What does the term "PO" specifically refer to?

The term "PO" is an abbreviation derived from the Latin term "per os," which translates to "by mouth." When a medication is administered PO, it means that it is given orally, allowing it to be absorbed through the digestive system. This route is commonly used for various medications in both human and veterinary medicine due to its convenience and ease of administration.

Oral administration of medications is beneficial because it tends to be more comfortable for the patient and can often be safer and less invasive compared to other routes. It’s also preferable in many cases, as it allows for self-administration in some situations and can facilitate a gradual absorption into the bloodstream, resulting in more stable drug levels.

Recognizing the significance of this terminology is crucial for anyone working in a veterinary environment, as accurate understanding and communication about medication routes are vital for effective treatment of animals.
