Codeine Ibuprofen Arginine Compound Preparation
(1) technical field
The present invention relates to contain the compound preparation of acceptable salt composite on ibuprofen arginine and codeine or its medicine.
(2) background technology
Codeine or its pharmaceutically acceptable salt (for example codeine phosphate) are taken as the coughing centre that can directly suppress brain by those skilled in the art, have stronger antitussive effect.That also known ibuprofen (a kind of NSAID (non-steroidal anti-inflammatory drug)) has is analgesic, antiinflammatory, analgesic activity.So, not only contain ibuprofen but also contained codeine or the Orally administered composition of its pharmaceutically acceptable salt is applicable to violent dry cough and the irritable cough that a variety of causes causes, be applicable to violent dry cough especially with chest pain.Its analgesic activity can be used for moderate pain, as postoperative pain and the pain relieving of moderate cancer pain etc.
But the ibuprofen in the said composition is because water-soluble hardly, pharmacokinetic parameters T
Max(reaching the time of maximum plasma concentration) value is 1.5-2h, and the same with other oral NSAID (NSAID (non-steroidal anti-inflammatory drug)), onset is slower relatively, and gastrointestinal tract is had certain stimulation.And the codeine onset is very fast relatively, and its pharmaceutically acceptable salt (as codeine phosphate) is after oral, and general onset time was at 30~45 minutes.Be absorbed in 1 hour and peak.How to make each prescription in the drug regimen bring into play its effect simultaneously, as early as possible, becoming such medicine mainly needs the technological difficulties that solve.
(3) summary of the invention
The present invention promptly is in order to provide a kind of rapid-action, efficacy stability easily promptly to be contained the compound preparation that ibuprofen contains codeine or its pharmaceutically acceptable salt again by what patient accepted, and this compound preparation is the compound preparation of ibuprofen arginine and codeine or its pharmaceutically acceptable salt.
The present invention reaches the technical scheme that goal of the invention adopts to be:
It is 1~80: 1 ibuprofen arginine and codeine or the pharmaceutically acceptable salt of described codeine that a kind of Codeine Ibuprofen Arginine Compound Preparation, described preparation contain mass ratio.Ibuprofen has improved the water solublity of ibuprofen because of arginic combination, and absorption rate increases in the body on the one hand, and also having reduced on the other hand stimulates gastrointestinal.
Further, described preparation is 1~80: 1 ibuprofen arginine and codeine or its pharmaceutically acceptable salt by mass ratio, and pharmaceutical excipient or carrier are formed.
The pharmaceutically acceptable salt mass ratio preferred 5~50: 1 of described ibuprofen arginine and codeine or codeine, more preferably 20~40: 1.
The front pharmaceutically acceptable salt of said codeine is preferably used codeine phosphate, promptly is ibuprofen arginine and codeine phosphate.

The result shows, this product is quickened to investigate six months, every index and relatively having no significant change in 0 month.Can be obtained by above test, ibuprofen arginine codeine tablet stability is good.
Embodiment 6: the antiinflammatory test
Get body weight 140~160g rat, male and female half and half, random packet, 8 every group.Negative control group (normal saline 25ml/kg), positive controls (ibuprofen codeine 34.5mg/kg, wherein contain ibuprofen 32.7mg, codeine contains 1.8mg), embodiment 1 is prepared into the ibuprofen arginine codeine respectively by low dose group (5.4mg/kg), middle dosage group (54mg/kg), high dose group (270mg/kg).By the above-mentioned dosage gastric infusion (ig) of respectively organizing, behind the 1h, the sterile working, injection causes scorching thing (1% carrageenin 0.1ml) under every sufficient plantar aponeurosis in a rat left side.Cause scorching back 1h, 3h measures left and right sides ankle joint girth with special moccasin chi.With the difference of left and right sides ankle joint girth as the swelling degree, contrast between organizing, the poor opposite sex).The results are shown in Table 4.
