Oral administration
Oral Administration
Oral administration is a route of administration where a substance is taken through the mouth. Many medications are taken orally because this route is convenient, safe, and economical.
Pronunciation
Oral: /ˈɔːrəl/ Administration: /ədˌmɪnɪˈstreɪʃən/
Etymology
The term "oral" comes from the Latin word "os, oris" meaning mouth. "Administration" is derived from the Latin word "administratio" meaning management or control.
Process
Oral administration involves the ingestion of medications through the mouth. The medication is then absorbed in the digestive system and enters the bloodstream. This process can take anywhere from 15 minutes to 2 hours, depending on the specific medication and individual factors.
Advantages and Disadvantages
Oral administration has several advantages, including ease of use, cost-effectiveness, and the ability to have a slow and steady release of medication into the bloodstream. However, it also has some disadvantages, such as the potential for gastrointestinal irritation and the first-pass effect, where the concentration of a drug is greatly reduced before it reaches the systemic circulation.
