|Iontophoresis facilitates delivery of medications
into the tissues beneath the skin by electronic transport
of ionized drugs in solution. Acetic acid iontophoresis
is effective in the treatment of heel pain. Iontophoresis
of dexamethasone for plantar fasciitis should be considered
when more immediate results are needed. Iontophoresis
has also been used to successfully treat plantar hyperhidrosis.
Phonophoresis is a technique that combines topical
drug therapy with ultrasound to achieve therapeutic
drug concentrations in muscle and other tissues beneath
the skin. Ultrasound gels can be formulated to contain
medications such as anti-inflammatories and/or anesthetics.
