Description

Increase the herbal mixture and the preparation method of paeoniflorin bioavailability with piperine
Technical field:
The present invention relates to increase the herbal mixture and the preparation method of paeoniflorin bioavailability with piperine
Background technology:
The multiple disease of gynecological, for example dysmenorrhea, urgent chronic pelvic inflammatory disease, hysteromyoma and endometriosis etc. all exist few abdomen pain and inflammation in various degree.
Theory of Chinese medical science thinks that few abdomen pain is relevant with physiological environment with organic factor, and the dialectical qi stagnation blood stasis that mostly is is a little less than the taste element.And few abdomen be footpath of Liver Channel, gas desire row and liver not should, stroke its gas and pain is living.
Treatise on Febrile Diseases ancient prescription peony and licorice decoction is the good recipe of the few abdomen pain of treatment.Monarch drug Radix Paeoniae Alba acid receipts hardship is rushed down in the side, and the moon cold in nature is gentle, holds back ying-qi eliminating pathogen in the liver wood.In the TCM Gynecology field, the Chinese medicine compound of treatment dysmenorrhea, pelvic inflammatory disease, hysteromyoma and endometriosis all contains the Radix Paeoniae Alba basically and (sees Si Tuyi, Yang Jialin chief editor for details, gynecological's disease that calls for specialized treatment tcm clinical practice diagnosis and treatment, the People's Health Publisher, October in 2000 the 1st edition ISBN7-117-03827-6/R3828).
The effective ingredient paeoniflorin of monarch drug Radix Paeoniae has tangible spasmolytic, relaxing smooth muscle, antiinflammatory, analgesia and sedation in the modern medicine study discovery side.And ministerial drug Radix Glycyrrhizae in the side, the sweet slow gentle and contrary gas spleen reinforcing soil of property.Effective ingredient licoflavone of Radix Glycyrrhizae and glycyrrhizic acid also are smooth muscle contraction inhibitor and 17-hydroxy-11-dehydrocorticosterone sample antiinflammatory, no matter be single with or share, can both suppress uterine contraction and inflammatory exudation, two medicines have share synergism, and (king bathes chief editors such as life, Deng Wenlong, herbal pharmacology and application, second edition, People's Health Publisher, pp346-356; 248-260,1998, ISBN 7-117-03057-7/R3058).Above-mentioned traditional Chinese medical science doctor trained in Western medicine theoretical study results is the pharmacological basis of the few abdomen pain of peony and licorice decoction treatment gynecological.
Tcm theory thinks that the Radix Paeoniae consumption as monarch drug in the peony and licorice decoction compound recipe is big, be because few abdomen pain-suffered patient has a little less than the taste element more, and monarch drug is cold in nature, so poor appetite, absorption are not good.In the Chinese traditional treatment field, the traditional method that remedies certain flavor Chinese medicine gastrointestinal absorption difference is to strengthen the consumption of this flavor Chinese medicine when prescription.Therefore dosage every day of treatise on Febrile Diseases ancient prescription peony and licorice decoction is that four liang of Radix Paeoniaes add four liang in Radix Glycyrrhizae (ancient times one or two is roughly equal to the 31-32 gram), in later age and the modern Chinese medicine prescription, reuses Radix Paeoniae and reaches gram every days 150, can obtain obvious curative effects.(see for details Si Tuyi, Yang Jialin chief editor, gynecological's disease that calls for specialized treatment tcm clinical practice diagnosis and treatment, the People's Health Publisher, October in 2000 the 1st edition ISBN7-117-03827-6/R3828).Gently then obviously influence the curative effect of peony and licorice decoction with Radix Paeoniae.
