Basics of Iontophoresis [+ Example Calculations]

The video tutorial explains iontophoresis, a method for delivering drugs transdermally using electric fields. It covers the importance of matching drug charge with electrode charge for effective delivery, emphasizing local drug delivery to superficial tissues. The tutorial discusses the necessity of drug ionization and provides examples of commonly used drugs. It also outlines the parameters and safety considerations for iontophoresis, including current density and dosage calculations.

Describe the limitations of iontophoresis in terms of tissue penetration.

What is the significance of the drug's charge in iontophoresis?

How does iontophoresis compare to oral administration and intramuscular injections?
