Summary of the invention
The object of the present invention is to provide a kind of novel form that can overcome the insufficient cefadroxil of above-mentioned dosage form and preparation method thereof.
The present invention relates to a kind of cefadroxil oral cavity disintegration tablet, comprising the cefadroxil of effective dose and can be in the oral cavity rapidly disintegrate discharge the pharmaceutically acceptable excipient of medicine.
The cefadroxil oral cavity disintegration tablet contains principal agent cefadroxil, water-soluble filler, disintegrating agent, lubricant, also contains wetting agent or binding agent.
Various main materials and auxiliary materials weight shares prescription in the total amount shared ratio as follows:
A, principal agent 5~60%
B, water-soluble filler 10~70%
C, disintegrating agent 3~50%
F, lubricant 0.5~5%
E, wetting agent or binding agent 1~10%.
Water-soluble filler selects for use erythrose, mannitol, sorbitol, xylitol or other to help the material of moisture penetration in the pharmaceutical preparation, or the mixture of above two or more material.
Disintegrating agent is selected microcrystalline Cellulose (MCC), low-substituted hydroxypropyl cellulose (L-HPC), cross-linked carboxymethyl cellulose sodium (CCNa), polyvinylpolypyrrolidone (PVPP), crosslinked carboxymethylstach sodium (CCMS-Na) for use, or the mixture of above two or more material.
Can also contain gas-producing disintegrant in the above-mentioned disintegrating agent, as citric acid, tartaric acid, fumaric acid, sodium bicarbonate, sodium glycine carbonate, Glycine sodium fumarate.
Lubricant can be selected magnesium stearate, Pulvis Talci for use, or the two mixture.
The optional water of wetting agent, ethanol, or the mixture of the two.
Binding agent can be selected starch slurry, polyvidone or various cellulose family for use, or the mixture of above two or more material.
For covering the peculiar taste of cefadroxil, can also add the correctives that accounts for prescription gross weight 2~10% in the present invention, aspartame, cyclamate, saccharin sodium, Mentholum and various fruit powder essence etc. all can satisfy the requirement that improves cefadroxil oral cavity disintegration tablet mouthfeel.
This dosage form adopts wet granulation technology, can use conventional tablet pharmaceutical equipment production.
Concrete preparation method is as described below:
Take by weighing cefadroxil, water-soluble filler, correctives and part disintegrating agent by 100 mesh sieves; add an amount of wetting agent or binding agent granulation behind the mix homogeneously; with the disintegrating agent and the dried particles mix homogeneously of remainder, the qualified back of the inspection of semifinished product adds lubricant, and tabletting promptly behind the mixing.
The present invention runs in the oral cavity after the saliva rapidly that disintegrate becomes fine particle, and in order to investigate disintegrate effect of the present invention, we simulate oral environment and have formulated corresponding dissolve scattered time limit and molten shot degree algoscopy, and method is as follows:
The dissolve scattered time limit algoscopy is got this product a slice, put in the glass dish, getting the scale dropper measures 37 ℃ of water of 1ml and directly drips on unilateral, and the control rate of addition was finished timing simultaneously, inspection during to 45 seconds in 30 seconds, this product Ying Rong clears entirely, do not clear entirely as molten, get hard paper and scratch, hard core must not be arranged.
Molten shot degree algoscopy is got this product a slice, according to inspection technique disintegration (two appendix X of Chinese Pharmacopoeia version in 2000 A) lower device requirement, and hanging basket bottom screen cloth is replaced by 26 eye mesh screens, this product is put in the disintegration tester hanging basket, regulate the hanging basket height and make the bottom screen cloth concordant, and when this product contact water surface, pick up counting, in the time of 45 seconds with the water surface, mention the hanging basket inspection, should all pass through screen cloth.
According to said method the present invention and cefadroxil ordinary tablet are checked that the present invention all can moltenly loose in 45 seconds and by screen cloth, ordinary tablet is all defective, disintegration time of the present invention is significantly shorter than ordinary tablet, compares with ordinary tablet, and this dosage form has the following advantage:
The first, disintegrate is rapid, and is rapid-action.The present invention can be in 45 seconds in mouth disintegrate fast, make the rapid stripping of medicine, compare with cefadroxil conventional tablet or capsule, shortened dissolution time, accelerate its absorption, make medicine can bring into play the whole body therapeutic effect rapidly.
The second, intestinal is residual little, absorbs fully, and side effect is low.Cefadroxil has in various degree gastrointestinal reaction to some patient, as feel sick, vomiting.The present invention before reaching gastrointestinal tract rapidly disintegrate also be dispersed into trickle granule, medicine is extensively distributed in gastrointestinal tract, absorption point increases, and absorbs more fully, and has reduced medicine to the gastrointestinal local excitation.
The 3rd, medication is convenient.Cefadroxil need every day medication 2~3 times misses owing to reasons such as the inconvenience that is busy with one's work, fetches water may cause, thereby influences the antibacterial effect of medicine.The present invention needn't use water delivery service, saliva can make oral cavity disintegration tablet disintegrate or dissolving, both can resemble ordinary tablet swallows, can be placed in the water again and take after the disintegrate, also can need not to take medicine with water swallow, can take whenever and wherever possible, provide a great convenience condition, can guarantee that more medicine takes on time for the patient takes medicine.
The 4th, mouthfeel is good.Cefadroxil has a kind of special flavor of smelling, and makes us uncomfortable taste even the tablet of swallowing also can stay in mouth.The present invention has refrigerant Herba Menthae and fruit aroma and does not have obvious abnormal flavour after taste masking is handled, no sand type, and patient especially children taking compliance is good.
The generation of above-mentioned effect be because, it is described: water-soluble fillers such as erythrose and mannitol orally-dissolvable rapidly, cool taste is sweet and tasty, to thermally-stabilised, non-hygroscopic, can increase the hardness of tablet, very little to the disintegrate influence, be the desirable filler of oral cavity disintegration tablet; Microcrystalline Cellulose plays dual parts to fill and disintegrate in this test recipe, it has spongiform porous tubular structured, during pressurized, loose structure is by disorderly and unsystematic and become linear array, plastic deformation in addition, make it meet water after, hydrone enters tablet inside, destroy the hydrogen bond between the crystallite, impel disintegration of tablet; Low-substituted hydroxypropyl cellulose L-HPC has good hygroscopicity, meets water-soluble expanding and microcrystalline Cellulose when being used, and can play the disintegrate effect of the best.Citric acid contacts low amounts of water with sodium bicarbonate just can produce a large amount of bubbles, has helped the disintegrate of tablet more; Mentholum has the bad flavor of smelling that local anesthetic action can masking agents because of it, and cool taste, share as correctives to reach the flavoring effect with sweeting agents such as aspartame and essence.
