How is medication absorbed via the oral route?

Medication is absorbed via the oral route primarily by swallowing. When a medication is taken orally, it enters the digestive system, where it is broken down by stomach acids and enzymes. This breakdown process allows the active ingredients of the medication to be absorbed through the gastrointestinal tract, particularly in the small intestine, where most absorption occurs.

Once absorbed, the medication then enters the bloodstream, allowing it to circulate throughout the body and reach the intended site of action. This method of administration is commonly used for many medications due to its convenience and ease of use compared to other routes.

The other methods of administration mentioned, such as applying to the skin, intravenous injection, and inhalation, involve different absorption mechanisms and routes entirely. Each of these methods serves specific purposes, but they do not relate to the oral absorption process.
