Answer
Geometric dilution is a pharmaceutical process in which a small amount of a drug is thoroughly mixed with an appropriate amount of a diluent, an inert substance that thins or binds the drug. According to the UNC Eshelman School of Pharmacy, it ensures that the drug is distributed evenly throughout the resulting compound.
It is also important to understand why geometric dilution is important.
To obtain the most accurate measurement of a medication/substance.
When mixing unequal amounts of powders, why is geometric dilution used?
A homogeneous (fully and evenly combined) mixture will NOT result from simply mixing two powders together without using geometric dilution.
Likewise, how do you Triturate?
Method of Trituration A trituration is a weight-based dilution of a potent drug powder with an inert diluent powder, typically lactose. To maintain an acceptable range of accuracy, we can then remove a weighable portion (aliquot) of the mixture containing the desired amount of substance.
Similarly, what exactly is the doubling up technique?
To ensure a final homogeneous mixture, the doubling-up technique is used: To the mortar, add the ingredient with the least amount of bulk. Add the second ingredient in roughly the same amount as the first, doubling the bulk already present in the mortar. 3.
What is the distinction between trituration and levying?
The continuous rubbing or grinding of the powder in a mortar with a pestle is known as trituration. Levigation reduces particle size by triturating it in a mortar or spatulating it on an ointment slab or pad with a small amount of a non-soluble liquid.

What exactly is interventional pulverisation?
The process of rubbing, grinding, or pulverising a substance to produce fine particles is known as trituration. The process of reducing the size of particles in a solid using an additional material that is soluble – a volatile solvent that evaporates – is known as pulverisation by intervention.
How do you make a drug compound?
The art and science of preparing personalised medications for patients is known as pharmacy compounding. Compounded medications are created on the basis of a practitioner’s prescription, in which individual ingredients are combined in the exact strength and dosage form required by the patient.
What type of balance is used in pharmacies for compounding?
Prescription Balance in Class III. Most pharmacists will weigh their patients using a Class III prescription balance. In fact, pharmacies are required by law to maintain such a balance.
What exactly is a compounding log?
Designed for recording compounded prescription entries. The log will help staff identify the specific ingredients used, the supplier, the expiration date, the lot number, and the quantity measured or weighed.
In pharmacy, what is comminution?
Comminution. Comminution is the physical reduction of a substance to fine particle size, which makes it easier to dissolve and compound. Cutting, grating, grinding, pulverising, trituration, and levitation are comminution processes.
What is the purpose of granules?
Small fine or coarse particles are converted into larger agglomerates known as granules during the granulation process. Granules improve the uniformity of the API, increase the density of the blend, make metering or volumetric dispensing easier, reduce dust, and improve product appearance.
What’s the distinction between granules and powder?
Powder and granule differ as nouns in that powder is the fine particles to which any dry substance is reduced by pounding, grinding, or triturating, or into which it falls by decay; dust, whereas granule is a tiny grain, a small particle.
Why are some medications packaged as divided powders?
ARE THERE PHARMACEUTICAL POWDERS? Because the patient is not involved in the dosage measurement, divided powder is a more accurate dosage form than bulk powder. Cellophane and foil-enclosed powders are more protected from the outside environment until administration than paper-enclosed powders.
What exactly is divided powder?
Powders Separated (Chartulae; Charts; Powder Papers) Single doses of powdered medicinals individually wrapped in cellophane, metallic foil, or paper are referred to as divided powders or charts. Because the patient is not involved in the dosage measurement, divided powder is a more accurate dosage form than bulk powder.
What excipients are present in powders?
Gelatin, cellulose, cellulose derivatives, polyvinylpyrrolidone, starch, sucrose, and polyethylene glycol are a few examples. Dry binders are added to the powder blend after wet granulation or as part of a direct powder compression (DC) formula.
What is the procedure for Levigating powder?
Levigation. Levigation is the wet grinding of an insoluble substance to a fine powder. The material is fed into the mill along with water, in which the powdered substance remains suspended, and exits as a turbid liquid or thin paste, depending on the amount of water used.
