Polymeric Nanoparticles: A Holistic Approach to Combat Tuberculosis.

Area of Science:

• Nanomedicine
• Polymer Science
• Infectious Diseases

Background:

• Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) pose significant global health challenges.
• Current anti-tubercular drug (ATD) therapies often involve long treatment durations and high doses, leading to poor patient compliance due to intolerance and toxicity.
• Nanoparticulate drug delivery systems have emerged as a promising strategy for treating various diseases, including TB.

Purpose of the Study:

• To review the application of polymeric nanoparticles (PNPs) for delivering anti-tubercular drugs (ATDs).
• To highlight the advantages of PNPs in enhancing the efficacy of TB treatment and minimizing drug-associated toxicity.
• To emphasize the role of PNPs in addressing the challenges posed by drug-resistant TB.

Main Methods:

• Review of current literature on nanoparticulate drug delivery systems for TB treatment.
• Focus on encapsulation and conjugation of ATDs to polymeric nanoparticles (PNPs).
• Discussion of nanoparticle characteristics relevant to drug delivery, including stability, loading efficiency, and carrying capacity.

Main Results:

• Polymeric nanoparticles (PNPs) offer enhanced stability, high loading efficiency, and high carrying capacity for ATDs.
• PNPs facilitate controlled or sustained drug release, improving drug bioavailability and enabling dose reduction.
• The use of natural and synthetic polymers in PNPs can help mitigate the side effects of chemotherapeutics.

Conclusions:

• Polymeric nanoparticles (PNPs) represent a significant advancement in anti-tubercular drug delivery systems.
• PNPs have the potential to overcome challenges associated with MDR and XDR-TB by improving treatment efficacy and patient compliance.
• Further research and application of PNPs are crucial for combating the global TB epidemic.
