Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) with analgesic properties. It is used for short term management (up to 5 days) of moderately severe acute pain.


  • Moderately severe acute pain
  • Headache
  • Acute pain requiring opioid-level analgesia

Pharamcological Action

Ketorolac inhibits prostaglandin synthesis by competitive blocking cyclooxygenase (COX) enzyme. The prostaglandins cause the redness, fever, swelling, pain, and inflammation.


Patients aged 17 to 64 years require 20 mg PO once followed by 10 mg every 4 to 6 hours as recommended. Patients aged >65 years, those with renal impairment, and/or weight <50 kg require 10 mg PO once followed by 10 mg every 4 to 6 hours as recommended.


Ketorolac is rapidly absorbed, Cmax (maximum peak concentration) being achieved between 20 to 60 minutes. Its bioavailability is estimated to range from 80 to 100%. The drug is extensively bound (>99%) to plasma proteins and has a volume of distribution (0.1 to 0.3 L/kg) comparable with those of other NSAIDs. Ketorolac is extensively metabolized through glucuronidation and oxidation; little if any drug is eliminated unchanged. The elimination half-life is between 4 and 6 hours.

Clinic Evidence

  • Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) with strong analgesic activity that has been evaluated in postoperative setting, in both hospital inpatients and outpatients. Ketorolac provides relief from mild to severe pain in patients after major abdominal, orthopedic or gynecological surgery or ambulatory laparoscopic or gynecological procedures and also provides a useful alternative, or adjuvant, to opioids1.
  • Ketorolac tromethamine controls postoperative pain better than Hydrocodone and Acetaminophen after anterior cruciate ligament reconstruction. With an effective loading dose administered before the subsequent oral dosage, better reduction in pain is there with Ketorolac tromethamine as compare to Hydrocodone and Acetaminophen2.
