Oral administration of a liquid

Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example.[1]

Terminology

Per os (; P.O.) is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not used in the mouth such as, for example, caries prophylaxis).[2] The abbreviation P.O. is often used on medical prescriptions.

Scope

Oral administration includes:

Enteral medications come in various forms, including[1] oral solid dosage (OSD) forms:[3]

  • Tablets to swallow, chew or dissolve in water or under the tongue
  • Capsules and chewable capsules (with a coating that dissolves in the stomach or bowel to release the medication there)
  • Time-release or sustained-release tablets and capsules (which release the medication gradually)
  • Powders or granules

and oral liquid dosage forms:[4]

  • Teas
  • Drops
  • Liquid medications or syrups

Facilitating methods

Concomitant ingestion of water facilitates in swallowing tablets and capsules.[5] If the substance has disagreeable taste, addition of a flavor may facilitate ingestion.[5] Substances that are harmful to the teeth are preferably given through a straw.[5]
