Ld 50 of ibuprofen?

What is the LD50 of ibuprofen?

The LD50 (median lethal dose) of ibuprofen depends on the species (and whether it’s measured by oral vs. other routes). Without the specific animal model and dosing route, a single numeric LD50 value can’t be stated accurately.

What numbers are usually reported for ibuprofen LD50?

Typical toxicology references list different LD50 values for different species (for example, rodents) and dosing routes (most commonly oral). To give the correct number, I would need at least:
- species (e.g., rat or mouse)
- route (oral, dermal, etc.)
- units (mg/kg)

Can you share the species/route you need?

If you tell me the species and route (for example, “oral LD50 in rats”), I can provide the matching LD50 value in mg/kg.