Modern medicine and pharmacology discovers that the gastrointestinal of Radix Paeoniae its main effective ingredient paeoniflorin when orally using absorbs very poor.Behind the rat oral gavage 550mg/kg paeoniflorin, the accumulation excretion of fecaluria accounts for 10.6% and 1.08% of dosage respectively after 24 hours.Behind the quiet notes 55mg/kg paeoniflorin, bile accumulative total excretion accounts for 8.64% in 7 hours.After rabbit was irritated the stomach paeoniflorin, bioavailability was 7.24 ± 4.15% in vivo, and the highest blood drug level time (Tmax) is 77.4 minutes, and the highest blood drug level (Cmax) is 21.6mg/L.Behind the Canis familiaris L. intravenous injection 11.25mm/kg paeoniflorin, paeoniflorin appears at rapidly in the urine, and in preceding 20 minutes and 7 hours, the accumulation excretion is respectively 36.85%, 79.3% of dosage.The bile excretion accounts for 3.77% of intravenous injection amount in 7 hours.Experiment shows paeoniflorin the intestines and stomach absorption difference, in vivo mainly with original shape from renal excretion, excrement, bile excretion are minimum.Paeoniflorin blood drug level-time graph all meets two Room open models in Canis familiaris L. and rabbit body, and is widely distributed, eliminates piece, gastric infusion, low ((king bathes chief editors such as life, Deng Wenlong, herbal pharmacology and application to availability in the rabbit body, second edition, People's Health Publisher, pp352-353; 248-260,1998, ISBN7-117-03057-7/R3058).
At above-mentioned paeoniflorin gastrointestinal absorption difference and the low phenomenon of bioavailability, and the people's that cures the disease dialectical and plain body situation, Chinese medicine compound provided by the invention, on the basis of the elite that absorbs traditional outstanding ancient prescription peony and licorice decoction, further the research and development theory of Chinese medical science has added drugs for dispelling internal cold Fructus Piperis simply in compound recipe, with it is adjuvant drug, make the property of compound recipe be tending towards Wen Ping, be of value to the spleen stomach function regulating and receive, obviously increase the absorption of paeoniflorin.And, also can use the patient that cold elephant is arranged, increased the drug application scope of this compound recipe.
Piperic adding is found in dynamic test, has obviously increased the blood drug level and the bioavailability of paeoniflorin.Can improve document and summary of patent work of gastrointestinal absorption, increase blood drug level and the raising bioavailability of multiple medicine, vitamin etc. below with regard to piperic effective ingredient piperine, for gastrointestinal absorption and the bioavailability of using Fructus Piperis increase paeoniflorin among the present invention provides background and basis.
U.S. Pat-5,972,382 literature review was mentioned between sixth century of the first seven century to Christian era in Christian era, the medicine that a kind of " trikatu " arranged in India's traditional medicine, by three kinds of pungent plant Fructus Piperiss (Piper nigrumLinn.), long Fructus Piperis (Piper longum Linn.) and Rhizoma Zingiberis Recens (Zingiber officinale Rosc.) are prepared from, and the prescription of much curing the disease all uses " trikatu " to form as the basic ingredient compound recipe.The modern medicine and pharmacology test finds that " trikatu " can improve the bioavailability of multiple Western medicine.In animal experiment and the test of human volunteer, find that the effective ingredient that " trikatu " improves the Western medicine bioavailability is a piperine.
Long-term oral anti-hypertensive drug thing Propranolol usually can not be kept the effect that obtains when beginning to take medicine.Need escalated dose just can keep curative effect.But escalated dose causes side effect to take place.Discover that piperine can increase the bioavailability of Propranolol, the blood level of Propranolol obviously increases behind the use piperine.
Piperine can also improve the blood level and the bioavailability of multiple oral western medicine, comprise rifampicin (Zutshi, U.et al.Journal of the Association of physicians ofIndia, 1984:33,223-224), phenytoin (Bano et al., Planta Medica, 1987, pp.568-569), pentobarbital (Majumdar, A.N.et al., Indian Journal of Experimental Biology, 1990:28,486-487), theophylline (Bano et al., Eur.J.Clin.Pharmacol.1991:41,615-617) and propranolol (ibid).
Indian patent No.1232/DEL/89 discloses piperine and has been used for compound recipe western medicine tuberculosis and leprosy.The test that the Western medicine compound recipe that uses rifampicin, pyrazinamide, isoniazid and piperine to form carries out human volunteer is for most drug, and piperine can increase their relative blood drug level and blood peak concentration of drug.The raising of bioavailability helps to reduce drug dose and shortens the course of treatment.
