Efficacy
คำจำกัดความ
The maximum therapeutic effect a drug can produce, regardless of the dose given. A drug with higher efficacy can achieve a greater maximum response than one with lower efficacy, even if the latter is more potent.
ตัวอย่าง
Morphine (full opioid agonist) has greater analgesic efficacy than buprenorphine (partial agonist) — morphine can produce a stronger maximum pain relief.
