Ensure that the hopper and feed shoe are correctly calibrated to accurately dispense powder into the die cavity.

Correct

Change the size of the punch used in the tablet press to a larger diameter to reduce weight variation.

Reduce the speed of the tablet ejection process to allow the tablets to settle before leaving the machine.

Explanation

Correcting the calibration of the hopper and feed shoe ensures that a consistent amount of powder is fed into the die cavity for compression, thereby reducing weight variation in the tablets. Increasing compression force may not address the root cause of the inconsistency, and changing the punch size could negatively affect tablet uniformity. Reducing ejection speed is not likely to help with weight consistency.

Question 18

Multiple choice

A research lab is conducting an evaluation of the effectiveness of their current rotary tablet press. They are particularly interested in how the compression behavior impacts the tablet characteristics such as hardness and disintegration time. In considering their findings, which factor would most significantly impact the relationship between compression force and tablet quality?

The press geometry and operator training do not directly influence the compression-force-to-tablet-quality relationship.

Question 19

Multiple choice

During the production of a new line of controlled-release tablets using a multi-station tablet press, an operator notices that the tablets produced exhibit inconsistent release profiles during testing. If the team seeks to identify the most critical variable affecting the release profile, which factor should they analyze first?

The uniformity of the powder blend prior to compression.

Correct

The design of the tablet press, notably the number of stations utilized in production.

The calibration of the tablet ejection mechanism to ensure proper release from the die.

The settings for the storage conditions of the finished tablets post-manufacturing.

Explanation

The uniformity of the powder blend is critical as inconsistencies can lead to variations in tablet density, which directly affects the controlled release profile. While the design of the press and ejection mechanisms may have roles in production efficiency, they are less directly related to the variability in drug release characteristics than the blend uniformity.

Question 20

Multiple choice

A regulatory body has raised concerns regarding the quality control measures for a new series of tablets produced by a company using a single punch press. Specifically, they are questioning potential variability in tablet weights. To ensure compliance and address these concerns effectively, what would be the most effective strategy to implement in the production process?

Implement a robust quality assurance process that includes random sampling of tablet weights throughout the production run.

Correct

Increase the production speed to minimize batch production time, thereby reducing the opportunity for defects.

Enhance operator training focused on machine settings, rather than ingredient quality control.

Explanation

Implementing a robust quality assurance process with random sampling allows for active monitoring of tablet weights during production, thereby ensuring that any issues can be quickly identified and rectified. While calibrations are important, they don’t directly address variability. Increasing production speed may exacerbate problems, and focusing only on operator training ignores fundamental quality control processes.
