Medical devices and methods for rapid and efficient systemic
drug delivery via mucous membranes, particularly oral mucosae, are described. Use of such devices and methods are particularly easy for people without any
medical training to employ should they be called upon to provide emergency
medical treatment for a victim suffering from
anaphylactic shock,
opioid overdose, or other life-threatening events. In some embodiments, the device includes an applicator tip with a porous
application layer positioned on the end of an elongate
