Ketorolac or ketorolac tromethamine (marketed as Toradol - generics have been approved) is a non-steroidal anti-inflammatory drug (NSAID) in the family of propionic acids, often used as an analgesic, antipyretic (fever reducer), and anti-inflammatory. Ketorolac acts by inhibiting bodily synthesis of prostaglandins. Ketorolac in its oral and intramuscular preparations is a racemic mixture of R-(+)(which is the salt 1H-Pyrrolizine-1-carboxylic acid,5-benzoyl-2,3-dihydro- ketorolac) and S-(-) (which does not have the 1H-Pyrrolizine-1-carboxylic acid,5-benzoyl-2,3-dihydro group) ketorolac.
