Febuxostat, sold under the brand name Uloric among others, is a medication used long-term to treat gout due to high uric acid levels. [7] It is generally recommended only for people who cannot take allopurinol .
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.
A xanthine oxidase inhibitor is any substance that inhibits the activity of xanthine oxidase, an enzyme involved in purine metabolism.In humans, inhibition of xanthine oxidase reduces the production of uric acid, and several medications that inhibit xanthine oxidase are indicated for treatment of hyperuricemia and related medical conditions including gout.

M. tuberculosis develops resistance to drugs by spontaneous mutations in its genomes. These types of mutations can lead to genotype and phenotype changes that can contribute to reproductive success, leading to the evolution of resistant bacteria. Resistance to one drug is common, and this is why treatment is usually done with more than one drug.
An illustrative diagram explaining drug resistance. Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition. [1] The term is used in the context of resistance that pathogens or cancers have "acquired", that is, resistance has evolved.
Extensively drug-resistant tuberculosis (XDR-TB) is a form of tuberculosis caused by bacteria that are resistant to some of the most effective anti-TB drugs. XDR-TB strains have arisen after the mismanagement of individuals with multidrug-resistant TB (MDR-TB).
Drug resistance, such as antimicrobial resistance or antineoplastic resistance, may make the first-line drug ineffective, especially in case of multidrug-resistant pathogens and tumors. Such an alternative may be outside of extant regulatory requirements or medical best practices, in which case it may be viewed as salvage therapy .
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 .
