Ketorolac, an injectable nonnarcotic analgesic

Area of Science:

• Pharmacology
• Pain Management
• Drug Efficacy

Background:

• Ketorolac tromethamine is an injectable nonsteroidal anti-inflammatory agent (NSAIA).
• Its mechanism involves inhibiting prostaglandin synthesis, leading to anti-inflammatory, analgesic, and antipyretic effects.
• Clinical studies review its chemistry, pharmacology, pharmacokinetics, interactions, and adverse effects.

Purpose of the Study:

• To review clinical studies on ketorolac tromethamine.
• To describe its properties, including chemistry, pharmacology, pharmacokinetics, drug interactions, and adverse effects.
• To evaluate its efficacy and safety for pain management.

Main Methods:

• Review of clinical studies on ketorolac tromethamine.
• Description of its pharmacological and pharmacokinetic properties.
• Analysis of its efficacy and safety profile compared to other analgesics.

Main Results:

• Ketorolac tromethamine demonstrates anti-inflammatory, analgesic, and antipyretic activity, primarily through prostaglandin synthesis inhibition.
• It provides effective relief for moderate to severe postoperative pain, renal colic, trauma, and cancer pain, comparable to meperidine, pentazocine, or morphine.
• Common adverse effects include mild nervous system and gastrointestinal issues (approx. 39%); it does not cause tolerance or dependence like opiates.

Conclusions:

• Ketorolac tromethamine is a potent analgesic for short-term management of moderate to severe pain.
• It offers an alternative to opioid analgesics, lacking respiratory depressant effects.
• While effective, it shares the potential toxicities common to NSAIAs.
