1/1 Da Powder And Granules

The given answer is true. When making powders, there is a manufacturing expense because each powder dose needs to be individually wrapped. This process of individually wrapping the powder doses adds to the overall manufacturing cost.

Powders have several advantages, including no difficulty swallowing, easy adjustment of dose, and rapid onset of action. Powders can be easily dissolved in liquid, making them easier to swallow for individuals who have difficulty swallowing tablets or capsules. Additionally, powders allow for easy adjustment of dose as they can be measured and divided more accurately. Lastly, powders often have a faster onset of action compared to other forms of medication, as they are quickly absorbed by the body. Therefore, all of the options listed above are advantages of powders.

The term "Moderatly Fine" is not a USP term for powders. The USP (United States Pharmacopeia) defines specific terms and standards for powders used in pharmaceuticals. "Fine," "Very Fine," and "Coarse" are all recognized USP terms for powders, but "Moderatly Fine" is not.

Drugs powders are usually not very potent because they are often diluted or mixed with other substances to create a more manageable dosage form. This is done to ensure that the drug can be accurately measured and administered to patients. Additionally, powders are often designed to be dissolved or mixed with a liquid before consumption, further reducing their potency. Therefore, it is generally true that drugs powders packed are usually not very potent.

Levigation is the technique that involves using a pad with a small amount of liquid to reduce particle size. It is commonly used in pharmacy and compounding to prepare suspensions or ointments. The liquid acts as a lubricant and helps in breaking down larger particles into smaller ones, resulting in a uniform mixture. Trituration involves grinding substances in a mortar and pestle, while pulverization refers to the process of reducing substances to a fine powder. Therefore, the correct answer is Levigation.

Topical preparations typically have a particle size ranging from 50 to 100 microns. This particle size range allows for effective absorption and penetration into the skin, ensuring proper delivery of the medication or active ingredients. Particles that are too small may be easily absorbed into the bloodstream, while particles that are too large may not be able to penetrate the skin barrier effectively. Therefore, the 50-100 micron range is considered optimal for topical preparations.

The correct answer is "None of the above" because none of the given definitions match the USP term correctly. The definitions provided for Very Coarse, Moderately Coarse, and Fine Powder do not align with the specified sieve sizes and percentages mentioned in the USP guidelines. Therefore, none of the options accurately represent the correct definition for the USP term.

Hygroscopic substances have the ability to absorb moisture from the air. This means that when exposed to humid conditions, these substances attract and retain water molecules from the surrounding environment. This property is useful in various applications such as preserving the quality of certain products, preventing moisture damage, and controlling humidity levels.

Eutectic mixtures are mixtures of two or more substances that have a specific composition where the proportion of components will result in the lowest possible melting point. This means that at this specific composition, the mixture will melt at a lower temperature compared to any other composition. Eutectic mixtures are important in various fields such as metallurgy, materials science, and pharmaceuticals, as they can be used to control the melting temperature and enhance the properties of the resulting material.

Comminution refers to the process of breaking down or reducing the particle size of a solid substance. This process aims to achieve a finer state of subdivision by using various techniques such as crushing, grinding, or milling. By reducing the particle size, the surface area of the solid substance increases, which can enhance its reactivity or improve its physical properties. Comminution is commonly used in industries such as mining, pharmaceuticals, and food processing to obtain smaller particles that are easier to handle or to increase the surface area for better mixing or dissolution.

Granules have good flow properties compared to powders, meaning they can be easily poured or transferred without clumping or sticking together. They are also stable both physically and chemically, ensuring their integrity and effectiveness over time. Granules have a lower tendency to cake in dispersions, meaning they are less likely to form lumps or solidify when mixed with liquids. Additionally, granules are easily wetted compared to powders, allowing them to quickly absorb and dissolve in liquids. Overall, these advantages make granules a preferred form of material in various industries and applications.
