  1. 4. – Example of drug delivered via TDDS, often used for smoking cessation.
  2. 5. – Technique using mild electrical current to drive drug molecules across skin.
  3. 9. corneum – Outermost skin layer that acts as the main barrier to drug penetration.
  4. 10. – Movement of drug molecules through the layers of skin.
  5. 11. – Type of patch design where drug is stored in a liquid/gel compartment.
  6. 14. – Covering the skin to hydrate stratum corneum and enhance drug uptake.
  7. 15. – Substance that increases drug penetration through the skin.
Down
  1. 1. – Use of ultrasound waves to improve percutaneous drug delivery.
  2. 2. – Patch design where drug is dispersed in a polymer layer for release.
  3. 3. – Sticky component of patch that holds it to the skin and may contain drug.
  4. 6. – Tiny needles that create microchannels to improve skin absorption.
  5. 7. – Process of drug entering systemic circulation from the skin.
  6. 8. – Common form of TDDS applied on the skin surface.
  7. 12. – Patient guidance on proper patch use, rotation of sites, and safety.
