10.下列何者不屬於解離性麻醉劑（dissociative anesthetics）？
(A)ketamine
(B)phencyclidine
(C)tiletamine
(D)chlorpheniramine

Dissociative anesthetics (e.g., ketamine) have been used extensively in veterinary medicine and may still be the most common class of anesthetics in use.

The first dissociative anesthetic used was phencyclidine hydrochloride (PCP, “angel dust”), which is no longer commercially available because of the abuse of this drug among humans.

Newer phencyclidine derivatives include ketamine hydrochloride and tiletamine hydrochloride.

Ketamine is also a drug of abuse in humans (“specialK”) and tiletamine is only marketed in combination with zolazepam under the trade name Telazol® or Zolatel®.

懶人包: 解離型麻醉劑=很飄很鬆，被作為毒品濫用，Phencyclidine 目前已不再做治療用途，江湖稱天使塵；Ketamine 通常和 Xylazine並用；Tiletamine 通常和 Zolazepam 並用 (Telazol)
