What is one of the purposes of nasal medications?

Nasal medications serve multiple purposes, and one significant purpose is to produce both local and systemic effects. When administered nasally, the medication is absorbed through the mucous membranes into the bloodstream, allowing for direct entry into circulation. This route can lead to rapid onset of action for systemic effects such as pain relief, hormone administration, or other therapeutic effects.

In addition, nasal medications can also target local sites, such as in the case of nasal decongestants for relieving nasal congestion or local anesthetics for localized pain relief. This dual capacity makes nasal administration an effective route for various therapeutic interventions.

Other options do not accurately represent the functions of nasal medications. For instance, injecting medications is not related to nasal administration, which instead utilizes the nasal mucosa for absorption. Clearing out the digestive system is unrelated, as nasal medications focus on the respiratory system and systemic delivery. Lastly, while some medications might have effects on fever and body temperature regulation, this is not a primary purpose of nasal medications as a whole.
