Ketorolac
Short-term potent NSAID used for moderate to severe acute pain.
NSAID
Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID) primarily indicated for the short-term management of moderate to severe acute pain. It is often used in postoperative settings, acute musculoskeletal injuries, and situations where strong non-opioid analgesia is required. Because of its high analgesic potency, ketorolac is generally reserved for short-duration therapy under medical supervision.
The medication works by strongly inhibiting cyclooxygenase enzymes, leading to a marked reduction in prostaglandin-mediated pain and inflammation. Its analgesic effect is considered comparable to some opioid medications for certain types of acute pain, which makes it valuable in carefully selected patients.
Ketorolac is available in oral and injectable formulations. Due to its safety profile, total duration of therapy is typically limited to a maximum of 5 days. Prolonged use significantly increases the risk of serious gastrointestinal, renal, and bleeding complications, which is why strict adherence to recommended duration is essential.
Common side effects include gastric discomfort, nausea, dizziness, and drowsiness. Patients with a history of peptic ulcer disease, renal impairment, or bleeding disorders require special caution. When used appropriately for short-term pain control, ketorolac provides powerful non-opioid analgesia with predictable clinical benefit.
