Morphine and hydromorphone (Dilaudid) are two types of opioid receptor agonists used for pain management. Hydromorphone is a more potent drug than morphine, and lower doses are needed to control pain
How do actions at receptor sites explain this difference? a. Morphine remains bound to opioid receptors longer than hydromorphone does.
b. Hydromorphone remains bound to opioid receptors longer than morphine does.
c. Morphine is metabolized and eliminated at a faster rate than hydromorphone.
d. Hydromorphone is metabolized and eliminated at a faster rate than morphine.
B
The length of time and intensity of an agonist drug's response is related to how tightly and how long it remains bound to its receptors. More potent agonist drugs stay bound longer than do weaker agonist drugs.
