Even though syrups are dissolved in different types of solvents such as sugar or Liquor, suspensions are dissolved in h2o.
Suspensions are an easy-to-swallow dosage variety for infants and youngsters who can not swallow reliable dosage forms of medicines.
The primary distinction between a suspension and syrup lies while in the solubility in the components. Inside of a suspension, the good particles will not be soluble while in the liquid medium and thus keep on being dispersed, frequently needing shaking right before use to guarantee uniformity.
