This really is made use of when the drug's molecular sizing is simply too significant for being correctly absorbed while in the intestinal tract or when much better bioavailability or a quicker absorption charge is needed when compared to the oral route.

The blood-Mind barrier is A significant obstruction on the shipping of drugs into the central nervous program.
