How long does it take to treat TB?
TB disease can be treated by taking several drugs for 6 to 9 months. There are 10 drugs currently approved by the U.S. Food and Drug Administration (FDA) for treating TB. Of the approved drugs, the first-line anti-TB agents that form the core of treatment regimens are: isoniazid (INH) rifampin (RIF)
What is it called when TB bacteria multiply?
When TB bacteria become active (multiplying in the body) and the immune system can’t stop the bacteria from growing, this is called TB disease. TB disease will make a person sick. People with TB disease may spread the bacteria to people with whom they spend many hours.
What is XDR TB?
Extensively drug-resistant TB (XDR TB) is a rare type of MDR TB that is resistant to isoniazid and rifampin, plus any fluoroquinolone and at least one of three injectable second-line drugs (i.e., amikacin, kanamycin, or capreomycin). Treating and curing drug-resistant TB is complicated.
Can TB be treated?
It is very important that people who have TB disease are treated, finish the medicine, and take the drugs exactly as prescribed. If they stop taking the drugs too soon, they can become sick again; if they do not take the drugs correctly, the TB bacteria that are still alive may become resistant to those drugs.
How long has triple therapy been used for tuberculosis?
All together, “triple therapy” remained the standard treatment for all forms of tuberculosis for nearly 15 years ( 21 ). Despite these successes, side effects, drug resistance, and the large numbers of affected people drove further drug development exploration.
What was the first step in finding a cure for tuberculosis?
The first step in finding a cure was the discovery of the cause of tuberculosis by Robert Koch in 1882.
How long does pyrazinamide treatment last?
Incorporation of pyrazinamide into the first-line regimen led to a further reduction of treatment duration to six months. Treatment of multiple drug–resistant tuberculosis remains a difficult problem requiring lengthy treatment with toxic drugs.
Is isoniazid safe for tuberculosis?
In 1952, isoniazid opened the modern era of treatment; it was inexpensive, well tolerated, and safe. In the early 1960s, ethambutol was shown to be effective and better tolerated than para -aminosalicylic acid, which it replaced. In the 1970s, rifampin found its place as a keystone in the therapy of tuberculosis.
When was streptomycin discovered?
The discovery of streptomycin brought about a great flurry of drug discovery research that lasted from the 1940s through the 1960s. As the decline in tuberculosis case rates became steeper, the awareness of the public waned. The war on tuberculosis was considered winnable with the tools at hand ( 43 ).
When did tuberculosis recur?
Decreased attention to tuberculosis control and poor public health infrastructure worldwide led to a resurgence of tuberculosis in the late 1980s and early 1990s. Between 1985 and 1992, tuberculosis cases increased by about 20% in the United States.

Gerhard Domagk's research, which led to the discovery of sulfonamides in the 1930s, eventuated in the discovery of the anti‐TB activity isonicotinic acid hydrazide (INH) in 1952. Adding INH to PAS and SM (“triple therapy”) resulted in predictable cures for 90–95% of patients, the Holy Grail.
How long does it take to cure TB?
Although the usual case of drug-susceptible TB can be predictably cured in 6 months with a reasonably nontoxic, economical regimen involving as few as 62–78 encounters, novel methodologies must be established if TB is going to be controlled in the decades ahead.
