IONTOPHORESIS Flashcards
Iosone Law
- Medications are ionically active
- Electrically charged electrode will repel similarly charged
Driving force in iontophoresis
Electrostatic repulsion
The force acting to move the ion through the body
surface depends on:
o Strength of electric field/intensity of the
electricity applied
o Impedance of the tissues to the current flow
o Current density is also responsible for the
velocity on how we deliver these charged
ions inside the body
o Current density is increased by decreasing
the electrode size or by increasing the
current intensity applied to the pt
Principles of ion transfer
- Ionization
- Electromigration/ Law of Attraction
- Deeper penetration of drug vs topical administration
- Bypasses the systemic route vs oral ingestion of
medication - Non-invasive vs administration using injections
