Isoniazid-Loaded Albumin Nanoparticles: Taguchi Optimization Method

Area of Science:

• Biomaterials Science
• Pharmaceutical Nanotechnology
• Infectious Disease Research

Background:

• Tuberculosis (TB) remains a major global health threat, necessitating novel drug delivery systems for resistant strains.
• Biocompatible polymer nanoparticles, such as bovine serum albumin (BSA), show promise as carriers for anti-TB drugs.
• Optimizing nanoparticle characteristics is crucial for effective drug transport and therapeutic outcomes.

Purpose of the Study:

• To investigate the impact of reactant concentrations on the characteristics of bovine serum albumin-isoniazid (BSA-INH) nanoparticles.
• To identify optimal concentrations of BSA, isoniazid, urea, and cysteine for nanoparticle formulation.
• To enhance the potential of BSA-INH nanoparticles for treating drug-resistant tuberculosis.

Main Methods:

• BSA-INH nanoparticles were synthesized using ethanol desolvation.
• Natural stabilizers, urea and cysteine, were employed post-desolvation.
• The Taguchi method was applied to systematically analyze the effect of four component concentrations (BSA, isoniazid, urea, cysteine) on nanoparticle parameters.

Main Results:

• Nanoparticle characteristics, including diameter, polydispersity, drug loading, and yield, were significantly influenced by the concentrations of BSA, isoniazid, urea, and cysteine.
• The Taguchi analysis identified specific concentration ranges for each component that optimize BSA-INH nanoparticle properties.
• This systematic approach provides a framework for reproducible and efficient nanoparticle production.

Conclusions:

• The concentration of reacting components critically affects BSA-INH nanoparticle characteristics for TB treatment.
• The Taguchi method is effective in optimizing nanoparticle formulation parameters.
• This research contributes to the development of advanced drug delivery systems for combating drug-resistant tuberculosis.
