Advantage of tiletamine-zolazepam over ketamine?

• A. The combination is very potent and a small volume can completely anesthetize a patient
• B. It has a long duration
• C. It cannot be administered IM
• D. It lacks analgesia

Answer: (A)

The main concept here is that the combination of tiletamine and zolazepam is highly potent, so a very small injection volume can achieve complete anesthesia. This high potency makes dosing more convenient, especially in small patients or when injection volume is a limiting factor, compared with ketamine, which generally requires a larger volume to reach similar anesthetic depth.

Telazol is formulated for intramuscular use, so the statement that it cannot be given IM is not true. It also provides some analgesia, thanks to tiletamine, and the benzodiazepine component adds sedation and muscle relaxation, which contributes to smoother induction and recovery. The option claiming a longer duration is not the primary or consistent advantage, and the idea that it lacks analgesia is inaccurate.
