Viscosity could be crucial from the processing facet to reduce segregation. Additionally, viscosity has also been revealed to get associated with bioequivalency. pH may even have some that means concerning performance of preservative techniques and should even have an impact on the amount of drug in Resolution.
The manufacture and control of oral alternatives and oral suspensions has presented some problems on the sector.
