Drug targets, current and future therapeutics for the treatment of multi drug resistant tuberculosis with their clinical applications: A critical review

Multi drug-resistant or extensive drug resistance Mycobacterium tuberculosis poses numerous challenges for health care workers and for public health authorities. Treating multidrug resistant or extensive drug resistance tuberculosis continues to be a difficult task, as a longer regimen is associated with a higher number of adverse drug events and economic burden and has a significant negative effect on health care resources. Many trials and observational studies were conducted. Few studies are underway to develop the universal regimen and improve the outcomes related to multi or extensive drug resistance tuberculosis with a shorter regimen duration. The current review will discuss which drug inhibits what target, their synthesis, genetic aspects, repurposed drugs, novel drugs, and extensive trials for the treatment of multi or extensive drug resistance tuberculosis.
