Question 20

discuss electrode placement for iontophoresis

Answer 20

cathode should be larger

active electrode over area and dispersive away at a distance longer than smallest diameter of smallest electrode

Question 21

discuss use of other physical agents c iontophoresis

Answer 21

consider if HMP before or after bcs of inc circulation - ma wwash away lng sa blood yung medication

Question 22

discuss drug orientation c iontophoresis

Answer 22

dapat enough yun amount

Question 23

discuss simultaneous use of 2 drugs c iontophoresis

Answer 23

2 drugs might reax against each other or repel = ionohydrokinesis

only 1/10 effective

Question 24

exp dosage parameters for iontophoresis

Answer 24

intensity = 1-4 mA; max is 5 mA
duration = 20-40 mins

goal is 40 mA-min = 2mA for 20 mins or 4mA for 10 mins

Question 25

discuss safe current density for iontophoresis

drug allergies/ prior adverse reax

anesthetic on skin to be treated

recent scars

metal embedded on area to be treated

acute injury if may bleeding

cardiac pacemakers

over temporal and orbital areas
