Synthesis and evaluation of isometamidium-alginate nanoparticles on equine mononuclear and red blood cells.

The study presents the development of a nanoparticle-based formulation combining isometamidium hydrochloride and polymers to improve efficacy in treating trypanosomosis, a parasitic disease, while minimizing associated toxicity.

Objective of the Research

• The main aim of the research study was to develop a more effective and less toxic form of drug delivery for isometamidium hydrochloride (ISMM), a medication widely used to treat trypanosomosis. This aimed to enhance the drug’s effectiveness at lower doses and reduce undesirable side effects.

Research Methodology

• The researchers utilized sodium alginate/gum acacia polymers in conjunction with ISMM to create a nanoformulation. The use of these polymers is instrumental in creating nanoparticles capable of delivering the drug effectively.
• The nanoparticle synthesis was characterized using transmission electron microscopy and infrared spectroscopy. These instruments enabled the researchers to evaluate its size, morphology, and functional groups.
• In vitro cytotoxicity of the nanoformulation was assessed using a resazurin assay, a method that determines cell viability by measuring the reduction of the dye resazurin to resorufin.
• The cytotoxicity tests were performed using equine (horse) peripheral blood mononuclear cells at various concentrations of the ISMM-loaded nanoparticles.

Findings of the Research

• The hemolytic assay test, which measures the destruction of red blood cells, revealed that the nanoparticle formulation caused significantly less toxicity compared to the conventional drug. This suggests that the side effects of the conventional drug could be minimized with this new formulation.

Implication of the Study

• This research suggests a significant breakthrough in the treatment of trypanosomosis. If this newly-developed drug delivery method exhibits less toxicity while maintaining or enhancing efficacy as suggested, it could dramatically improve the treatment process.
• While promising, these findings are currently limited to in vitro studies. Further research is needed to evaluate the potency of this drug delivery module in suitable animal models, and ultimately in humans.
