Suspension is a liquid dosage kind which contains Active pharmaceutical components (APIs) blended with a small amount of stable particles. The stable particles are insoluble in liquid, so some elements of them stay suspended from the liquid.
This doc delivers specifics of syrups, such as their definition, types, elements, preparing solutions, and packaging. A syrup is outlined as being a concentrated aqueous preparing of sugar or sugar substitute, which can comprise flavorings or medicinal substances.
