Ketorolac, a non-steroidal anti-inflammatory drug (NSAID), offers potent analgesic benefits, making it effective in managing pain and reducing reliance on opioids. Its efficacy is notable in treating prostaglandin-mediated uterine cramps. However, its use is contraindicated in individuals with asthma due to the risk of precipitating bronchospasm by interfering with prostaglandin pathways. Ketorolac also carries risks of renal impairment, gastritis, and peptic ulceration with prolonged use.
The opioid-sparing effect of ketorolac has been linked to a decreased cancer recurrence rate following breast cancer surgery. However, it is advised against in cases requiring bone fusion post-back surgery due to its interference with bone healing. Caution is also advised when considering ketorolac for elderly patients with pre-existing renal issues. Contrary to long standing beliefs about NSAIDs increasing surgical bleeding risk, recent studies, including those by Gobble et al., Richardson et al., and Stephens et al., have demonstrated that ketorolac does not significantly increase the risk of incisional or gastrointestinal bleeding in patients under 75 years old, as well as in pediatric neurosurgery and plastic surgery patients. These findings suggest a reassessment of the risks associated with ketorolac, emphasizing its safe use under appropriate conditions and patient populations.
| Situation | Guidance |
|---|---|
| Asthma | Contraindicated — risk of precipitating bronchospasm through interference with prostaglandin pathways |
| Prolonged use | Risk of renal impairment, gastritis, and peptic ulceration |
| Bone fusion after back surgery | Advised against — interferes with bone healing |
| Elderly with pre-existing renal disease | Use with caution |
| Prostaglandin-mediated uterine cramps | Notably effective |
| Breast cancer surgery | Its opioid-sparing effect has been linked to a decreased cancer recurrence rate |
| Patients under 75 years | Does not significantly increase incisional or gastrointestinal bleeding risk |
| Pediatric neurosurgery and plastic surgery | No significant increase in bleeding risk demonstrated |
