Eye iontophoresis is a noninvasive technique that uses a small electric current to enhance drug penetration into the eye. It offers a controlled and tolerable method for delivering desired drug doses.
In more detail:
-
Mechanism: Iontophoresis works by using a weak electrical field to drive charged drug molecules through the tissues of the eye, bypassing natural barriers that can limit drug absorption.
-
Non-invasive: Unlike injections, iontophoresis is applied topically using specialized electrodes, minimizing discomfort and risk of infection.
-
Controlled Delivery: The amount of drug delivered can be precisely controlled by adjusting the electrical current and treatment time.
-
Enhanced Penetration: It allows for better penetration of drugs into various parts of the eye, including the cornea, conjunctiva, and even deeper tissues like the retina.
-
Flexibility: Iontophoresis can be used to deliver a wide range of drugs, including antibiotics, anti-inflammatory agents, and anti-glaucoma medications.
In summary, eye iontophoresis is a promising drug delivery method offering a non-invasive, controlled, and effective way to enhance drug penetration into the eye, potentially improving treatment outcomes for various ocular conditions.
