In medical terminology, "PR" stands for "per rectum," which refers to the route of administration for medications or treatments that are given rectally. This method is often used when oral administration is not feasible, possible, or when a rapid onset of action is desired. Medications that are administered per rectum can be absorbed quickly through the rectal mucosa, providing effective results, especially in cases such as nausea, vomiting, or in patients who are unable to take medications orally.

Other options listed, such as "per year," "per request," and "peripheral," do not accurately reflect the use of "PR" in medical contexts. "Per year" would typically be abbreviated as "per annum," while "per request" is not a standard abbreviation and is not commonly recognized as "PR." Additionally, "peripheral" relates to intravenous administration via peripheral veins but is not abbreviated as "PR." Thus, understanding the established terminology helps clarify the appropriate use of medical abbreviations in practice.