Piperine increases the mechanism of bioavailability and does not illustrate as yet.The possible mechanism of action is as follows: 1. the non-absorption that promotes medicine specifically, for example increase gastrointestinal blood supply and blood circulation, reduce the destruction that gastric acid secretion reduces some drugs, strengthen the emulsifying content in the intestinal, the interior glutamine transpeptidase of increase intestinal mucosa epithelial cell etc. is participated in initiatively and the activity of the enzyme of passive transport, 2. suppress the activity of drug disposition biotransformation enzyme, prevent medicine inactivation and eliminating.
According to document, take in the enzyme that 20mg Fructus Piperis at least just can suppress in the body medicine biotransformation to be made the medicine inactivation everyone every day.
Fructus Piperis suppresses drug disposition biotransformation enzyme, can be to use with medicaments compound, and also can be before medication or after the medication, to use.This point obtains proof in the test of using theophylline and phenytoin.Using these two kinds of medicines to give Fructus Piperis 20mg in preceding 7 days, the blood drug level of these two kinds of medicines is being improved, and obviously prolonged the time that medicine is detained in blood.Possible mechanism is that Fructus Piperis has suppressed drug disposition biotransformation enzyme.In fact, this is to improving the unique reasonable explanation of bioavailability, because Fructus Piperis separates use with medicine, can not influencing the rapid absorption of gastrointestinal tract to medicine.
Another observed phenomenon is even piperic use amount is lower than the lowest dose level that suppresses biotransformation enzyme in the body, also can increases medicine and absorb rapidly at gastrointestinal.Only need 3mg Fructus Piperis and Propranolol compound recipe, just can make the blood drug level of Propranolol increase by 2 times, but can not prolong the clearance rate of this medicine.Therefore, can think that low dose of Fructus Piperis does not suppress the clearance rate of medicine biotransformation or medicine, only increases medicine and absorbs from gastrointestinal.
60 healthy premenopausal volunteers are arranged, be divided into test group and matched group.Test group is oral Fructus Piperis 20mg/ day earlier, totally 7 days, gives theophylline 150mg or phenytoin 300mg then.The maximum plasma concentration of theophylline exceeds 1.5 times in test group than matched group, and the elimination factor of theophylline obviously slows down in test group.Phenytoin at blood drug level and blood peak concentration of drug in test group than the obvious increase of matched group.And the elimination factor of phenytoin obviously slows down in test group.
U.S. Pat-5,972,382 disclose piperine and Rhizoma Curcumae Longae, Semen Ginkgo, aconitine, vitamin B1, vitamin B2, nicotiamide, vitamin B6, vitamin B12, folic acid, vitamin C, vitamin A, vitamin D, vitamin E, vitamin K, α carotene, lycopene, several amino acids comprises lysine, leucine, isoleucine, threonine, valine, tryptophan, the phenylalanine methionine, L-Selenomethionine and mineral comprise calcium, ferrum, zinc, vanadium, selenium, chromium, iodine, potassium, magnesium, method and result of the test that compound recipe such as copper and manganese uses.The compound recipe of Fructus Piperis and above-mentioned substance has improved them and has absorbed at gastrointestinal, has increased blood drug level, has improved the bioavailability of these nutritional labelings.
In sum, said medicine and piperine use together, can improve curative effect, mainly are that blood drug level increases because said medicine absorbs at gastrointestinal to be increased, and the half-life prolongs, and bioavailability improves.The medicine big to toxicity increases curative effect when can reduce dosage.Therefore, Fructus Piperis is a kind of drugs for dispelling internal cold and bioavailability reinforcing agent.
Summary of the invention:
Poor and piperine can improve gastrointestinal absorption, blood drug level and the bioavailability of multiple Western medicine, vitamin and mineral in view of the gastrointestinal absorption of above-mentioned paeoniflorin.The purpose of this invention is to provide a kind of herbal mixture that can increase the paeoniflorin bioavailability and preparation method thereof.The herbal mixture that this increases the paeoniflorin bioavailability is characterized in that, contains paeoniflorin and piperine in the herbal mixture.Piperine can improve the gastrointestinal absorption of paeoniflorin, makes paeoniflorin concentration increase in the blood, thereby reaches the purpose that improves the paeoniflorin bioavailability.
