Description

A kind of tandospirone enteric coated micropill and its production and use
Technical field
The present invention relates to a kind of tandospirone enteric coated micropill and its production and use, belong to drug world.
Background technology
Tandospirone is a kind of novel anxiolytic succeeded in developing by SUMITOMO CHEMICAL Pharmaceutical Co., Ltd, and It was approved to list first in Japan in 1996, initially enter Chinese market within 2004, anxiety at home The application of therapy field is increasingly extensive.
Tandospirone can selectively acting in intracerebral 5-ht1a receptor, site of action concentrates in emotion The cerebral limbic systems such as the Hippocampus of pivot, corpus amygdaloideum are simultaneously projected to the rapheal nuclei that 5-ht can be neural, by swashing Presynaptic 5-ht1a receptor alive, inhibitory neuron discharges, and reduces the synthesis of 5-ht, simultaneously to synapse 5-ht1a receptor afterwards has partial agonist effect, thus reaching the 5-ht function of comprehensive adjustment synapse, Play angst resistance effect.Life-time service can also play antidepressant effect simultaneously.With traditional sedative hypnotic Compare, its angst resistance effect is special, and side effect is less, and sedative-hypnotic effect is weak, no myorelaxant effects, No according to lazyness and drug withdrawal withdrawal symptom, no accumulate in vivo after prolonged application.Test through long-term clinical application Card, tandospirone has good result to the anxiety under multiple situations, with the body as feature with anxiety Heart comorbidity therapy field has a extensive future.
Tandospirone belongs to and acts on central nervous system's class medicine, and oral formulations need to first pass through gastrointestinal tract It is absorbed into body circulation, then big intracerebral action target spot competence exertion anxiety is distributed to by blood brain barrier Or antidepressant effect.Blood brain barrier is one layer of defensive barrier of brain, and the transmission of material is had strictly Restriction effect, active constituents of medicine will enter intracerebral by this layer of barrier, in addition to the permeability of itself, Also restricted by blood drug level.Clinical data is had to show, health adult is once administered orally tandospirone After 20mg, in blood plasma, maximum concentration is only 2.9~3.2ng/ml.According to the medication guide principle of tandospirone, The dosage of generally adult's application Tandospirone Citrate Tablets is that each 10mg is administered orally, and 3 times a day, and often Daily dose is limited in and must not exceed 60mg.The Film coated tablets sold in the market and two kinds of conventional capsule Oral formulations are all disintegration time length, the slow conventional formulation of dissolution after disintegrate, have impact on the absorption of medicine, So it is difficult to improve the blood drug level after being administered orally.If simple to overcome blood drug level to increase medication dose Low problem, can bring the risk that untoward reaction increases again.
According to pharmacokinetics general knowledge, weak acidic drug free state in sour environment increases, and has Preferably cell-membrane permeable, therefore weak acidic drug are easier to absorb in gastric acid environment.Citric acid Tandospirone shows faintly acid, is easier to absorb in stomach, and therefore existing tandospirone listing preparation is equal For stomach dissolution type preparation, for example: Tandospirone Citrate stomach dissolution type conventional capsule, tandospirone slow releasing tablet (cn200610021419.0), tandospirone slow-releasing granules (jp2002020291), tandospirone infiltration The slow controlled release oral dosage formulations such as pump-type controlled release tablet (us5185158, us5330762, us5858407).On State stomach dissolution type preparation and have ignored a critically important problem: tandospirone is that one kind has irritating chemical combination Thing, after gastric melts, local dose is very big, and gastric mucosa can be produced stimulates;Separately have document report is Reach long-time release effect (generally daily only need to take medicine once or twice), their content of dispersion is than general Port formulation is high 1.5~3 times, if gastric occur prominent release that to will also result in local dose excessive, from And gastric mucosa is produced and stimulates.
From the point of view of the untoward reaction evidence reported when existing tandospirone preparation Clinical practice, incidence rate is relatively The untoward reaction for digestive system aspect of high (incidence rate >=1%), comprising: Nausea and vomiting, appetite Depressed, thirsty, abdominal discomfort sense, stomachache, flatulence, abdominal distention, diarrhoea etc., this is for by digestive system Disease causes the patient of patient, mucosal lesion or easy bleeding of anxiety, needs the gerontal patient of Long-term taking medicine Particularly disadvantageous.These patients are not only low to pungent toleration, and easily induction digestive system is bad anti- Should, lead to Compliance low, and due to digestive tract function imbalance, drug absorption is poor, and medicine is biological Availability is not high, can have a strong impact on therapeutic effect.
Techniques disclosed above all has and discharges medicine in a large number in stomach, and with or may be with local dose Excessive feature, stimulates to digestive tract after failing to solve the problems, such as medication.So far, can improve by Digestive system disease causes the patient of patient, mucosal lesion or easy bleeding of anxiety, needs Long-term taking medicine The Compliance problem of gerontal patient and therapeutic effect, and it is capable of the tandospirone intestinal of efficient absorption utilization Solubility preparation has not yet to see report.
Therefore, the existing issue for tandospirone and its conventional formulation and particular patients ' demand it would be highly desirable to Develop a kind of suitable digestive system disease cause anxiety the patient of patient, mucosal lesion or easy bleeding, The tandospirone enteric coated preparation needing the gerontal patient of Long-term taking medicine to take and being fully absorbed.
