What is Delamanid used for?
Delamanid is an antibiotic used to treat multidrug resistant tuberculosis. Delamanid is an anti-tuberculosis agent derived from the nitro-dihydro-imidazooxazole class of compounds that inhibits mycolic acid synthesis of bacterial cell wall 1.
What is the definition of a multidrug resistant Mycobacterium tuberculosis?
Multidrug-resistant TB (MDR TB) is caused by an organism that is resistant to at least isoniazid and rifampin, the two most potent TB drugs. These drugs are used to treat all persons with TB disease.
Is Delamanid FDA approved?
Unlike the two other new drugs in the TB arsenal, bedaquiline and delamanid, pretomanid is the first FDA-approved TB drug to be developed and registered by a non-profit organisation, the TB Alliance.
How do you test for multidrug resistant TB?
It has been reported in 117 countries worldwide. Drug resistance can be detected using special laboratory tests which test the bacteria for sensitivity to the drugs or detect resistance patterns. These tests can be molecular in type (such as Xpert MTB/RIF) or else culture-based.
What is the mechanism of action of Delamanid?
MECHANISM OF ACTION Delamanid is a dihydro-nitroimidazooxazole derivative. It acts by inhibiting the synthesis of mycobacterial cell wall components, methoxy mycolic acid and ketomycolic acid. Delamanid is a pro-drug which gets activated by the enzyme deazaflavin dependent nitroreductase (Rv3547).
What is the side effects of Delamanid?
Side effects
| MedDRA Preferred Term | Side effect | Labels |
|---|---|---|
| Nausea | Nausea | x |
| Vomiting | Vomiting | x |
| Dizziness | Dizziness | x |

How is multidrug resistant TB treated?
MDR regimens should include at least pyrazinamide, a fluoroquinolone, an injectable anti-TB drug, ethionamide (or prothionamide) and either cycloserine or PAS (para-aminosalycylic acid) if cycloserine cannot be used (conditional recommendation, very low quality evidence)(1).
What is the difference between MDR and XDR-TB?
Multidrug resistant tuberculosis (MDR-TB) is a strain of TB that cannot be treated with the two most powerful first-line treatment anti-TB drugs. Extensively drug resistant tuberculosis (XDR-TB) is a form of TB caused by bacteria that are resistant to several of the most effective anti-TB drugs.
When was Delamanid approved by FDA?
Delamanid was conditionally approved by FDA for the treatment of MDR-TB in 2014 based on phase II data (Ryan and Lo 2014) . Very recently, pretomanid was approved for the treatment of a small group of adult patients with severe XDR-TB (Keam 2019). …

What is Genexpert test for TB?
Introduction: Gene-Xpert, a CBNAAT (catridge based nucleic acid amplification test) is a widely accepted diagnostic test for Tuberculosis. This test is a rapid diagnostic test for Tuberculosis detection as well as Rifampicin resistance in direct smear negative cases.
How do you take bedaquiline?
Bedaquiline comes as a tablet to take by mouth with water. It is usually taken with food once a day for 2 weeks and then three times a week for 22 weeks. When you are taking bedaquiline three times a week, allow at least 48 hours between doses.
How is Delamanid used in the treatment of tuberculosis?
Delamanid was associated with an increase in sputum-culture conversion at 2 months among patients with multidrug-resistant tuberculosis. This finding suggests that delamanid could enhance treatment options for multidrug-resistant tuberculosis.
Which is the best drug to treat MDR-TB?
Bedaquiline and delamanid are the most promising novel drugs for the treatment of MDR-TB, each having a high efficacy and tolerability. However, the best regimen for achieving better outcomes and reducing adverse drug reactions remains yet to be determined, with safety concerns regarding cardiac events due to QT prolongation still to be addressed.
How is Delamanid related to sputum culture conversion?
Although no clinical events due to QT prolongation on electrocardiography were observed, QT prolongation was reported significantly more frequently in the groups that received delamanid. Delamanid was associated with an increase in sputum-culture conversion at 2 months among patients with multidrug-resistant tuberculosis.
What kind of tuberculosis is resistant to rifampin?
The emergence over the past two decades of multidrug-resistant tuberculosis, or tuberculosis caused by strains of Mycobacterium tuberculosis that are resistant to isoniazid and rifampin, with or without resistance to other agents, has greatly complicated efforts to control the global tuberculosis epidemic.
