinamide is used in the treatment of tuberculosis (TB) because its sterilizing effect against tubercle bacilli allows the shortening of treatment. It is part of standard treatment for drug-susceptible and drug-resistant TB, and it is being considered as a companion drug in novel regimens
Approximately 80% of rifampicin is transported in blood bound to plasma proteins, mainly albumin. Rifampicin is well distributed, although to a different degree, in the various tissues of the human body. Probably in the hepatocyte, rifampicin undergoes a process of desacetylation.

Isoniazid is an antibiotic used in the treatment of mycobacterium tuberculosis infections. This activity describes the indications, action, and contraindications for isoniazid as a valuable agent in treating both active and latent tuberculosis infection
This medication is an anti-tuberculosis agent, prescribed for tuberculosis(TB). It works by killing or preventing the growth of certain bacteria that cause tuberculosis.
Tuberculosis: Rifampicin, used in combination with other active anti-tuberculosis drugs, is indicated in the treatment of all forms of tuberculosis, including fresh, advanced, chronic and drug-resistant cases. Rifampicin is also effective against most atypical strains of mycobacteria
Isoniazid may interact with foods containing tyramine/histamine (such as cheese, red wine, certain types of fish). This interaction may cause increased blood pressure, flushing of the skin, headache, dizziness, or fast/pounding heartbeat. Tell your doctor right away if any of these symptoms occur
Abacavir Pyrazinamide may decrease the excretion rate of Abacavir which could result in a higher serum level.
Aceclofenac Aceclofenac may decrease the excretion rate of Pyrazinamide which could result in a higher serum level.
Studies and case reports have demonstrated that rifampin accelerates the metabolism of several drugs, including oral anticoagulants, oral contraceptives, glucocorticoids, digitoxin, quinidine, methadone, hypoglycemics, and barbiturates
