15. About the intrathecal drug delivery system, which of the following statements is NOT correct?
(A) It places medication directly into the cerebrospinal fluid that surrounds the spinal cord.
(B) Morphine delivered directly to the intrathecal space is particularly effective because it does not have to circulate systemically to reach the CSF and the dorsal horn of the spinal cord.
(C) As a result, much smaller doses are needed (e.g., approximately 1/30 of an oral morphine dose), and the frequency of side effects is reduced.
(D) Advantages of intrathecal therapy in pain includes effective pain relief, reduced side effects for patients, reduced consumption of systemic medication, improved ability to perform ADLs, and enhanced quality of life.
