Bioactive agents are cutaneously delivered by a jet dispenser using inkjet
technology, such as that used in printing. The dispenser propels precise
volumes of bioactive agent toward the skin, where they exert a local or
topical effect, or move through the skin for transdermal systemic
delivery. Drugs are either delivered directly to the skin, or are
introduced into a transdermal patch, which may receive repeated dosages.
A controller in the dispenser may control delivery of multiple different
drugs, timing of drug administration, or change drug regimens in response
to a changing medical condition of a patient, such as those monitored by
a sensor in communication with the controller, for example to prevent an
overdose. The dispenser may act as an electromechanical patch, capable of
long term administration of drugs to the skin, to achieve local or
systemic pharmaceutical effects. Administration methods are also
provided, along with replacement kits.
