What is the purpose of humidity control in sterile compounding rooms?

The purpose of humidity control in sterile compounding rooms is primarily to maintain drug stability and quality. In sterile environments, excessive moisture can lead to various problems, including the degradation of certain active pharmaceutical ingredients and the potential for microbial growth. High humidity levels can adversely affect the physical and chemical properties of the compounded preparations, potentially compromising their effectiveness and safety.

By controlling humidity, the environment significantly contributes to the integrity and reliability of the compounded sterile products. For instance, many sterile products have specific storage conditions that include limits on humidity, which must be closely monitored and maintained to ensure compliance with standards for sterile compounding.

The other options focus on aspects that are important in their own right but do not specifically address the critical role of humidity in maintaining the quality of compounded medications.
