New drugs and perspectives for new anti-tuberculosis regimens.

Tuberculosis (TB) is the ninth cause of global death, more than any other infectious disease. With growing drug resistance the epidemic remains and will require significant attention and investment for the elimination of this disease to occur. With susceptible TB treatment not changing over the last four decades and the advent of drug resistance, new drugs and regimens are required. Recently, through greater collaboration and research networks some progress with significant advances has taken place, not withstanding the comparatively low amount of resources invested. Of late the availability of the new drugs bedaquiline, delamanid and repurposed drugs linezolid, clofazimine and carbapenems are being used more frequently in drug-resistant TB regimens. The WHO shorter multidrug-resistant tuberculosis regimen promises to reach more patients and treat them more quickly and more cheaply. With this new enthusiasm and hope we this review gives an update on the new drugs and perspectives for the treatment of drug-susceptible and drug-resistant tuberculosis.
