Abstract
The present invention utilizes ultramicropulverization and dripping pill preparation production process to make domperiodine dripping pills, and can attain the goal of raising disintegration and dissolution speed, quickly obtaining therapeutic effect, raising stability of medicine, reducing dose of auxiliary material, reducing production cost and convenient administration. Said pill not only can be sucked, but also can be swallowed, and its compliance property is good.
Description
Technical field
The present invention relates to a kind of pharmaceutical product and preparation method thereof, specifically domperidone drip pill and preparation method thereof.
Background technology
Domperidone is a periphery dopamine receptor blocade, directly act on gastrointestinal wall, can increase esophagus bottom sphincter tone, prevent stomach-esophageal reflux, strengthen gastric peristalsis, promote gastric emptying, coordinate the motion of stomach and duodenum, suppress to feel sick, vomit, and can prevent bile reflux effectively, do not influence gastric secretion.Domperidone is difficult for by blood-cerebrospinal fluid barrier, and to dopamine receptor unrestraint effect in the brain, therefore, no extrapyramidal system etc. are neural, spiritual untoward reaction.
The oral post-absorption of domperidone is rapid, but 15~30 minutes peaking blood drug level.Distribution is the highest with the gastrointestinal local drug concentration, and blood plasma takes second place, and does not almost have in the brain.Domperidone is almost all at intrahepatic metabolism, half-life (t
1/2) be 7 hours, be 31.23% by the urine excretion total amount, the original shape medicine accounts for 0.4%; Defecate total amount 65.7%, the original shape medicine accounts for 10%.
Clinical being used for: 1. alleviate by gastric emptying delays, gastrointestinal tract instead flows, esophagitis causes indigestion symptom as: epigastrium feeling of distension and oppression sense, abdominal distention, Upper abdominal pain, belch, flatulence, mouthful have or do not have the stomach burn feeling of anti-stream gastric content.
2. treat that functional, organic, infectious, diet, radiation treatment or chemotherapy are causedly felt sick, vomiting.
The domperidone tablet disintegration time is long, and dissolution and dissolution rate are low, absorption difference, bioavailability is low, and the supplementary product consumption ratio is big, and child, old people, bed patient and dysphagia patients are taken inconvenience, compliance is poor, has influenced the performance of domperidone therapeutical effect.
The present invention makes the domperidone drip pill agent by using ultramicro communication technique and dropping pill formulation Technology exactly, thereby overcomes the above defective of domperidone tablet, and the therapeutical effect of domperidone is given full play to.
Summary of the invention
The domperidone drip pill of making by using ultramicro communication technique and dropping pill formulation Technology not only have disintegrate molten loose fast, dissolution and dissolution rate improve, steady quality, the pill volume is little, both can swallow also can buccal, easy to carry and use, onset is rapid, compliance is good, be particularly suitable for the characteristics that child, old people, bed patient and dysphagia patients are taken, but also have working condition and production equipment is simple, production cost is low, compare the advantage that supplementary product consumption reduces with tablet, demonstrated fully the new drug research exploitation spirit that people-oriented.
For achieving the above object, the present invention by the following technical solutions: the domperidone fine powder of 1 weight portion through micronizing is added in 1~10 weight portion molten matrix, abundant mixing, dropping preparation method is condensed into ball in coolant, remove coolant, drying, promptly.
The molecular formula of domperidone among the present invention (Duopanlitong) is C
22H
24ClN
5O

Substrate among the present invention includes but not limited to polyethylene glycol 6000, Macrogol 4000, polyethylene glycol 1500, cetomacrogol 1000, sodium stearate, glycerin gelatine, poloxamer, stearic acid, glycerol monostearate acid, insect wax etc.
Coolant among the present invention includes but not limited to dimethicone, liquid paraffin, vegetable oil, water, alcoholic solution etc.
Below through detecting to beneficial effect of the present invention as directed
One, detects index and method
1. disintegrate (molten loosing) time limit: check according to inspection technique disintegration (two appendix XA of Chinese Pharmacopoeia version in 2000).
2. dissolution rate: sample thief, according to dissolution method (two appendix XC second methods of Chinese Pharmacopoeia version in 2000), with sodium chloride 2g, add water and make dissolving in right amount, add hydrochloric acid 7ml, thin up is to 1000ml again, shake up, getting 500ml is solvent, and rotating speed is that per minute 100 changes, operation in accordance with the law, in the time of 10,20,30,40,50 minutes, it is an amount of to get solution, filters, and filtrate is as need testing solution.It is an amount of that other gets the domperidone reference substance, adds methanol and make the solution that contains 1mg among every 1ml, and precision is measured 1ml, puts in the 50ml measuring bottle, adds above-mentioned solvent dilution to scale, shakes up, in contrast product solution.According to spectrophotography (two appendix IV of Chinese Pharmacopoeia version in 2000 A), measure trap respectively at the wavelength place of 284nm, calculate stripping quantity.
