ABSTRACT
Objectives: The current research work has potential for delivery of fluvoxamine moiety in bio-nanosuspension mode for the effective treatment of depression. Depression is a mood disorder characterized by persistently low mood and a feeling of sadness and loss of interest. Methods: The fluvoxamine loaded bio-nanosuspension was prepared using novel bio-retardant isolated from fruit pulp of Cucumis sativa by a novel method with different ratios (1:1, 1:2, 1:3, 1:4, 1:5) and the same ratios with standard polymer eudragit L-100. The bio-nanosuspensions were evaluated for pH stability studies, percentage entrapment efficacy, in vitro drug release, particle size, polydispersity index, zeta potential, and stability studies. Results: The bio-nanosuspension was subjected to the best formulation based on comparison of above mentioned evaluation parameters, and the Fc1 (1:1) formulation was found to be the best formulation. Cucumis sativa provided excellent stability for the formulation, and the resulting particle size was found to be 194 nm. The bio-nanosuspension had a Polydispersity Index (PDI) of 0.13 with zeta potential of -17.9 mV. Conclusion: The fluvoxamine loaded bio-nanosuspension using Cucumis sativa was found to be nontoxic and compatible with drug delivery systems for treatment of depression. This was the first report in which Cucumis sativa as a bioretardant demonstrated greater retardability over the standard polymer eudragit-100.
