ABSTRACT
Congenital pre-extensively drug-resistant tuberculosis is rare, and administration of second-line anti-tuberculosis medications to neonates is challenging due to the small doses required and limited availability of suitable formulations. Paediatric formulations have increasingly become available but may not be readily accessible in all countries. For the extremely preterm and low birth weight neonate, doses equivalent to a fraction of a tablet or capsule are required, with frequent dose adjustment for increasing age and weight during the course of treatment. The pharmaceutical formulation must be suitable for administration via enteral feeding tube and must be free of unsafe excipients. We report on the challenges, considerations and outcome of an extremely premature neonate with congenital pre-extensively drug-resistant tuberculosis who was successfully treated with second-line anti-tuberculosis medications. Child-friendly formulations were procured where available, and extemporaneous compounding of clofazimine, moxifloxacin and prothionamide oral suspensions was undertaken to enable administration of these medications.
