Background: Intravenous regional anesthesia is a simple and reliable method for upper extremity surgery. In order to increase the quality of blocks and reduce the amount of pain, many drugs are used with lidocaine. In this study, the effect of ketorolac-lidocaine in intravenous regional anesthesia was investigated. Methods: 40 patients undergoing elective upper limb with America Society of Ane...

Possible central mechanisms underlying the analgesic action of Ketorolac, a non-steroidal antiinflammatory drug (NSAID) have been investigated using an iontophoretic approach. We found that the excitation induced by N-methyl-d-aspartate (NMDA) on spinal wide dynamic range (WDR) neurons was prevented, or reduced, by Ketorolac applied before or after the start of the NMDA ejection. The data sugge...

UNLABELLED This randomized, blind study was designed to determine the appropriate dose of ketorolac (a drug used as a supplement to opioids) to administer to patients who have undergone spinal stabilization surgery. The ketorolac was administered every 6 h, in addition to patient-controlled analgesia (PCA) with morphine, to 70 inpatients undergoing spine stabilization by one surgeon. The study ...

OBJECTIVE We determined the postoperative pharmacokinetics (PK), safety, and analgesic effects of ketorolac in 14 infants (aged <6 months) receiving a single intravenous (IV) administration of racemic ketorolac or placebo. BACKGROUND Information on the PK of ketorolac in infants is limited. Unblinded studies suggest ketorolac may be useful in infants. METHODS This double-blinded, placebo-co...

PURPOSE To evaluate the aqueous humor concentrations and cyclooxygenase (COX) inhibitory activities of nepafenac, amfenac, ketorolac, and bromfenac after topical ocular administration of Nevanac (nepafenac 0.1%), Acular LS (ketorolac 0.4%), or Xibrom (bromfenac 0.09%). SETTING Five private ophthalmology practices throughout the United States. METHODS Patients requiring cataract extraction w...

The non-steroidal anti-inflammatory drug (NSAID) ketorolac tromethamine 0.4% ophthalmic solution, a recent reformulation containing 20% less active ingredient that the original formulation, is indicated for the reduction of ocular pain and burning/stinging following corneal refractive surgery. Clinical studies have shown ketorolac tromethamine 0.4% to be as effective as ketorolac tromethamine 0...

T hank you for the opportunity to respond to the points put forth by the reader regarding the use of SPRIX ® (ketorolac tromethamine) nasal spray. As the developer of SPRIX ® , the reader points out that prior pharmacokinetic data comparing oral with intramuscular (IM) ketorolac indicate that the time for the drug to reach maximum plasma concentration (t max) is as low as 20 minutes in fasted i...

BACKGROUND Reactive oxygen species (ROS) induce lipid peroxidation and tissue damage in endothelium. We studied the influences of ketorolac and diclofenac on ROS effects using the endothelium of rabbit abdominal aorta. METHODS Isolated rabbit aortic rings were suspended in an organ bath filled with Krebs-Henseleit (K-H) solution bubbled with 5% CO(2) and 95% O(2) at 37.5℃. After being stimula...

Pain after surgery results in significant morbidity, and systemic opioids often fail to provide adequate analgesia without marked sedation and respiratory depression. Intrathecal morphine provides better analgesia, but is limited by delayed respiratory depression. Intrathecal injection of the cyclooxygenase inhibitor, ketorolac, has recently entered clinical trials, and the current study examin...

BACKGROUND Ketorolac has been used as a postoperative analgesia in combination with opioids. However, the use of ketorolac may produce serious side effects in vulnerable patients. Propacetamol is known to induce fewer side effects than ketorolac because it mainly affects the central nervous system. We compared the analgesic effects and patient satisfaction levels of each drug when combined with...
