PER OS Meaning and
Definition
-
Per os (abbreviated as PO) is a Latin term frequently used in medicine and pharmacology, and it translates to "by mouth" or "through the mouth" in English. It refers to the route of administration of a medication or substance that is taken via the mouth, usually in the form of tablets, capsules, liquids, or powders that are ingested orally.
When a medication is prescribed "per os," it implies that it is intended to be swallowed and absorbed through the gastrointestinal tract. This route of administration allows the medication to be absorbed into the bloodstream through the lining of the stomach or intestines, thus facilitating systemic distribution to various body tissues.
The per os route is widely used because it is convenient and non-invasive, often providing a simple and effective means of drug delivery. It is particularly suitable for medications that can withstand the acidic environment of the stomach and can be readily absorbed through the gastrointestinal mucosa. However, it is worth noting that certain medications may have a lower bioavailability when taken per os due to potential interactions with food or the first-pass metabolism in the liver.
In summary, per os is a Latin term commonly used in medicine to indicate that a medication or substance should be administered by mouth. It is widely employed due to its simplicity, convenience, and ability to facilitate systemic drug distribution.
