Background:

• Cancer is a leading global cause of death, driving the need for improved chemotherapy.
• Conventional therapies face limitations including toxicity and multidrug resistance.
• Ratiometric codelivery offers a strategy to enhance chemotherapy effectiveness.

Purpose of the Study:

• To review the scientific rationale and importance of ratiometric codelivery in cancer treatment.
• To highlight nanocarrier platforms enabling optimized drug ratios.
• To examine the efficacy and challenges of ratiometric codelivery systems.

Main Methods:

• Review of scientific literature on ratiometric codelivery strategies.
• Focus on nanocarrier systems (liposomes, nanoparticles, dendrimers).
• Analysis of synergistic effects, release kinetics, and therapeutic efficacy.

Main Results:

• Nanocarrier platforms facilitate simultaneous drug delivery in synergistic ratios.
• Ratiometric codelivery demonstrates enhanced efficacy and reduced toxicity in vitro and in vivo.
• Various cancer types show improved outcomes with this approach.

Conclusions:

• Ratiometric codelivery, particularly with nanocarriers, is a promising strategy for advanced cancer chemotherapy.
• Addressing technical challenges and promoting translational research are crucial for clinical application.
• Future research should focus on optimizing ratios and clinical translation for patient benefit.
