Administration of Drugs.
The route of administration of a drug is very important in determining the rate and completeness of its absorption into the blood stream and speed and duration of the drug’s action in the body.
Oral Administration.
The route of administration is by mouth. Drugs given orally must pass into the stomach and be absorbed into the blood stream through the intestinal wall. This method may have several disadvantages. If the drug is destroyed in the digestive tract by the digestive juice or if the drug cannot pass through the intestinal wall or mucosa, it will be ineffective.
