Ketorolac Trometamol Info

What is Ketorolac Trometamol?

Ketorolac trometamol is a non-steroidal anti-inflammatory drug (NSAID) that helps reduce pain and swelling. It belongs to the arylacetic acid class of NSAIDs. In Hong Kong, this active ingredient is found in several prescription and over-the-counter products such as Acular, Toradol and the generic ketorolac tablets.

Medications with Ketorolac Trometamol

• Acular - an ophthalmic eye-drop solution used for short-term relief of eye inflammation after surgery or injury.
• Toradol - available as an injection for hospital use and as oral tablets for brief treatment of moderate pain.
• Ketorolac - generic tablets supplied by various manufacturers, often prescribed for postoperative or dental pain.

These products come in different forms: sterile eye drops (typically 0.5 mg/mL), injectable solutions (usually 15 mg/mL), and tablets ranging from 10 mg to 30 mg. Both brand-name and generic versions are authorised by the Hong Kong Department of Health under the Medicines and Poisons Ordinance.

What Does Ketorolac Trometamol Treat?

• Eye inflammation - after cataract surgery, laser procedures or traumatic injury, the eye can become red and painful; the anti-inflammatory action of ketorolac helps soothe these symptoms.
• Moderate acute pain - conditions such as postoperative pain, dental extraction pain or musculoskeletal injury may be managed with a short course of ketorolac tablets or injection.
• Pain after minor surgical procedures - the drug is often given as a single injection to control pain during the first 24 hours after surgery.
• Inflammatory eye conditions - allergic conjunctivitis or other short-term inflammatory eye disorders may benefit from the eye-drop formulation.

Ketorolac is generally intended for short-term use, typically not exceeding five days for oral or injectable forms, because prolonged exposure can increase the risk of side effects.

How Ketorolac Trometamol Works

Ketorolac blocks the production of prostaglandins, chemicals in the body that cause pain, fever and swelling. By limiting prostaglandin formation, the drug reduces the sensations of pain and the visible signs of inflammation. Relief can be felt within an hour after a dose, with the strongest effect occurring during the first few hours.

Safety Information

Common Side Effects

• Mild eye irritation or temporary blurred vision with eye drops.
• Stomach upset, nausea or indigestion after oral tablets.
• Slight headache or dizziness, especially after the injectable form.

These effects are usually short-lived and resolve without medical intervention.

Serious Reactions

• Severe allergic responses such as rash, swelling of the face or throat, or difficulty breathing.
• Signs of bleeding, such as unusual bruising, blood in urine, or black stools.
• Sudden, severe stomach pain that may indicate an ulcer.

If any of these occur, seek emergency medical help right away.

Who Should Be Cautious

• People with a known allergy to ketorolac, other NSAIDs, or aspirin.
• Individuals with a history of stomach ulcers, bleeding disorders, or severe kidney disease.
• Pregnant women, especially in the later stages, should avoid ketorolac unless specifically directed by a specialist.

Interaction Awareness

• Taking other NSAIDs, blood-thinners (e.g., warfarin), or certain antidepressants can raise the risk of bleeding.
• Alcohol may increase stomach irritation; limiting intake while using ketorolac is advisable.
• Certain foods high in salt or caffeine can affect kidney function, which may be relevant for prolonged use.
