Embodiment 3

[0065] The influence of embodiment 3 on rabbit blood lipid

[0066] Take 12 healthy male Japanese long-eared rabbits, weighing 2.0-2.5Kg, and divide them into two groups at random, 6 in each group. The first group is given the fat emulsion of Example 1, and the second group is given the fat emulsion of Example 2. The administration dose is 50mg / kg, and the administration speed is 0.5mg / s.

[0067] The administration method was puncture and catheterization through the ear vein of rabbits. If there was blood back in the indwelling needle and a small amount of normal saline was injected without resistance, it indicated that the catheterization was successful. After the catheterization was successful, the puncture needle was fixed with a suture needle, and intravenous injection was performed at a constant speed. and pre-infusion (T 0 ), 1 hour after infusion (T 1 ), 3 hours (T 2 ), 6 hours (T 3 2ml of venous blood was drawn at each time point for blood lipid detection.

Abstract

The invention relates to a flurbiprofen axetil medium-chain and long-chain fat emulsion and a preparation method thereof. The fat emulsion comprises flurbiprofen axetil, long-chain oil for injection, medium-chain oil for injection, emulsifier, isotonic agent, pH regulator and water for injection, wherein the weight-volume percentage of the flurbiprofen axetil is 0.5-5%(w / v), the weight-volume percentage of the long-chain oil for injection is 5-10%(w / v), the weight-volume percentage of the medium-chain oil for injection is 5-10%(w / v), and the weight-volume percentage of the isotonic agent is 1-5%(w / v).

Description

technical field [0001] The invention relates to a medium-long-chain fat emulsion of flurbiprofen axetil and a preparation method thereof. Background technique [0002] Flurbiprofen axetil, its chemical name is: (±) 2-(2-fluoro-4-biphenyl)propanoic acid-1-acetoxyethyl ester [0003] Its structural formula is: [0004] [0005] Molecular formula: C 19 h 19 FO 4 [0006] Molecular weight: 330.36 [0007] Flurbiprofen belongs to non-steroidal anti-inflammatory drugs, the mechanism of action is mainly to inhibit the activity of cyclooxygenase in the arachidonic acid cascade cascade, thereby inhibiting the synthesis of prostaglandins that cause pain and inflammatory reactions, and play an analgesic role . Its analgesic effect is stronger than that of aspirin, and even surpasses the new analgesic. However, flurbiprofen is insoluble in water, and its sodium salt has severe pain when injected, so it cannot be administered intravenously. Flurbiprofen axetil is a prodrug pr...
