PO stands for which route?

Explanation:
In pharmacology, abbreviations for routes of administration are used to tell how a drug is given. PO stands for per os, a Latin term meaning by mouth, so it denotes oral administration. When a medication is taken by mouth, it’s swallowed and absorbed through the digestive system, with possible influences from food and first-pass metabolism in the liver. This differs from other routes: intravenous means into a vein, inhalation is through the lungs, and topical is applied to the skin or mucous membranes. Therefore, PO indicates the drug should be taken by mouth.
