Description

A kind of Levofloxacin Hydrochloride Capsules and preparation method thereof
Technical field
The present invention relates to a kind of capsule and preparation method thereof more particularly to a kind of Levofloxacin Hydrochloride Capsules and its preparations Method.
Background technology
Lavo-ofloxacin hydrochloride is the levo form of Ofloxacin, and antibacterial activity is about twice of Ofloxacin, its master Mechanism of action is wanted to inhibit bacteria DNA gyrases(Bacterial topoisomerase II)Activity, hinder bacterium DNA replication.Antimicrobial spectrum Extensively, the characteristics of antibacterial action is strong.To most of enterobacteriaceae lactobacteriaceaes, such as escherichia coli, Klebsiella, Serratia, change Shape Bacillus, Shigella, Salmonella, citrobacter, acinetobacter and pseudomonas aeruginosa, the bloodthirsty bar of influenza The gram-negative bacterias such as bacterium, gonococcus have stronger antibacterial activity.To part methicillin-sensitivity staphylococcus, pneumonia streptococcus The gram positive bacterias such as bacterium, micrococcus scarlatinae, hemolytic streptococcus and Legionella, mycoplasma, Chlamydia also have good antibacterial Effect, but it is poor to anaerobic bacteria and enterococcal effect.
Suitable for caused by sensitive bacteria:1. urogenital infections, including pure, complexity urinary tract infections, bacterium Property prostatitis, NEISSERIA GONORRHOEAE urethritis or cervicitis(Including person caused by producing enzyme strain);2. respiratory tract infection is removed from office including sensitivity Bronchial infection acute attack and pulmonary infection caused by blue negative bacillus;3. alimentary infection, by Shigella, Salmonella, Caused by enterotoxigenic escherichia coli, aeromonas hydrophila, vibrio parahaemolytious etc.;4. typhoid fever;5. bone and the infection of joint;6. skin is soft Tissue infection;7. the general infections such as septicemia.
Lavo-ofloxacin hydrochloride have many uses it is general, Principle of Pain unbearably in the case of, it is better that drug effect plays a role sooner, This just needs the substance in Levofloxacin Hydrochloride Capsules that can quickly dissolve out, and then drug is made to play a role, but at present Because the selection of disintegrant and lubricant is improper, the dissolution rate for making drug is less desirable.
Invention content
The object of the present invention is to provide a kind of Levofloxacin Hydrochloride Capsules and preparation method thereof, solve hydrochloric acid levofloxacin Star pharmaceutical capsules dissolution rate is undesirable, and then prevents the problem of drug effect is from fast onset.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention provides a kind of Levofloxacin Hydrochloride Capsules, and the component and part of the capsule includes:Hydrochloric acid levofloxacin 25-88 parts of star, 26-48 parts of starch, 10-20 parts of dextrin, 4-8 parts of lactose, 6-12 parts of low-substituted hydroxypropyl cellulose, polyethylene glycol 3- 4 parts, 1-2 parts of surfactant, 1-2 parts of crospovidone, 2-4 parts of magnesium stearate, 4-5 parts of talcum powder, 1-2 parts of high melting-point wax.
Preferably, the component and part of the capsule includes:25 parts of lavo-ofloxacin hydrochloride, 26 parts of starch, dextrin 10 Part, 4 parts of lactose, 6 parts of low-substituted hydroxypropyl cellulose, 3 parts of polyethylene glycol, 1 part of surfactant, 1 part of crospovidone, stearic acid 2 parts of magnesium, 4 parts of talcum powder, 1 part of high melting-point wax.
Preferably, the component and part of the capsule includes:88 parts of lavo-ofloxacin hydrochloride, 48 parts of starch, dextrin 20 Part, 8 parts of lactose, 12 parts of low-substituted hydroxypropyl cellulose, 4 parts of polyethylene glycol, 2 parts of surfactant, 2 parts of crospovidone, tristearin Sour 4 parts of magnesium, 5 parts of talcum powder, 2 parts of high melting-point wax.
