Pharmaceutical Technology MCQ Quiz

The correct answer is "Two of the mentioned choices." This means that two of the labels mentioned in the options are the main labels for sulfur cream preparation. Without knowing the specific labels mentioned, it is not possible to provide a more detailed explanation.

To prepare 50 g of a 5% sulfur cream, we need to determine the amounts of sulfur powder and cold cream required. Since the cream is 5% sulfur, it means that 5% of the total weight (50 g) should be sulfur powder.

Therefore, 5% of 50 g is 2.5 g. So, we need 2.5 g of sulfur powder. The remaining weight should be cold cream, which is 50 g - 2.5 g = 47.5 g.

Hence, the correct answer is 2.5 g of sulfur powder + 47.5 g of cold cream.

The correct answer is "Two of the choices." This means that two of the statements provided are correct about cocoa butter suppository base. The other statements may be incorrect or incomplete.

The correct answer is "None of the choices." This means that all of the options listed (preservative, coloring agent, sweetening agent, and suspending agent) are considered additives in a pharmaceutical suspension.

To dilute a cream from 0.05% to 0.01% concentration, a larger amount of diluent is needed. In this case, the correct answer of 150 g suggests that 150 g of cold cream is required to dilute 30 g of the 0.05% clobetasol propionate cream to achieve the desired 0.01% concentration.

This statement is correct because semisolid preparations like creams can have solid active ingredients incorporated into them either during the preparation process or after the cream has been prepared using a tile and spatula. This allows for flexibility in formulating creams with solid ingredients.

Granulation is not a step for the incorporation of a drug into a semisolid product. Granulation is a process used in solid dosage form manufacturing, where the drug and other excipients are mixed and moistened to form granules. In semisolid products, such as creams or ointments, the drug is typically dispersed or dissolved in a base or vehicle, and granulation is not necessary. Weighing of the drug, mixing, and size separation are all important steps in the incorporation of a drug into a semisolid product.

The correct answer is 2 and 3. In the fusion method for creams preparation, the oily phase is melted in a water bath at 70°C. This is done to ensure that the oily phase is fully melted and can be easily incorporated into the cream. The aqueous phase should also be heated in a water bath at the same temperature as the oily phase. This is important to ensure that both phases are at the same temperature when they are mixed together, which helps in achieving a stable emulsion. After mixing the two phases, the cream must be cooled gradually to prevent the separation of solid materials and to maintain the stability of the emulsion. It is not necessary to mix the components vigorously to prevent cracking of the emulsion.

Tap water could not be used to reconstitute suspension powder because it may contain impurities or additives that could affect the stability or efficacy of the powder. Freshly boiled and cooled clean water and freshly purified H2O are both suitable options for reconstitution as they are free from contaminants. The measured volume of water provided with the product ensures accurate reconstitution. Therefore, tap water is the only option that should not be used.

Salicylic acid is not typically used as an anti-scabies agent. Scabies is a skin infestation caused by mites, and it is usually treated with medications such as permethrin or ivermectin. Salicylic acid is commonly used as a keratolytic agent, which helps to remove dead skin cells and treat conditions like acne, corns, and warts. However, it is not effective in treating scabies.

The correct answer is that Sodium Lauryl Sulfate will react with the free fatty acids of white beeswax to produce an emulsifying agent. This means that Sodium Lauryl Sulfate plays a role in the formulation of vanishing cream by helping to create a stable emulsion between the oil and water components. It is not incorrect regarding vanishing cream formula preparation.

The question states that the weight of one medicated suppository is 1.2 g. Since the medicated suppository contains 30% of Drug A, the remaining 70% must be cocoa butter. Therefore, the weight of cocoa butter in one medicated suppository is 0.75 * 1.2 g = 0.9 g.

To prepare 4 non-medicated suppositories, we need to calculate the theoretical weight of cocoa butter needed. Since each medicated suppository contains 0.9 g of cocoa butter, the weight of cocoa butter needed for 4 non-medicated suppositories would be 4 * 0.9 g = 3.6 g.

However, the given answer is 3.36 g, which is the closest option to 3.6 g. Therefore, the correct answer is 3.36 g.

Cetyl Alcohol does not work as an auxiliary emulsifying agent in vanishing cream formula.

Spermaceti was used as a stiffening agent in cold cream preparation.
