Biological Activity

Description Lornoxicam (Chlortenoxicam) is a non-steroidal COX-1/COX-2 inhibitor, used as an anti-inflammatory drug to treat pain, osteoarthritis, and rheumatoid arthritis.
Targets
COX-1 [4]
(platelet)		 COX-2 [4]
(J774.2 cells)
5 nM 8 nM
In vitro
In vitro Lornoxicam is as effective as the opioid analgesics morphine, pethidine (meperidine) and tramadol in relieving postoperative pain following gynaecological or orthopaedic surgery, and as effective as other NSAIDs after oral surgery. Lornoxicam is also as effective as other NSAIDs in relieving symptoms of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute sciatica and low back pain. [1]
In Vivo
In vivo Lornoxicam dose relatedly reduces the total number of c-Fos-LI neurons with the strongest effect corresponding to the 75% reduction for the highest dose of 9 mg/kg, and the 45% reduction for the low dose of 0.3 mg/kg. Lornoxicam (0.1, 0.3 mg/kg, 1 mg/kg, 3 mg/kg and 9 mg/kg, i.v.) significantly reduces the number of c-Fos-LI neurons in both superficial (24%, 33%, 53%, 54%, and 63% reduction, respectively) and deep (28%, 48%, 62%, 69% and 79% reduction, respectively) laminae of the dorsal horn of the spinal cord. [2] Lornoxicam reduces hyperalgesia with an effective dose that provides 50% inhibition (ED50) of 0.083 mg/kg, 3.9 mg/kg and 4.3 mg/kg respectively in a chronic rat model of arthritis. Lornoxicam significantly reduces the PGE2 level in paw exudate and the cerebrospinal fluid in rats. Lornoxicam 0.16 mg/kg, celecoxib 4 mg/kg and loxoprofen 2.4 mg/kg significantly reduces hyperalgesia to a similar extent in acute oedematous rats. [3]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
