Q
ADVANTAGES OF POWDERS
A
- Flexibility of compounding
- Good chemical stability
- Rapid dispersion of ingredients because of the small particle size
3
Q
DISADVANTAGES
A
- Time-consuming preparation
- Inaccuracy of dose
- Unsuitability for many unpleasant-tasting, hygroscopic, and deliquescent drugs

Q
- Triturating it in a mortar and pestle or using an ointment slab and spatula.
- This method is often used to prevent a gritty feel when solids are incorporated into dermatologic or ophthalmic ointments and suspensions.
- Products: paste

Q
- using an additional materials in which that material is soluble - a volatile solvent that evaporates
- The dissolved powder is then mixed in a mortar or spread on an ointment slab to enhance the evaporation of the solvent. As the solvent evaporates, the powder will recrystallize out of solution as fine particles
- This technique is often used with gummy substances that reagglomerate or resist grinding
- By grinder & mill
A
PULVERIZATION BY INTERVENTION
14
Q
Example of volatile solvent
A
ALCOHOL
ACETONE
15
Q
- A spatula is used to blend small amounts of powders on a sheet of paper or a pill tile.
- This method is not suitable for large quantities of powders or for powders that contain potent substances because homogeneous blending may not occur.
- This method is particularly useful for solid substances that liquefy or form eutectic mixtures (i.e., mixtures that melt at a lower temperature than any of their ingredients) when in close, prolonged contact with one another because little compression or compaction results.
A
SPATULATION
16
Q
These substances include phenol, camphor, menthol, thymol, aspirin, phenylsalicylate, and phenacetin.
A
EUTECTIC MIXTURES
17
Q
To diminish contact, powders prepared from eutrectic mixtures are commonly mixed with an
A
INERT DILUENT
18
Q
prevents eutexia with aspirin, phenylsalicylate, and other troublesome compounds
A
SILICIC ACID (20%)
19
Q
- If comminution is desired, a porcelain or ceramic mortar with a rough inner surface is preferred to a glass mortar with a smooth working surface.
- A glass mortar is preferable for chemicals that stain a porcelain or ceramic surface as well as for simple admixture of substances without special need for comminution. A glass mortar cleans more readily after use.
A
TRITURATION
20
Q
- is used when potent substances must be mixed with a large amount of diluent.
- The potent drug and an approximately equal volume of diluent are placed in a mortar and thoroughly mixed by trituration.
- A second portion of diluent, equal in volume to the powder mixture in the mortar, is added, and trituration is repeated. The process is continued; equal volumes of diluent are added to the powder mixture in the mortar until all of the diluent is incorporated.
A
GEOMETRIC DILUTION
21
Q
- Powders are mixed by passing them through sifters similar to those used to sift flour.
- This process results in a light, fluffy product. Usually, it is not acceptable for incorporating potent drugs into a diluent base.
A
SIFTING
22
Q
- is the process of mixing powders in a large container rotated by a motorized process.
- These blenders are widely used in industry, as are large-volume powder mixers that use motorized blades to blend the powder in a large mixing vessel.
