Mycobacterium tuberculosis treatment modalities and recent insights

Area of Science:

• Microbiology
• Pharmacology
• Nanotechnology

Background:

• Antimicrobial therapy for Mycobacterium tuberculosis infections faces challenges due to poor treatment response and recurrence.
• Mycobacterium tuberculosis exhibits intracellular survival and poor antibiotic penetration into host cells, necessitating prolonged treatment durations (6-9 months).

Purpose of the Study:

• To review current strategies and challenges in tuberculosis treatment.
• To explore advancements in intracellular drug delivery using nanoparticles for tuberculosis therapy.

Main Methods:

• Review of existing literature on tuberculosis treatment, antibiotic mechanisms, and drug resistance.
• Analysis of various nano- and micro-formulations for targeted intracellular drug delivery.

Main Results:

• Antibiotics are effective against Mycobacterium tuberculosis in vitro within two weeks.
• Nano- and micro-formulations demonstrate preferential drug delivery into host cells, improving stability and bioavailability compared to free drugs.

Conclusions:

• Nanoparticle-based drug delivery systems show promise for enhancing the efficacy of tuberculosis treatment by targeting intracellular Mycobacterium tuberculosis.
• Further research into nano- and micro-formulations is crucial for overcoming challenges in tuberculosis therapy.
