Which of the following drugs is exempt from the Poison Prevention Packaging Act (PPA)?

The Poison Prevention Packaging Act (PPA) was enacted to protect children from accidental ingestion of hazardous substances by requiring child-resistant packaging for many household products and medications. However, certain substances are exempt from these regulations.

The correct answer indicates that none of the drugs listed are exempt, which aligns with current regulations that stipulate most over-the-counter medications, such as ibuprofen and acetaminophen (APAP), do not fall under the exempt category. In fact, these medications must adhere to the PPA requirements due to their potential risk to children.

Understanding the importance of child-resistant packaging, it's clear that the PPA aims to minimize accidental poisonings, thus emphasizing the need for compliance among various drug classes, including those commonly used for pain relief.
