Which statement is true if 10 mg of oxycodone produces a greater analgesic response than does aspirin at any dose?

Oxycodone producing a greater analgesic response than aspirin at any dose indicates that it has a higher efficacy for pain relief. Efficacy refers to the maximum effect that a drug can produce, regardless of the dose administered. In this case, even a relatively low dose of oxycodone (10 mg) is capable of surpassing the analgesic effect of aspirin, which suggests that oxycodone can produce a stronger effect compared to aspirin. Therefore, the statement that oxycodone is more efficacious than aspirin is substantiated by the observed analgesic outcomes, highlighting its ability to provide a higher level of pain relief.

The other options are less accurate in describing the relationship between the two drugs. Potency involves the amount of drug needed to achieve a certain effect, while efficacy specifically refers to the maximum effect achievable; thus, stating that oxycodone is less potent would not align with the information provided. The characterization of oxycodone as a partial agonist versus aspirin as a full agonist does not directly relate to their comparative efficacy in this context. Moreover, the assertion that both drugs act on the same target would not hold in the face of their differing mechanisms and therapeutic uses.
