Aim: To investigate eutectic liquid-based emulsion-like dispersions for intratympanic injections to augment cinnarizine permeability across round window membrane in a healthy rabbit inner ear model. Methods: Two-tier systematic optimization was used to get the injection formula. The drug concentrations in perilymph and plasma were analyzed via. Ultra-performance liquid chromatography-tandem mass spectrometry method after 30-, 60-, 90- and 120-min post intratympanic injection time points in rabbits. Results: A shear-thinning behavior, immediate drug release (∼98.80%, 10min) and higher cell viability (>97.86%, 24h) were observed in dispersions. The cinnarizine level of 8168.57±1236.79ng/ml was observed in perilymph at 30min post intratympanic injection in rabbits. Conclusion: The emulsion-like dispersions can augment drug permeability through round window membrane.
