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. [3]
Rifampin rapidly kills fast-dividing bacilli strains as well as "persisters" cells, which remain biologically inactive for long periods of time that allow them to evade antibiotic activity. [7] In addition, rifabutin and rifapentine have both been used against tuberculosis acquired in HIV-positive patients.
[4] Complementary colors can create some striking optical effects. The shadow of an object appears to contain some of the complementary color of the object. For example, the shadow of a red apple will appear to contain a little blue-green. This effect is often copied by painters who want to create more luminous and realistic shadows.
Rifapentine, sold under the brand name Priftin, is an antibiotic used in the treatment of tuberculosis. [2] In active tuberculosis it is used together with other antituberculosis medications. [2]
When staring at a bright color for a while (e.g. red), then looking away at a white field, an afterimage is perceived, such that the original color will evoke its complementary color (green, in the case of red input). When complementary colors are combined or mixed, they "cancel each other out" and become neutral (white or gray).
The hope of a fixed-dose combination pill is to increase the likelihood that people will take all of three medications. [5] Also, if people forget to take one or two of their drugs, they might not then develop resistance to the remaining drugs.
Scientists at the Italian drug company Achifar discovered rifabutin in 1975. (Eventually Archifar became part of Farmitalia Carlo Erba, a unit of the conglomerate Montedison which was subsequently bought by Pharmacia) This company's Adria Laboratories subsidiary filed for Food and Drug Administration (FDA) approval of rifabutin under the brand name Mycobutin in the early 1990s and the drug ...
Isoniazid/rifampicin, also known as isoniazid/rifampin, is a medication used to treat tuberculosis. [1] It is a fixed dose combination of isoniazid and rifampicin (rifampin). [1] It is used together with other antituberculosis medication. [1] It is taken by mouth. [1] It is on the World Health Organization's List of Essential Medicines. [2]
