Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: The pressure filling method for filling pharmaceutical aerosol is usually preferred over cold filling method 
Reason R: Because with pressure filling method high production speed can be achieved and less propellant is lost. 
In light of the above statements, choose the correct answer from the options given below

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The Correct Option is A

The given question involves an Assertion (A) and a Reason (R) related to pharmaceutical aerosol filling methods. Let's analyze both statements to determine the correct answer.

1. Assertion (A): The pressure filling method for filling pharmaceutical aerosol is usually preferred over the cold filling method.
2. Reason (R): Because with the pressure filling method, high production speed can be achieved and less propellant is lost.

To evaluate these statements, we need to understand the context of pharmaceutical aerosol filling methods:

Conceptual Explanation:

• Pressure Filling Method: This method involves mixing the product concentrate with the propellant under pressure. It is efficient, minimizes propellant loss, and is well-suited for heat-sensitive substances since it doesn’t require exposure to cold temperatures.
• Cold Filling Method: Involves chilling both the propellant and concentrate to very low temperatures. This method might lead to condensation and loss of propellant and is typically slower.

Analysis of Assertion and Reason:

• Assessment of Assertion (A): The pressure filling method is indeed preferred over the cold filling method due to its efficiency and suitability for heat-sensitive materials.
• Assessment of Reason (R): The reason provided is correct. The pressure filling method allows for high production speeds and reduces propellant loss, which are primary advantages.
• Correlation between A and R: Reason (R) clearly explains why Assertion (A) is true. The advantages noted in R (high production speed and decreased loss of propellant) are directly linked to the preference mentioned in A.

Conclusion:

After evaluating both statements and their relationship, we find that both Assertion (A) and Reason (R) are true. Moreover, Reason (R) is the correct explanation for Assertion (A) because it directly states the benefits that make the pressure filling method preferable.

Therefore, the correct answer is: "Both A and R are true and R is the correct explanation of A."
