Heres some work i dug up from last year, hope it helps.


1. How does a subdermal implant deliver medication to the bloodstream?
A subdermal implant consists of a small silicone tube which contains a limited supply of the required medication. Usually for convieniece this supply lasts for a number of years. The tube is inserted into the body at a point where it is safe to stay under the skin, but can still access the bloodstream. From here, it releases the required amount of medication into the blood, and is replaced as soon as it is spent.


2. How does the design of the implant ensure that the correct dose of drug is released?
It is composed of a tube with a very small opening, which only allows very small amounts of chemical to be exerted at a time, meaning that it is possible to confiegure the tube to administer the required doseage.

3. What drugs are delivered this way, and why are these methods favoured for delivery of these particular drugs?
The most common drug used as a subdermal implant is a contraceptive for women (Levonorgestrel). It is put into a tube and inserted near the hormone receptor, which modifies the way in which it works.