Table 4. ibuprofen arginine codeine on Carrageenan causes scorching antiinflammatory action
Group | Dosage (mg/kg) | Number of animals (only) | Swelling degree (mm) r ± s | The P value |
Cause scorching back 1h | Cause scorching back 3h | Compare with saline | Compare with the ibuprofen codeine |
Normal saline | | 8 | 6.00±1.25 | 6.81±0.90 | | |
The ibuprofen codeine | 34.5 | 8 | 2.75±0.65 | 2.72±0.92 | <0.01 | |
The ibuprofen arginine codeine | 5.4 | 8 | 3.18±1.16 | 2.50±0.59 | <0.01 | >0.05 |
54 | 8 | 1.50±1.20 | 2.52±0.62 | <0.01 | >0.05 |
270 | 8 | 1.23±0.82 | 1.20±0.67 | <0.01 | <0.05 |
By last table result as can be seen: during high dose group, effect obviously is better than the ibuprofen codeine to the antiinflammatory action of ibuprofen arginine codeine about 1h and in giving.
Embodiment 7: the analgesic test
Get 60 of body weight 17~22g mices, male and female half and half, random packet, 12 every group.If the group situation reaches and respectively organizes gastric infusion dosage with embodiment 6.Ip0.6% acetic acid behind the 30min (0.2ml/ only) causes pain, raises to causing indicator reaction bitterly with mouse writhing (abdominal part caves in, trunk uphold with hind leg) buttocks.Turn round the body number of times behind the self-supporting acetic acid of observed and recorded in the 15min.The results are shown in Table 5.
Table 5. ibuprofen arginine codeine is to the analgesic activity of mice
Group | Dosage (mg/kg) | Number of animals (only) | Swelling degree (g) x ± S | The P value |
Compare with saline | Compare with the ibuprofen codeine |
Normal saline | | 12 | 20.60±5.23 | | |
The ibuprofen codeine | 34.5 | 12 | 5.76±1.52 | <0.05 | |
The ibuprofen arginine codeine | 5.4 | 12 | 6.23±2.30 | <0.01 | >0.05 |
54 | 12 | 5.12±2.19 | <0.01 | >0.05 |
270 | 12 | 2.85±0.47 | <0.01 | <0.05 |
By last table result as can be seen: ibuprofen arginine codeine compound tablet is when middle dosage, and its analgesic activity is suitable with the ibuprofen codeine, and when giving high dose, analgesic activity obviously is better than the ibuprofen codeine.
Embodiment 8: separate heat test
Get 40 of body weight 1.6~2.0kg rabbit, male and female half and half, random packet, 8 every group.The ibuprofen arginine codeine tablet of negative control group (normal saline 1ml/kg), positive controls (ibuprofen codeine 17.5mg/kg), embodiment 1 preparation is by low dose group (3.5mg/kg), middle dosage group (16.8mg/kg), high dose group (78.5mg/kg).After measuring the rabbit normal body temperature, injection colibacillus deactivating liquid (about 1012/kg antibacterial, reduced turbidity calculates) pyrogenicity.Take temperature is as the fever index behind 3~4h.Reduce number as separating heating index with each time point body temperature behind the gastric infusion.Compare with the body temperature before the back administration that heats up, the results are shown in Table 6.
Table 6 ibuprofen arginine codeine is to the influence of rabbit body temperature
Group | Dosage (mg/kg) | Give behind the bacterium before the administration elevated temperature ℃ | Different time body temperature reduction value after the administration (℃) x ± S |
60min | 90min | 120min | 150min |
Normal saline | | 1.53±0.13 | 0.11±0.10 | 0.15±0.10 | 0.075±0.10 | 0.35±0.20 |
The ibuprofen codeine | 17.5 | 1.23±0.07 | 0.13±0.10 | 0.61±0.10 | 0.92±0.10 | 1.03±0.20 |
The ibuprofen arginine codeine | 3.5 | 1.55±0.18 | 0.26±0.10 | 0.47±0.20 | 0.80±0.20 | 0.89±0.20 |
16.8 | 1.29±0.08 | 0.72±0.10 | 0.84±0.20 | 0.99±0.10 | 1.09±0.20 |
78.5 | 1.69±0.14 | 0.92±0.10 | 1.08±0.20 | 1.25±0.29 | 1.39±0.10 |
By last table result as can be seen: in giving ibuprofen arginine codeine compound tablet during dosage, its for the body-temp. reducing effect of rabbit obviously faster than the ibuprofen codeine.But the body-temp. reducing effect basically identical after two hours.
