What does the abbreviation "PO" indicate in medication administration?

The abbreviation "PO" stands for "per os," which is a Latin term meaning "by mouth." This term is commonly used in medical practice to indicate that a medication should be taken orally. Medications administered PO are typically in the form of tablets, capsules, or liquid solutions that the patient swallows. This route is significant because it impacts the absorption and efficacy of the medication, as it must pass through the digestive system before entering the bloodstream. Understanding this abbreviation is vital for pharmacy technicians, as they must accurately interpret and dispense medications according to prescriptions. The other options refer to different routes of administration, such as injections or topical applications, which do not involve oral intake.
