Background technology
Dysmenorrhea is meant menstrual cycle with spasmodic colic, is divided into two kinds of constitutional and Secondary cases.Primary dysmenorrhea is meant that the genitals does not have the dysmenorrhea of organic disease; Secondary dysmenorrhea is then many to be had due to the organic disease because of the genitals.
Show that according to sampling survey primary dysmenorrhea is sent out the adolescence women in 6 months to 2 years after 15~25 years old and menophania well, about 50%~90%, 37%~55% the patient of its sickness rate influences life, study and activity.
Pointed out 80% dysmenorrhea that has in various degree among the global women according to Britain one tame authorities,medical mechanism investigation report in 2004;
The reports such as Patel V of Britain in 2006,2262 18~45 years old women of investigation India fruit Ah suffer from the dysmenorrhea number and surpass half, and 37% women arrives the severe pain warp in being.Osmanli Cakir M in 2007 etc. investigate the schoolgirl of colleges and universities, and report primary dysmenorrhea sickness rate is 89.5%.Introduce in " female chronic pelvic pain " book, the Britain women of child-bearing age 12% have serious dysmenorrhea, and 45% has moderate to the severe pain warp.It is reported that the U.S. has among the women of periodically menstruation 90% dysmenorrhea is arranged, 36% has dysmenorrhea always or often.
Dysmenorrhea is periodical attack and vicious cycle, tend to cause patient's psychasthenia, make the patient suffering hard to bear, prolonged and repeated outbreak also can influence mental health, the not normal of psychological behavior appears, such as agitation, irritability, depression, absent-minded, severe patient even crime and impulsive behavior can occur.
Hence one can see that, and dysmenorrhea is a disease comparatively general in women's illness, and harm is serious.
Western medicine thinks, the generation of primary dysmenorrhea and genitals's local patholoic change and endocrine, nervous and mental factors are relevant, mainly is owing to strength of uterine contraction strengthens, uterine blood flow reduces and the influence of pituitary hormone, the effect of neurotransmitter cause.Doctor trained in Western medicine adopts spasmolytic, analgesic and PGSI for TREATMENT OF DYSMENORRHOEA more, the short-term good analgesic effect, but can not solve root problem, and of short duration, the easy recurrence of curative effect, side effect is bigger, makes clinical practice be subjected to certain limitation.
Relieving spasm to stop pain class medicine usually before menstrual onset 12~24 hours oral, mainly comprise salicylic acid, hormones, anti-steroid anti-inflammatory type etc., this class medicine is the pain symptom of relieving dysmenorrhea effectively, can not fundamentally eliminate the cause of disease of dysmenorrhea, but its corresponding side reaction is unsuitable for patient's prolonged application as nauseating, vomiting, anaphylaxis, blood coagulation disorders, stomachache, menoxenia etc.If calm class drug main is at the patient of serious dysmenorrhea companion psychentonia, emotional instability, it represents medicine is chlorpromazine, and that the side effect that it is followed is mainly is drowsiness, tachycardia, xerostomia and constipation, postural hypotension etc., and prolonged application can cause breast swelling, amenorrhea and decreased growth etc.Endocrine therapy, generally select diethylstilbestrol, norethindrone, Norethisterone Compound sheet etc. for use, this class medicine is at the clinical recovery normal menstrual cycle that is mainly used in, therapeutic effect for primary dysmenorrhea is not good, relapse rate after the treatment is very high, because of its side reaction shows as nauseating, vomiting, anorexia, headache, dizziness, irregular colporrhagia, metrauxe, frequent micturition or painful urination etc. should not be taken for a long time.The main medicine of prostaglandin antagonist has ibuprofen (ibuprofen), naproxen (naproxan), mefenamic acid (mefenamic acid), it mainly is purpose with the pain relieving, though pain relieving is rapid, but prolonged application can develop immunity to drugs, addiction, gastrointestinal ulceration, hepatic and renal function injure, reach serious adverse reactions such as central nervous system disorder, and relapse rate is higher.
Theory of Chinese medical science thinks that the pathogenic factor of dysmenorrhea is a lot, but its pathogenesis is nothing more than " stagnation of QI and blood may bring about pain " or " not Rong Ze pain ".Tradition traditional Chinese medical herbal treatment dysmenorrhea is with a long history, determined curative effect, many Chinese medicines no matter be single or compound preparation all to improve through preceding or menstrual period few abdomen pain, distending pain of the breast, dysmenorrhea symptom such as do not relax uncomfortable in chest have remarkable effect, and curative effect is lasting, does not recur after the drug withdrawal.Thereby be subjected to the great kindness of extensive patients deeply.Development along with transition of age and society, the pathogenic factors of dysmenorrhea and the performance of clinical disease have had certain change, wherein in the majority with the patient of qi stagnation and blood stasis type primary dysmenorrhea, yet, also few through the tcm product of its determined curative effect of standardization clinical verification at present, and control from cold coagulation legislation opinion mostly, cause kind that dysmenorrhea takes place seldom, can't satisfy patient's actual demand at the stagnation of QI, the stagnation of QI.Main herbal species has TIANQI TONGJING JIAONANG, YUANHU ZHITONG PIAN, norlutin, TONGJINGBAO KELI, dysmenorrhea spirit granule and HUAHONG PIAN on the market.TIANQI TONGJING JIAONANG is primarily aimed in the cold-condensing type dysmenorrhea, uses the hot class medicine that looses of a large amount of fragrance, easily consumes gas; YUANHU ZHITONG PIAN is mainly used in stomachache, hypochondriac pain, headache and the menstrual pain of caused by energy stagnation and blood stasis, lacks specific aim, can cause feeling sick, dizzy, weak, excessively performances such as respiration inhibition, parkinson occur.Norlutin mainly is applicable to the menoxenia and the dysmenorrhea of deficiency of both QI and blood.TONGJINGBAO KELI is directed to menorrhalgia of cold and qi stagnation type, adopts a large amount of removing blood stasis medicines in the side, easily causes patient's blood deficiency symptom in treatment.Dysmenorrhea spirit granule is primarily aimed in the caused by energy stagnation and blood stasis dysmenorrhea, but square taste of Chinese medicine is various, and dose is big.HUAHONG PIAN mainly is applicable to secondary row dysmenorrhea, can not satisfy primary dysmenorrhea patient's demand.
The characteristics research and development that the present invention is based on qi stagnation and blood stasis type constitutional pain high incidence and shortage specific aim medicine form.
The present invention has determined curative effect, and effect is rapid, and clinical producing effects well used the low characteristics of no addiction and relapse rate for a long time, repeatedly.
