Thioacetazone (INN, BAN), also known as amithiozone (USAN), is an oral antibiotic which is used in the treatment of tuberculosis. [1] [2] [3] [4] It has fallen into almost complete disuse due to toxicity and the introduction of improved anti-tuberculosis drugs like isoniazid. [5] The drug has only weak activity against Mycobacterium tuberculosis and is only useful in preventing resistance to more powerful drugs such as isoniazid and rifampicin. It is never used on its own to treat tuberculosis; it is used in a similar way to ethambutol.
There is no advantage to using thioacetazone if the regimen used already contains ethambutol, but many countries in sub-Saharan Africa still use thioacetazone because it is extremely cheap. Use of thioacetazone is declining because it can cause severe (sometimes fatal) skin reactions in HIV positive patients. [6] [7]
The biological target of thioacetazone has proven elusive and its mechanism of action remains unknown, although it is thought to interfere with mycolic acid synthesis. [4]
One of the documented adverse effects of thioacetazone is the excessive accumulation of serum (or blood plasma) in the brain. Another is weakening of the thyroid glands. These were found in a treatment combining conteben with PAS acid p-amino-salicylic acid. [8]
Salicylic acid is an organic compound with the formula HOC6H4COOH. A colorless (or, white), bitter-tasting solid, it is a precursor to and a metabolite of aspirin (acetylsalicylic acid). It is a plant hormone, and has been listed by the EPA Toxic Substances Control Act (TSCA) Chemical Substance Inventory as an experimental teratogen. The name is from Latin salix for willow tree, from which it was initially identified and derived. It is an ingredient in some anti-acne products. Salts and esters of salicylic acid are known as salicylates.
Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. Infection of other organs can cause a wide range of symptoms.
Isoniazid, also known as isonicotinic acid hydrazide (INH), is an antibiotic used for the treatment of tuberculosis. For active tuberculosis, it is often used together with rifampicin, pyrazinamide, and either streptomycin or ethambutol. For latent tuberculosis, it is often used alone. It may also be used for atypical types of mycobacteria, such as M. avium, M. kansasii, and M. xenopi. It is usually taken by mouth, but may be used by injection into muscle.
The rifamycins are a group of antibiotics that are synthesized either naturally by the bacterium Amycolatopsis rifamycinica or artificially. They are a subclass of the larger family of ansamycins. Rifamycins are particularly effective against mycobacteria, and are therefore used to treat tuberculosis, leprosy, and mycobacterium avium complex (MAC) infections.
Rifampicin, also known as rifampin, is an ansamycin antibiotic used to treat several types of bacterial infections, including tuberculosis (TB), Mycobacterium avium complex, leprosy, and Legionnaires' disease. It is almost always used together with other antibiotics with two notable exceptions: when given as a "preferred treatment that is strongly recommended" for latent TB infection; and when used as post-exposure prophylaxis to prevent Haemophilus influenzae type b and meningococcal disease in people who have been exposed to those bacteria. Before treating a person for a long period of time, measurements of liver enzymes and blood counts are recommended. Rifampicin may be given either by mouth or intravenously.
Tuberculosis management describes the techniques and procedures utilized for treating tuberculosis (TB) or simply a treatment plan for TB.
Denis Anthony Mitchison was a British bacteriologist.
Pyrazinamide is a medication used to treat tuberculosis. For active tuberculosis, it is often used with rifampicin, isoniazid, and either streptomycin or ethambutol. It is not generally recommended for the treatment of latent tuberculosis. It is taken by mouth.
4-Aminosalicylic acid, also known as para-aminosalicylic acid (PAS) and sold under the brand name Paser among others, is an antibiotic primarily used to treat tuberculosis. Specifically it is used to treat active drug resistant tuberculosis together with other antituberculosis medications. It has also been used as a second line agent to sulfasalazine in people with inflammatory bowel disease such as ulcerative colitis and Crohn's disease. It is typically taken by mouth.
Iproniazid is a non-selective, irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class. It is a xenobiotic that was originally designed to treat tuberculosis, but was later most prominently used as an antidepressant drug. However, it was withdrawn from the market because of its hepatotoxicity. The medical use of iproniazid was discontinued in most of the world in the 1960s, but remained in use in France until its discontinuation in 2015.
