How are drugs packaged to ensure integrity?

Drugs are packaged with childproof caps and placed in staple bags and bubble pack envelopes to ensure their integrity during transport and storage, as well as to enhance safety for consumers. The use of childproof caps serves to prevent accidental ingestion by children, a significant safety consideration in pharmaceutical packaging. Furthermore, staple bags and bubble pack envelopes provide additional protection against physical damage and environmental factors, which helps maintain the stability and efficacy of the medication.

This method of packaging not only complies with safety regulations but also supports quality assurance practices within the pharmaceutical industry. Proper packaging is crucial for protecting medications from moisture, light, and physical impacts, which can compromise their effectiveness.

The other options present less effective or inappropriate methods for ensuring drug integrity. Standard cardboard boxes alone do not provide the same level of safety features or protection as described in the correct answer. Shipping drugs loose compromises their safety and allows for increased risk of damage or contamination, while seals in opaque wrappers do not offer adequate protection from environmental factors or ensure child safety. Thus, the combination of child-resistant features and padded packaging provides a comprehensive solution for secure drug delivery.
