Description
Technical field:
The present invention relates to a kind of matrix core and preparation technology thereof who is used for digestive tract evacuation-detecting slow-release tablet.
Background technology:
Development along with technology such as microelectronics, integrated circuits, electronic capsule is as a kind of novel digestive tract diagnosis product, progressively entered clinical practice, as capsule endoscope, herbicide placement electronic capsule, digestive tract detected electrons capsule etc., one of common trait of these products is: the shell of electronic capsule is materials such as the medical plastic that can not degrade in digestive tract or rustless steel.In use there is serious hidden danger in these products: electronic capsule might block in digestive tract.Can not discharge gastral situation in case electronic capsule takes place,, can take out by gastroscope if electronic capsule still is arranged in stomach; If but block in intestinal, particularly be positioned at small intestine distal end, utilize the operation of small intestinal endoscope taking-up electronic capsule just very difficult, if can not take out, just can only adopt laparotomy ventrotomy, cause great injury to the patient.In clinical practice in the past, electronic capsule once repeatedly occurs and can not discharge digestive tract, must be by the case of laparotomy ventrotomy taking-up.
Before taking electronic capsule, for fear of the situation of blocking, current employing method is: (1) disease history inquire, get rid of patient with digestive tract disease history; (2) digestive tract function detects, and the barium sulfate of swallowing carries out digestive tract X line perspective and detects, if the patient exists certain digestive tract disease or dysfunction, then forbids the electronic capsule of swallowing.Clinical practice shows, even carried out disease history inquire and all-digestive tract detection, the still often generation of situation that electronic capsule blocks takes place.Therefore, for electronic capsule can more safely be used, press for the deficiency that a kind of method overcomes existing detection technique.
Clinical research shows, in order to detect the safety that the patient swallows electronic capsule, the most reliable way is once to simulate to swallow, the simulation capsule that simulation is swallowed should satisfy following requirement: (1) is in normal digestive tract evacuation time range, be generally about 24 hours, shape, the size of simulation slow releasing tablet do not change, but can be finally by disintegrate in digestive tract; (2) the simulation slow releasing tablet is stranded in the some positions in the digestive tract, can be shown under x-ray fluoroscopy equipment.
The digestive tract evacuation-detecting slow-release tablet of extremely low disintegration rate can satisfy above-mentioned requirements, matrix core is to realize the key of low speed slow-release function, the disintegration time of current matrix core design is the normal emptying time design according to human body substantially, in normal digestive tract evacuation time range,, can't satisfy the capsular requirement of simulation all by complete disintegrate.Therefore, press for a kind of new matrix core that is used for digestive tract evacuation-detecting slow-release tablet of development, realize above-mentioned requirements.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of low speed disintegrate, can be by radioscopy equipment matrix core that survey, that be used for digestive tract evacuation-detecting slow-release tablet and preparation technology thereof.
For achieving the above object, technical scheme of the present invention is as follows: a kind of matrix core that is used for digestive tract evacuation-detecting slow-release tablet, comprise following component and mass percent: indissoluble medicinal materials=30-90%, X ray developing agent=5-50%, disintegrate adjuvant=5-65%, described indissoluble medicinal materials is ethyl cellulose or cerotic acid cellulose or high viscosity hydroxypropyl cellulose or hypromellose phthalate ester or hydroxymethyl ethyl cellulose or acrylic resin; Described X ray developing agent is barium sulfate developing agent or iodide reagent; Described disintegrate adjuvant is Sodium Hydroxymethyl Stalcs or crospolyvinylpyrrolidone or low-substituted hydroxypropyl cellulose.
Be used for digestive tract evacuation-detecting slow-release tablet matrix core preparation technology in the following order step carry out:
1) prepares the matrix core material: according to the quantity of the matrix core of required preparation, according to indissoluble medicinal materials=30-90%, X ray developing agent=5-50%, disintegrate takes by weighing the matrix core material with the mass ratio of adjuvant=5-65%, is positioned in the agitator and stirs;
2) compacting matrix core: the distilled water that in the matrix core material, adds matrix core quality of materials 10-50%, mix homogeneously, utilize medicinal tablet machine and matrix core mould, be pressed into matrix core, matrix core is put into baking oven, 40-80 ℃ of oven dry, drying time is 4-12 hour, also natural drying at room temperature.
The present invention compares with art methods, has following technique effect:
1) the matrix core disintegration rate is low, and the simulation electronic capsule passes through digestive tract effectively.Because the main component of matrix core is awkward soluble materials, therefore, the disintegration rate of digestive tract evacuation-detecting slow-release tablet in human body alimentary canal is very slow, and disintegration time is far longer than general slow releasing tablet.Under the normal condition, the digestive tract evacuation time of human body is about 24 hours, the digestive tract evacuation-detecting slow-release tablet that utilizes matrix core of the present invention and make can keep original form to pass through digestive tract substantially, thereby simulates the pass through situation of identical shaped electronic capsule in digestive tract well.
2) can under X-ray, develop.When the patient in official hour, be generally 24 hours, and failed discharge digestive tract evacuation-detecting slow-release tablet complete or that part is complete, then carry out the x-ray fluoroscopy inspection, owing to mixed the X ray developing agent in the matrix core, can clearly observe the interior position of body of digestive tract evacuation-detecting slow-release tablet.If still shape is complete or complete substantially in vivo for digestive tract evacuation-detecting slow-release tablet, volunteer or the patient emptying ability for the object of equal volume is described; If digestive tract evacuation Function detection slow releasing tablet is in the some positions in the digestive tract in official hour always, illustrate that volunteer or patient may block in this position, the electronic capsule of the equal volume of swallowing has bigger risk.
