Practical Pharmacological Aspects of Drugs Used for the Treatment of Drug-Resistant Tuberculosis in Adults and Children

ABSTRACT The emergence of resistant strains of Mycobacterium tuberculosis to multiple drugs and the difficulties of their diagnosis and treatment constitute a challenge to global public health. To face this challenge, new anti-tuberculosis drugs, such as bedaquiline, pretomanid, and delamanid, as well as replacement drugs, such as fluoroquinolones, linezolid and clofazimine, are used. Based on the evidence provided by multicenter studies, drugs associated with a better prognosis of drug-resistant tuberculosis have been discovered and, recently, a new classification has been proposed, as well as new totally oral regimens. In this review, we describe current treatment regimens and practical pharmacological aspects required when prescribing new drug-resistant tuberculosis treatment regimens.
