ES for iontophoresis Flashcards
exp the concept of iontophoresis
topically applied medication c physiologically active ions vua cont DC
exp iosone law
elec charged electrode will repel same charge ion = electrostatic repulsion
what is the driving force in iontophoresis
electrostatic repulsion
what are the principles or advantages of ion transfer
ionization - dissolve in water
electromigration/law of attraction
deeper penetration
bypasses systemic route
non-invasive
what are the medicines with (+) charge
copper sulfate
wydase
magnesium sulfate
xylocaine/lidocaine
zinc oxide
what electrode should be used for (+) medicines
anode as active electrode since +
what are the medicines with (-) charge
acetic acid
sodium chloride
decadron
iodine
sodium salicylate
what is the charge of tap water
- or +
indications of copper sulfate
fungal infections
indications of wydase
edema reduction
indications of magnesium sulfate
muscle relaxant or vasodilator
indications of Xylocaine or Lidocaine
local anesthetic for trigger points, bursitis and neuritis
indications of zinc oxide
dermal ulcers; slow healing of wound
indications of acetic acid
calcium deposits
indications of sodium chloride
soften scar adhesions; sclerosis
indications of decandron
MSK inflammation
indications of iodine
scar
indications of sodium salicylate
MSK inflammations; plantar warts
indications of tap water
hyperhidrosis
discuss electrode placement for iontophoresis
cathode should be larger
active electrode over area and dispersive away at a distance longer than smallest diameter of smallest electrode
discuss use of other physical agents c iontophoresis
consider if HMP before or after bcs of inc circulation - ma wwash away lng sa blood yung medication
discuss drug orientation c iontophoresis
dapat enough yun amount
discuss simultaneous use of 2 drugs c iontophoresis
2 drugs might reax against each other or repel = ionohydrokinesis
only 1/10 effective
exp dosage parameters for iontophoresis
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
discuss safe current density for iontophoresis
cathode - 0.5 mA/cm^2
anode - 1.0 mA/cm^2
contraindications 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