Mycobacterium avium-intracellulare infection (MAI) is an atypical mycobacterial infection, i.e. one with nontuberculous mycobacteria or NTM, caused by Mycobacterium avium complex (MAC), which is made of two Mycobacterium species, M. avium and M. intracellulare. This infection causes respiratory illness in birds, pigs, and humans, especially in immunocompromised people. In the later stages of AIDS, it can be very severe. It usually first presents as a persistent cough. It is typically treated with a series of three antibiotics for a period of at least six months.
Rifapentine, sold under the brand name Priftin, is an antibiotic used in the treatment of tuberculosis. In active tuberculosis it is used together with other antituberculosis medications. In latent tuberculosis it is typically used with isoniazid. It is taken by mouth.
Tuberculous meningitis, also known as TB meningitis or tubercular meningitis, is a specific type of bacterial meningitis caused by the Mycobacterium tuberculosis infection of the meninges—the system of membranes which envelop the central nervous system.
Ethionamide is an antibiotic used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, to treat active multidrug-resistant tuberculosis. It is no longer recommended for leprosy. It is taken by mouth.
Multidrug-resistant tuberculosis (MDR-TB) is a form of tuberculosis (TB) infection caused by bacteria that are resistant to treatment with at least two of the most powerful first-line anti-TB medications (drugs): isoniazid and rifampicin. Some forms of TB are also resistant to second-line medications, and are called extensively drug-resistant TB (XDR-TB).
SQ109 is a drug undergoing development for treatment of tuberculosis.
Tuberculosis in India is a major health problem, causing about 220,000 deaths every year. In 2020, the Indian government made statements to eliminate tuberculosis from the country by 2025 through its National TB Elimination Program. Interventions in this program include major investment in health care, providing supplemental nutrition credit through the Nikshay Poshan Yojana, organizing a national epidemiological survey for tuberculosis, and organizing a national campaign to tie together the Indian government and private health infrastructure for the goal of eliminating the disease.
Delamanid, sold under the brand name Deltyba, is a medication used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, for active multidrug-resistant tuberculosis. It is taken by mouth.
Methaniazide/thioacetazone, sold under the brand name Neothetazone, is an antibiotic combination of methaniazide (neotizide) and thioacetazone that is or was very commonly used in the treatment of tuberculosis. It has been implicated as a cause of gigantomastia in a single 1970 case report, and, along with D-penicilliamine, bucillamine, ciclosporin, and indinavir, is one of the only drugs to have been associated with gigantomastia.
Methaniazide, brand name Neotizide among others, is an antibiotic which was used in the treatment of tuberculosis. It is a derivative of methanesulfonic acid and isoniazid, which is also an antituberculosis drug but has comparatively been far more widely known and used. Isoniazid is a prodrug of isonicotinic acid, and acetylisoniazid, a metabolite of isoniazid, is a metabolic intermediate through which most of the isonicotinic acid is formed. Methaniazide features its mesylate group at the same position as that of the acetyl group in acetylisoniazid, and so methaniazide probably acts as a prodrug of isonicotinic acid similarly to isoniazid and acetylisoniazid. Methaniazide is used as the sodium salt. It was never approved for use or sale in the United States.
Im November 1947 macht der für alles Neue aufgeschlossene Freiburger Internist Professor Dr. Ludwig Heilmeyer, ein Mitschüler des Atomphysikers Heisenberg, die erste schwache Andeutung, daß sich Domagks Präparat in seiner Klinik zu bewähren scheine. Genaue Zahlen gibt aber erst drei Monate später ein bis dahin unbekannter Arzt, Dr. Berthold Mikat, der nur in Vertretung seines Chefs, Dr. Fritz Kuhlmann aus Mölln, spricht: Im Krankenhaus der Landesversicherungsanstalt Schleswig-Holstein ist nach Tb I-Behandlung bei 49 von 66 Patienten mit Lungentuberkulose eindeutige Besserung nachgewiesen worden. Das ist der Start für die Einführung des Tb I, das später den Namen Conteben bekommt.
