Problems solved by technology

[0007] The applicant has surprisingly found in a large number of experimental studies that by adding tromethamine to the solution of ibuprofen and arginine, not only the problem of poor water solubility of ibuprofen is solved, but also the prepared composition solution is chlorinated The stability in sodium injection or glucose injection or sodium lactate Ringer injection has been extremely significantly improved, obviously better than the ibuprofen injection that prior art provides in sodium chloride injection or glucose injection or sodium lactate ringer. Stability in Gelatin Injection

Embodiment 1

[0024] Ibuprofen 500g

[0025] Arginine 400g

[0026] Tromethamine 100g

[0027] Add water to 5L

[0028] Take 3L of water for injection, add arginine and ibuprofen, stir until dissolved, then add trometamol, stir to dissolve and mix evenly, add 0.2% (2g / L) medicinal activated carbon, stir for 30min, filter to remove drug Use carbon to cool to room temperature, then add water to 5 L, fine filter with a 0.22 μm microporous membrane, and obtain the solution of the composition of the present invention. The resulting solution had a pH of 8.3 and a concentration of 100 mg / mL.

[0029] The ibuprofen pharmaceutical composition solution is packaged in ampoules, sterilized at 121° C. for 15 minutes, packaged and then stored, and divided into 1000 bottles. In clinical use, it is diluted to the required concentration with physiological saline or glucose solution.

Embodiment 2

[0031] Ibuprofen 500g

[0032] Arginine 500g

[0033] Tromethamine 5g

[0034] Add water to 5L

[0035]Take 2.5L of water for injection, add arginine and ibuprofen, stir until dissolved, then add tromethamine, stir to dissolve and mix evenly, add 0.2% medicinal active carbon, stir for 30min, filter to remove medicinal carbon, and then Continue to add water for injection to dilute to 5 L, fine filter with a 0.22 μm microporous membrane, and obtain the composition solution of the present invention. The concentration is 100mg / mL.

[0036] Injection was prepared according to the method of Example 1.

Embodiment 3

[0038] Ibuprofen 500g

[0039] Arginine 1000g

[0040] Tromethamine 25g

[0041] Propylene glycol 100g

[0042] Dilute to 5L with water

[0043] Take 3L of water for injection, add arginine, ibuprofen, and tromethamine, stir until dissolved, then add propylene glycol, stir to mix evenly, add 0.2% (2g / L) medicinal activated carbon, stir for 30min, filter to remove Medicinal carbon, then continue to add water for injection to dilute to 5L, fine filter with a 0.22 μm microporous membrane, and obtain the composition solution of the present invention. The concentration is 100mg / mL.

[0044] Injection was prepared according to the method of Example 1.

Abstract

The invention discloses an ibuprofen medicinal composition for injection. By adding tromethamine into solution of ibuprofen and arginine, the stability of the ibuprofen medicinal composition in clinical application is improved. Experiments prove that: after being diluted by the sodium chloride injection or glucose injection or sodium lactate Ringers injection, the composition solution can be stably stored for at least 12 hours.

Description

technical field [0001] The invention discloses a pharmaceutical composition solution of ibuprofen, in particular to a pharmaceutical composition comprising ibuprofen, arginine and tromethamine, and belongs to the field of medicine. Background technique [0002] Ibuprofen is a non-steroidal anti-inflammatory and analgesic drug commonly used in clinical practice. Its chemical name is 2-(4-isobutylphenyl)propionic acid. It has significant antipyretic, analgesic and anti-inflammatory effects. It mainly treats arthritis, Relieves various types of mild and moderate pains such as colds, dysmenorrhea, etc. The currently used ibuprofen is mainly a racemate. Existing studies have confirmed that S-ibuprofen has pharmacological activity in the human body, while R-ibuprofen is basically ineffective. After R-ibuprofen enters the human body, about 60 % converted to S-ibuprofen to have pharmacological activity. S-ibuprofen is gaining popularity in the pharmaceutical field due to its bette...
