Nanotechnological innovations in paediatric tuberculosis management: current trends and future prospects
Abstract
Paediatric Tuberculosis (TB) continues to be a major global cause of morbidity and mortality. Children are more prone to contracting TB, which can spread quickly to extrapulmonary infection sites. Although the pathophysiology of the disease, drug pharmacokinetics, and the therapeutic window in children differ from those of adults, the same drugs used to treat adult TB have long been utilised to treat paediatric TB infections. Since many current formulations such as tablets are unsuitable for children due to difficulty swallowing and risk of choking, adult medications are frequently used by breaking or crushing tablets to obtain a paediatric dose. This can result in inaccurate dosing due to pharmacokinetic differences in children which could subsequently lead to sub-therapeutic or toxic systemic concentrations. In addition, many of the medications used in the treatment of TB and most medicines in general, have a profoundly unpleasant taste to children causing them to reject and spit out medication which contributes to challenges with adherence, ultimately leading to treatment failure. The aforementioned demonstrates a huge need for the development of novel drug delivery formulations that are paediatric-friendly and address the limitations of current dosage forms. This review discusses the currently available oral paediatric formulations, recent developments of novel oral drug delivery systems studied to overcome the current problems associated with the treatment of tuberculosis in paediatrics and provides potential direction for future research through nanotechnology by using a SWOT analysis.
