What does the abbreviation "PR" imply regarding administration route?

The abbreviation "PR" stands for "per rectum," which indicates that a medication is to be administered rectally. This administration route is often used for medications that need to be absorbed quickly or for patients who may have difficulty taking medications orally due to vomiting, difficulty swallowing, or when rapid systemic absorption is desired.

Medications given rectally can include suppositories, enemas, or liquid forms, and this method can provide an effective alternative mode of drug delivery, particularly for certain types of medications or specific clinical scenarios. Understanding the abbreviation "PR" is essential for healthcare professionals to ensure proper medication administration and patient safety.
