**Core Concept**
Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that is used for its analgesic and anti-inflammatory properties. The key difference between ketorolac and aspirin lies in their pharmacokinetic profiles and clinical uses.
**Why the Correct Answer is Right**
Ketorolac has a higher potency and more rapid onset of action compared to aspirin, making it a suitable alternative for short-term pain management. This is due to its higher affinity for cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, which are responsible for the production of prostaglandins. By inhibiting these enzymes, ketorolac effectively reduces pain and inflammation with minimal gastrointestinal side effects.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because ketorolac does not have a longer duration of action compared to aspirin.
**Option B:** This option is incorrect because ketorolac is not more effective in reducing inflammation compared to aspirin.
**Option C:** This option is incorrect because ketorolac is not more easily absorbed compared to aspirin.
**Clinical Pearl / High-Yield Fact**
