Description
Technical field
The present invention relates to a kind of plasticity mist membranization transdermal spray agent and its system using meso-porous nano silica as carrier
Preparation Method.
Background technology
At present, deposited by interaction in vitro in the conventional preparation containing medicine of human body, mainly patch, gel, emulsifiable paste
In many defects, if patch is to skin irritation caused by the closure function of skin;Medicine caused by crystallization of the medicine in patch
Quality problem;And after the administration of large area patch product, influence attractive in appearance etc..Semisolid dosage form such as gel and ointment, it is most
Major problem is that can not dosed administration exactly, easily removed because of friction, not only influence transdermal effect, and pollution clothes,
Reduce patient's compliance.
Ketoprofen, brufen etc. are conventional NSAIDs (NSAIDs).Ketoprofen has a chiral centre, and one
As Clinical practice is supplied all in the form of racemic modification, but only d-isomer just has anti-inflammatory antirheumatic and analgesic activity, left-handed
Body does not almost have pharmacological activity.Exploitation of the developed country to single enantiomer is extremely paid attention to, and most of drugmakers start to consider
Chiral drug branch is established in their drug development portion.FDA has early just issued the guidance about chiral drug in 1992
Principle, new drug research from now on develop the direction increasingly towards single enantiomer.The use of dexketoprofen advantageously reduces
The toxicity of medicine and influencing each other between nonactive enantiomer, can because his activity is 2 times of racemic modification
To supply Clinical practice using the dosage of racemic modification half, it can so mitigate the burden of liver and the formation of whole metabolin.
There is potential acylation reaction between the acyl glucose aldehydic acid metabolin and protein of other Ketoprofen, easily induce Immune Sensibility
With the selective toxicity of tissue, and d-isomer because eliminating the acyl glucose aldehydic acid of levo form so as to reducing this active generation
Thank to the quantity of product, this patient bad to those hepatic and renal functions is especially useful.
Dexketoprofen is developed by Italian Menarini companies, is listed first in Spain in 1996.So far, there is the right side
Revolve the oral formulations and injection of Ketoprofen.
Studying data at home and abroad shows that Ketoprofen has the selectivity of height to COX-1 inhibitory action.Experiment in vitro table
Bright, stronger to COX-2 inhibitory action, its IC50 is 0.024 μm of ol/L, by contrast, levo form in very high concentration (>1μ
Mol/L could produce 40% inhibitory action, it is believed that it is relevant to contain micro d-isomer with it.Observe to intact cell COX-2
Inhibitory action, it is found that suppression IC50 of the d-isomer to monocyte COX-2 is 2~25 μm of ol/L, be levo form 100~
500 times.It can therefore be concluded that going out, chiral NSAIDs has certain selectivity to COX-1 and COX-2 inhibitory action, in the past
Observed racemic modification is as caused by d-isomer to COX-2 inhibitory action.
The most common adverse reactions of NSAIDs are gastrointestinal toxicities, especially most common with the elderly and long-term prescription person.Most
Serious adverse reaction is hemorrhage of gastrointestinal tract, in addition also protein reduction, bile malabsorption etc..Toxicity research shows,
Rat 10~20mg/kg of single oral dose d-isomers do not influence on intestinal mucosa, and 20~40mg/kg racemic modification is to small intestine
There are a significantly damages with cecum mucosa, caused by this toxicity is probably the synergy between levo form and d-isomer.Medicine generation
Dynamics research shows that health volunteer's single takes 12.5mg or 25mg, can reach peak in 0.25-0.75 hours blood concentration
Value, Cmax is respectively 1.4mg/L and 3.1mg/L.Dexketoprofen is mainly with prototype medicine, hydroxylation metabolism thing and corresponding grape
The form of glycuronide metabolin is present.About 70-80% medicine is mainly latter 12 hours in clothes in the form of glucuronide conjugate
Drained from urine.
Rheumatoid arthritis is the frequently-occurring disease of serious threat human health, common disease, be using multi-joint chronic inflammation as
The autoimmune disease mainly showed, disability rate are higher.Pain is one of most common symptom of malignant tumor patient.According to generation
Boundary health organization statistics, the annual new cancer patient 7,000,000 in the whole world, wherein 30%-50% is with different degrees of pain, seriously
Influence the daily life of patient.The pain of cancer patient can be alleviated by implementing tumour analgesia therapy.It is demonstrated experimentally that KPF is a kind of slow
The active drug of solution and treatment of cancer pain, oral KPF analgesic effect is quite or better than morphine.Dexketoprofen has analgesia concurrently
And antipyretic properties, clinically it is mainly used in treating ankylosing rachitis, rheumatoid arthritis and osteoarthritis, foreign countries are also
For postoperative analgesia, dentistry pain, acute visceral pain, acute injury of muscle, chronic cancer pain and primary dysmenorrhea etc..
