An Overview on Nanosuspension Technology

Abstract

Nanosuspension is a colloidal dispersion of submicron-sized particles (typically in the nanometer range) of an active pharmaceutical ingredient (API) in a liquid medium, often water or a water-miscible solvent. This review article provides an in-depth overview of nanosuspensions, a promising drug delivery system with its various advantages. We have discussed various techniques employed for preparing nanosuspensions. In this review article different types of evaluation parameters are discussed like organoleptic properties, particle size distribution, zeta potential, crystal morphology, dissolution velocity and saturation solubility, pH, droplet size, drug content along with viscosity measurement which can be used for the evaluation of nanosuspension.
