Practice Question

What is the effect of combining meperidine and promethazine for pain control postoperatively?

Answer Choices:

Correct Answer:

Synergistic effect

Rationale:

💊Meperidine (Demerol) is an opioid analgesic, while promethazine (Phenergan) is an antihistamine with sedative properties.

🌀Together, they produce a synergistic effect, where combined action is greater than either drug alone.

😴Promethazine enhances pain control and sedation, reducing the need for higher opioid doses.

📋This combination is often used to improve comfort and reduce nausea in postoperative patients.

📌Core Message

Combining meperidine and promethazine produces a synergistic effect, enhancing pain relief and sedation.
