1

What is ionotophoresis?

A local transfer of substances into the skin using electrical energy

2

What is an advantage of administering something with ionotophoresis?

It bypasses the digestive system and isn't as invasive as a needle

3

What is the main disadvantage of ionotophoresis?

It is limited to the superficial tissues (stratum corneum mostly)

4

What type of current is ionotophoresis?

Continuous and monophasic

5

How does ionotophoresis work with regard to charges?

Drug/solution polarity is matched to the polarity of the electrode, this repels the the solution away from the electrode into the skin

6

Does amplitude govern how far the drug penetrates?

No, rather how fast it gets there

7

What determines how far the drug goes after delivery?

Passive diffusion

8

By virtue of being direct current, what other effect does direct current on the tissue?

An electrolytic effect

9

What type of electrolytic product is created under the anode?

HCl

10

What effects does HCl have on tissue?

A sclerotic effect

11

What type of electrolytic product forms under the cathode?

NaOH

12

What effects does NaOH have on tissue?

Sclerolytic or softening effect

13

By virtue of producing redox products of HCl and NaOH, what also changes in the skin tissue?

pH

14

What concentrations of aqueous solution should be administered? Ointment?

2-5%, 1-5%

15

What is one way to minimize the side-effects of electrolysis?

Use a buffered electrode

16

What condition has tap water Ionotophoresis been shown to be an effective treatment of?

Hyperhidrosis

17

What other conditions is there moderate support for use of ionotophoresis?

Rheumatoid disorders, epicondylitis, Peyronie's disease, TMJ disorder, and calcifying tendinitis
