What method is used for administering internal medications?

Administering internal medications typically involves delivering the medication through oral ingestion or inserting it directly into the gastrointestinal (GI) tract. This method ensures that the medication is absorbed effectively into the system to produce the desired therapeutic effects. When medications are taken orally, they are usually swallowed and absorbed through the stomach and intestines.

Alternatively, medications can also be administered rectally, bypassing the digestive tract and systemic circulation, providing quick relief for certain conditions. This route is vital when patients are unable to take medications orally due to vomiting or difficulty swallowing.

The other methods mentioned in the choices do not align with the typical approach for internal medication administration. Applying medication to the skin pertains to topical treatments, while injecting into the muscle is a form of parenteral administration. Inhalation via a nebulizer targets the respiratory system rather than entering the GI tract. Understanding the nature and method of medication administration is crucial for ensuring effective treatment outcomes.
