Methods of Syrup Preparation
Agitation with Heat
Agitation w/o heat
Reconstitution
Percolation
Rapid method syrup preparation for nonvolatile and non-heat labile drugs
Agitation with Heat
80-85C
Occurrence of Sugar Inversion
Sucrose -> Glucose, Fructose
Agitation with heat
Slow process, prevents sucrose inversion
Agitation without heat
Addition of sugar to a medicated liquid; used w/ fluidextratcs and tinctures
Reconstitution
Purified water is passed slowly through a bed of crystalline of sucrose, dissolving it and forming syrup
Reconstitution
Thick liquid preparations somewhat allied to the syrups
Honey
Honey is used as Base
Treatment of certain types of ulcers and abscess
Honeys
Thick, viscid, adhesive liquids produced by dispensing gum in water.
Mucilages
Use of Mucilages
Suspending Agent
Acacua mucilage
35% dispersion in water
Preservative: Benzoic Acid
Tragacanth Mucilage
6% dispersion in water
