    What is comminution?

    Explanation
    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.

    What is Euectic Mixtures

    Explanation
    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.

    What is hygroscopic?

    Explanation
    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.

    Rate this question:

  • 5. 

    Which USP term matches with its correct definition?

    • Very Coarse - All powder particles pass througha No. 8 sieve and not more than 40% pass through No. 60 sieve

    • Moderately coarse - All powder particles pass througha No. 40 sieve and not more than 40% pass through No. 60 sieve

    • Fine Powder - All powder particles pass througha No. 60 sieve and not more than 40% pass through No. 80 sieve

    • All of the above

    • None of the above

    Correct Answer
    A. None of the above
    Explanation
    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.

    What is the particle size of topical preparations?

    • 0.5 - 10 microns

    • 50 - 100 microns

    • 1-5 microns

    • 10-50 microns

    Correct Answer
    A. 50 - 100 microns
    Explanation
    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.

    Rate this question:

  • 7. 

    Which technique involves using a pad with a small amount of liquid to reduce particle size?

    • Trituration

    • Levigation

    • Pulverization

    • All of the above

    • None of the above

    Correct Answer
    A. Levigation
    Explanation
    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.

    Drugs powders packed are usually not very potentent?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    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.

    Which is not a USP term for powders?

    • Fine

    • Very Fine

    • Coarse

    • Moderatly Fine

    Correct Answer
    A. Moderatly Fine
    Explanation
    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.

    Which is an advantages of Powders?

    • No difficulty swallowing

    • Easy to adjust dose

    • Rapid onset of action

    • All the above

    • None of the above

    Correct Answer
    A. All the above
    Explanation
    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.

    Rate this question:

  • 11. 

    When making powders there is a manufactoring epense because of individaully wrapped powder ddoses?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    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.
