Final answer:
A mucosal atomizer device (MAD) is used for the intranasal delivery of medication. For home administration of systemic infections, the oral route is preferred due to its convenience for self-administration.
Step-by-step explanation:
A mucosal atomizer device (MAD) is used to deliver certain medications via the intranasal route. This route allows for medication to be administered directly through the nose, absorbing through the mucous membranes and entering the bloodstream. This is different from the inhalation route, which involves breathing in substances through the mouth or nose, primarily into the lungs. The sublingual route is under the tongue, and transdermal route involves absorption through the skin.
When considering convenient home administration for systemic infection treatment, the oral route is usually preferred due to its ease and non-invasiveness, which allows patients to self-administer. Intravenous and other parenteral routes typically require a healthcare setting due to the need for sterile technique and equipment. Topical application is used for localized treatment on the skin and is not effective for systemic infections.
