How do patches like nicotine patches actually work?

Question

I was going to start research on a patch for different diseases and other things and was wondering how these patches actually work to get the nicotine and stuff in the patch in the bloodstream.

Answer 1

The patch is soaked in some medication, nicotine in this example. The medication, and possibly a solvent to keep it in liquid form, soak through the skin and into the bloodstream. It's a slow, steady process, so it avoids the wide swings in blood concentration that often come with injected or oral administration at intervals of several hours.

Not all meds can pass through the skin, and not all meds work with solvents that can carry them through the skin.

Answer 2

The dermal route or on the skin is a effective route to administer medication. The skin absorbs the medicine and it is carried into the bloodstream and the body breaks it down. Drawbacks include the patches not sticking well on oily or hairy skin, peeling off, which can result in the patch not being absorbed well enough to be therapeutic

Answer 3

Our skin is not an impermeable barrier. It will allow chemical the pass through. The nicotine is absorbed the skin and is then absorbed by the blood.
