What does ketorolac tromethamine consist of?
Ketorolac tromethamine is the salt form of ketorolac, used as the active ingredient in many formulations (for example, injection and oral products). The “tromethamine” part refers to the counter-ion that helps make the drug suitable for dosing in a specific formulation.
How is ketorolac tromethamine typically expressed on labels?
On drug labels and packaging, it is usually written as:
- Ketorolac tromethamine (the active ingredient), often followed by the strength (for example, in mg/mL for injectable products).
What’s the difference between ketorolac and ketorolac tromethamine?
Ketorolac is the pharmacologic drug moiety. Ketorolac tromethamine is the salt form used to improve formulation properties (such as solubility and how the drug can be delivered in a given dosage form). The “active” medicinal component is still ketorolac, but delivered as the tromethamine salt.
What else is in ketorolac tromethamine products besides the active ingredient?
The exact “composition” beyond ketorolac tromethamine depends on the specific product and dosage form (e.g., injection vs. tablet vs. ophthalmic product). In general, marketed drug products also include inactive ingredients (excipients) such as buffers, solvents, and preservatives appropriate for that route of administration—those excipients are product-specific.
If you tell me which ketorolac tromethamine product (strength and dosage form, such as “ketorolac tromethamine injection 30 mg/mL” or “tablets X mg”), I can help narrow down the specific inactive components reported for that formulation.