Preferably, the component and part of the capsule includes:56.5 parts of lavo-ofloxacin hydrochloride, 37 parts of starch, dextrin 15 parts, 6 parts of lactose, 9 parts of low-substituted hydroxypropyl cellulose, 3.5 parts of polyethylene glycol, 1.5 parts of surfactant, crospovidone 1.5 Part, 3 parts of magnesium stearate, 4.5 parts of talcum powder, 1.5 parts of high melting-point wax.
Preferably, surfactant is polyoxyethylene sorbitan monoleate and/or lauryl sodium sulfate.
The present invention also provides a kind of preparation methods of Levofloxacin Hydrochloride Capsules, specifically include following steps:
1)By starch, dextrin, lactose, low-substituted hydroxypropyl cellulose, polyethylene glycol, surfactant, crospovidone, tristearin Sour magnesium, talcum powder and high melting-point wax sieving, and be sufficiently mixed, mixed material is obtained, mixed material is then crossed into 80 mesh Sieve;
2) lavo-ofloxacin hydrochloride crushed 90 mesh sieve by;
3) is by step 1)In obtained mixed material and step 2)It is carried out after the lavo-ofloxacin hydrochloride drying obtained after middle sieving It is sufficiently mixed;
4) lavo-ofloxacin hydrochloride material obtained in step 3) is filled capsule by by tire bagger, you can obtains product.
The present invention uses low-substituted hydroxypropyl cellulose, surfactant and crospovidone as disintegrant, general hydrophobic Property or insoluble drugs to olighydria affinity, be not easy to be penetrated by water in hole, then can when adding in proper amount of surfactant It is preferable to solve;Crospovidone is white powder, good fluidity, due to its high molecular weight and cross-linked structure, so insoluble Yu Shui, but have it is extremely strong draw moist, water absorption can exceed that the 50% of itself weight, but remain to keep complete and do not dissolve, heap Density is smaller(0.26g/ml), therefore powder has larger specific surface area, is uniformly dispersed in capsule as disintegrant, in addition strong Capillarity, promote network structure be disintegrated and generate calving disaggregation, effect is better than starch disintegrant;Low-substituted hydroxypropyl is fine Tie up element be a kind of multiduty nonionic cellulose derivative, be mainly used as solid pharmaceutical preparation disintegration and adhesive, due to it Powder has larger surface area and a porosity, thus can quick water swelling, while between its coarse structure and drug and particle Have it is larger inlay, capsule endoparticle hardness can be significantly improved, while do not influence to be disintegrated, so as to accelerate the dissolution rate of drug, carried High bioavilability;As lubricant, talcum powder is white to pale white crystals powder for magnesium stearate, talcum powder and high melting-point wax End, good with white person, density is big, Adhesion Resistance and helps good fluidity, but adhesion and lubricity are poor, high melting-point wax typical concentrations It is 3%~5%, lubricity is fine, and Adhesion Resistance is bad, helpless fluidity, and talcum powder and high melting-point wax can be fine as lubricant Complementation, magnesium stearate is hydrophobe, and dosage, which crosses multipotency, to be influenced the disintegration time of tablet or generate sliver, using this hydrophobicity During lubricant, can add in proper amount of surfactant such as lauryl sodium sulfate simultaneously can overcome.
Beneficial effects of the present invention:The present invention selects low-substituted hydroxypropyl cellulose, surfactant and crospovidone to make For disintegrant, as lubricant, the complementary synergistic effect between them can make glue for magnesium stearate, talcum powder and high melting-point wax Intracapsular particle fater disintegration, makes drug-eluting, and drug effect is brought into play rapidly, shortens the pain time of patient, of the present invention group The disintegrant and lubricant of conjunction are also fine with effect in tablets, can quickly make drug-eluting;In addition, manufacture craft is simple, Cost is saved, is suitble to large-scale industrial production.
