Iontophoresis Electrodes | Ag/AgCl Drug Delivery Patches | TOP-RANK
Technical-grade iontophoresis electrodes for active transdermal drug delivery. Features Silver/Silver Chloride (Ag/AgCl) technology to ensure pH stability and controlled ion migration.
Product Overview
These are active transdermal delivery interfaces designed to facilitate the migration of ionized drug molecules across the skin barrier using low-intensity direct current (DC). Unlike passive patches, these electrodes utilize electrical repulsion to deliver localized medication. We supply these to B2B clinical providers for the treatment of inflammatory conditions and localized pain.
Key Features
-
Ag/AgCl Polarization Control
Standard carbon electrodes used with DC current cause rapid electrolysis of water, leading to extreme pH shifts at the skin interface. Our electrodes utilize a stabilized Silver/Silver Chloride (Ag/AgCl) coating. This chemistry acts as a reversible electrode, maintaining a neutral pH and preventing the chemical burns associated with non-buffered iontophoresis interfaces.
-
Hydrophobic Adhesive Barrier
Fluid migration into the adhesive border can lead to localized "shorts" and uneven drug delivery. We use a hydrophobic foam or PE carrier as a perimeter seal. This ensures the medication remains confined within the absorbent reservoir, maintaining the calculated drug concentration and current density throughout the procedure.
-
Calibrated Reservoir MVTR
The rate of ion migration is affected by the Moisture Vapor Transmission Rate (MVTR) of the backing material. We utilize a low-MVTR PET backing to prevent premature evaporation of the medication during therapy. This maintains the ionic strength of the solution, allowing for linear drug delivery over the entire treatment cycle.
Applications
Physical Therapy
Localized administration of dexamethasone or lidocaine for tendonitis, bursitis, and plantar fasciitis.
Sports Medicine
Accelerated recovery of acute inflammatory injuries.
Dermatology
Active delivery of aesthetic or therapeutic agents through the stratum corneum.
OEM & Private Label
We operate specialized manufacturing hubs in China and Vietnam to support global B2B supply chains and mitigate Section 301 tariffs.
- Custom Sizes: Tooling available for "Runway Round," Rectangular, or Square reservoir geometries.
- Packaging: Individual sterile-barrier foil pouches or bulk non-sterile clinical packs.
- Logistics: Private label branding on pouches and master cartons with integrated QC batch tracking.
Certifications
Regulatory: FDA 510(k), CE (MDR), and UKCA documentation ready for verification.
Systems: ISO 13485 and MDSAP audited.
QC Protocols: Every batch is tested for reservoir absorption capacity, Ag/AgCl coating continuity, and adhesive peel strength.
FAQ
Q: Why is Ag/AgCl mandatory for drug delivery but not for TENS?
A: TENS uses AC (alternating current), which does not cause significant ion accumulation. Iontophoresis uses DC (direct current). Without Ag/AgCl, the DC current will create acidic or alkaline environments on the skin, causing severe chemical burns within minutes.
Q: Can the reservoir be pre-filled?
A: Most B2B clinical versions are supplied dry to allow the clinician to add the specific prescribed medication. However, we offer OEM development for pre-filled stable aqueous solutions under specific regulatory filings.
CTA
B2B project managers can request technical drawings and Ag/AgCl stability test data for qualification.
