Purpose of review

Nowadays tuberculosis is becoming a worldwide problem, and according to the World Health Organization, which declared tuberculosis a global health emergency in 1993, each year 8 million people worldwide develop the active disease and almost 3 million die.

Recent findings

Due to this problem there is an urgent need for new strategies and drugs to fight against this disease. In this context, this review describes promising new classes of compounds against tuberculosis that are under study, as well as promising drugs that may soon be introduced onto the market. Another subject reported in this review is inhaled therapy, an important route under study for delivering antitubercular drugs directly to the lungs.


The implications of new drugs and inhaled therapy in tuberculosis treatment are fewer toxic side-effects, improved pharmacokinetics properties, extensive and potent activity against Gram-positive and Gram-negative bacteria, including resistant strains, and a reduction in the total treatment time.
