Pasiniazid is a composition of isoniazid and 4-aminosalicylic acid, that has mutual effects coupling isoniazid and 4-aminosalicylic acid for use in tuberculosis patients. Isoniazid is a bactericidal agent active against organisms of the genus Mycobacterium, specifically M. tuberculosis, M. bovis and M. kansasii. Isoniazid is a prodrug and must be activated by bacterial catalase. Isoniazid inhibits InhA, the enoyl reductase from Mycobacterium tuberculosis, by forming a covalent adduct with the NAD cofactor. 4-Aminosalicylic acid is an anti-tuberculosis drug used to treat tuberculosis in combination with other active agents. There are two mechanisms responsible for aminosalicylic acid's bacteriostatic action against Mycobacterium tuberculosis. Firstly, aminosalicylic acid inhibits folic acid synthesis (without potentiation with antifolic compounds). The binding of para-aminobenzoic acid to pteridine synthetase acts as the first step in the folic acid synthesis. Aminosalicylic acid binds pteridine synthetase with greater affinity than para-aminobenzoic acid, effectively inhibiting the synthesis of folic acid. As bacteria are unable to use external sources of folic acid, cell growth and multiplication slow. Secondly, the aminosalicylic acid may inhibit the synthesis of the cell wall component, mycobactin, thus reducing iron uptake by M. tuberculosis.

Conditions:

Isoniazid pyruvate is a metabolite of isoniazid. Isoniazid (Laniazid, Nydrazid), also known as isonicotinylhydrazine (INH), is an organic compound that is the first-line medication in prevention and treatment of tuberculosis. It has been claimed that isoniazone pyruvate causes less excretion of pyridoxine than isoniazid and might therefore be less likely to cause peripheral neuritis.

Capreomycin is an antibiotic, which is used in combination other antituberculosis drugs fro the treatment of pulmonary infections caused by capreomycin-susceptible strains of M. tuberculosis when the primary agents (isoniazid, rifampin, ethambutol, aminosalicylic acid, and streptomycin) have been ineffective or cannot be used because of toxicity or the presence of resistant tubercle bacilli. Little is known about capreomycin's exact mechanism of action, but it is thought to inhibit protein synthesis by binding to the 70S ribosomal unit. Capreomycin also binds to components in the bacterial cell which result in the production of abnormal proteins.

Ethionamide is a second-line agent, structurally similar to isoniazid, used as a second-line therapy for the treatment of multidrug-resistant tuberculosis or active tuberculosis in case of patient intolerance to other drugs. Depending on its the concentration at the infected site and the susceptibility of the infecting organism it may be bacteriostatic or bactericidal. When used alone rapidly develops bacterial resistance. Ethionamide was approved by FDA in 1965 as TRECATOR manufactured by Wyeth Pharmaceuticals Inc. (purchased by Pfizer in 2009). Ethionamide is specific for Mycobacteria and is thought to exert a toxic effect on mycolic acid components of the bacterial cell wall when activated through intermediate S-oxidation by EtaA. Mycolic acid synthesis was shown to be inhibited by ethionamide in the EthA protein-overexpressing mycobacteria,

Methaniazide (metaniazide) is the methanesulfonate derivative of isoniazid with antibacterial properties. It is used used primarily as a tuberculostatic. It remains the treatment of choice for tuberculosis.

Isoniazid glucuronate is a less toxic derivative the antibacterial drug isoniazid. Isoniazid is recommended for all forms of tuberculosis in which organisms are susceptible. Isoniazid itself is a prodrug and must be activated by bacterial catalase. Isoniazid inhibits InhA, the enoyl reductase from Mycobacterium tuberculosis, by forming a covalent adduct with the NAD cofactor.
