What is it about?
This work focused on the identification and optimization of formulation and process variables affecting the characteristics of nanosuspension, using the Esomeprazole magnesium as a drug candidate. Formulation factors evaluated were ratio of stabilizers to drug and ratio of anti-solvent to solvent, whereas process parameters were ultrasonication time, power input, stirring speed and process temperature effect. The test revealed that ratio of the stabilizer to drug and ratio of anti-solvent to solvent has the significant effect on zeta potential and particle size, whereas different process parameters have significant effect on the particle size and their distribution.

Why is it important?
Optimization of nanosuspension using the anti solvent precipitation ultrasonication method is a complex process since it includes a large number of factors that affects the nanosuspension characteristics. This study helped in identifying the certain formulation and process parameters
Perspectives
The stability problems related to drug nanosuspensions may be moderately solved by using the stabilizers; however, their screening and selection of stabilizers still a very challenging issue in the pharmaceutical field. The challenge arises mainly from lack of an efficient technique used for screening of suitable stabilizers. At present time, the stabilizer screening processes need the trial production of nanosuspensions using different stabilizers. This practice requires a lot of effort, time and quantity of the different stabilizers. So, this field remains very challenging and offers a lot of research work in the future.
