Baclofen has good bioavailibility, but generally BA is determined by measuring the amount of drug absorbed into the bloodstream and not i.e. the brain or CSF.
Wiki sez: Intrathecal pumps offer much lower doses of baclofen because they are designed to deliver the medication directly to the spinal fluid rather than going through the digestive and blood system first. They are often preferred in spasticity patients such as those with spastic diplegia, as very little of the oral dose actually reaches the spinal fluid.
Likewise, intrathecal morphine is actually more effective than even IV morphine, again because only a portion of an administred dose crosses BBB and makes it to the brain/spinal cord.
There is also the benefit of not requiring to repeatedly dose oral medications, an intrathecal pump can provide constant levels of drug even when you're asleep.
