Which of the following is a common side effect of Ketorolac?

Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for its analgesic properties. One of the common side effects associated with Ketorolac is gastrointestinal irritation. This occurs because, like other NSAIDs, Ketorolac can affect the gastrointestinal mucosa, potentially leading to symptoms such as upset stomach, nausea, or more serious gastrointestinal complications like bleeding or ulcers.

The mechanism behind this side effect involves the inhibition of prostaglandins, which are compounds that help protect the stomach lining. By interfering with their production, Ketorolac can make the stomach more susceptible to damage from gastric acid. Understanding this side effect is crucial for monitoring patients receiving Ketorolac therapy, allowing for preventive measures to be implemented, such as advising the use of protective medications if necessary.

Other options such as high blood sugar, increased heart rate, and respiratory depression are not typical side effects of Ketorolac, aligning the answer back to gastrointestinal irritation as a well-documented concern when using this medication.
