The faropenem pharmaceutical composition that contains glutathion
Technical field
The present invention relates to a kind of stable Pharmaceutical composition, be particularly related to and contain faropenem or its pharmaceutically acceptable salt or medicinal compound of hydrate, said composition contains pharmaceutically acceptable salt of glutathion or its, and wherein both weight ratio scopes are 25: 1~1: 1.
Background technology:
Early 1940s, penicillin is applied to clinical, has drawn back antibiotic curtain.Penicillin antibiotics and cephalosporin are two maximum class antibiotic of clinical practice, but along with clinically extensive application and abuse, drug resistance constantly increases, and its range of application is restricted.Penem is the novel beta-lactam compound of a class, and is stable to dehydropeptidase of kidney, do not need and the beta-lactamase inhibitor drug combination.
Faropenem sodium is a kind of synthetic blue or green enzyme alkene class broad ectrum antibiotic, and antibacterial action is strong, but its instability is easy to hydrolysis, oxidation, photoisomerization etc.Faropenem demonstrates broad-spectrum antibacterial activity to aerobic and anaerobic gram positive bacteria, gram-negative bacteria, and particularly the activity to anaerobe such as gram positive bacterias such as drug-fast staphylococcus, enterococcus and bacteroids all is better than existing Perorally administrable antimicrobial agent; But to the activity of bacillus pyocyaneus a little less than.All very stable to various beta-lactamases, less generation drug resistance.
The faropenem oral absorption is effective, and the half-life is about 1 hour in the blood.Day dosage is 450~900mg (divides 3 times oral).General clinical research result shows that the effective percentage of treatment respiratory infections is 78.6%; The urinary tract infection effective percentage is 73.4%; The skin infection effective percentage is 88.6%; The surgical infection effective percentage is 89.0%; It is 87.5% that department of obstetrics and gynecology infect effective percentage; It is 74.1% that ear nose section infects effective percentage; It is 87.3% that ophthalmology infects effective percentage; It is 86.8% that the dentistry and the department of stomatology infect effective percentage.Clinical isolated bacterial clearance rate is respectively: golden Portugal bacterium is 79.2%; Bacterium is 92.0% in blue or green Portugal; Streptococcus pneumoniae is 78.3%; Enterococcus faecalis is 91.8%; Escherichia coli are 91.3%; Pneumobacillus is 81.5%; Hemophilus influenza is 66.7%.Adverse reaction rate is 4.9%, is slight gastrointestinal symptom and allergy symptoms.
Faropenem is the penems antibiotics of Japanese Suntory company exploitation, obtains the chemical compound patent in 1986 in Japan, and the patent No. is JP61,207387.Nineteen ninety and 1992 Japanese Yamanouchi drugmaker and U.S. Wyeth-Ayerst company obtain the clinical licence of these product respectively, carry out its clinical research jointly.And with at first got permission listing in 1997 in Japan, commodity are called Farom.
Faropenem belongs to first and is used for clinical penem antibiotic, both can be oral, again can administrated by injection, and be applicable to the patient of different gradient of infection.Its curative effect and safety have obtained fully certainly.
But the faropenem preparation causes the preparation instability owing to the reason of multiple reason, particularly chemical constitution, easy decomposition and degeneration, the content of the preparation of producing related substance (impurity) after placing 6 months is elevated to 5% at present, causes the product active constituent content to reduce, and affects the treatment.
The present invention adds glutathion through research in the preparation of faropenem, improved the stability of faropenem greatly, has prolonged effect duration.
Summary of the invention:
In order to overcome the deficiencies in the prior art part, researcher of the present invention finds that having added glutathion in the faropenem preparation of sodium increases the Faropenem sodium stability of formulation greatly.
The object of the present invention is to provide a kind of stable Pharmaceutical composition, it is characterized in that containing faropenem and glutathion.
Another object of the present invention is to provide the dosage form of the compositions that contains faropenem and glutathion, finally reach the purpose of stable pharmaceutical composition of the present invention.
The invention provides a kind of faropenem of physiology effective dose or Pharmaceutical composition of its pharmaceutically acceptable salt or its hydrate of containing, contain pharmaceutically acceptable salt of glutathion or its in the said composition.
Compositions of the present invention, wherein faropenem or its pharmaceutically acceptable salt or hydrate and glutathion weight ratio scope are 25: 1~1: 1.Preferably 25: 1~6: 1.
Compositions of the present invention, wherein said faropenem or its pharmaceutically acceptable salt or hydrate are Faropenem sodium 2.5 hydrates, and glutathion is a reduced glutathion.
Compositions of the present invention, be unit dosage form, these unit dosage forms can be pharmaceutical preparation unit dosage forms commonly used, as: the tablet of unit dose, capsule, granule or injection powder pin, for tablet, capsule or injection powder pin, unit dose refers to every, every capsules, every injection, for granule, unit dose is meant every bag granule, every bottle of granule, or every gram granule.
Compositions of the present invention, if tablet or capsule wherein in each tablet or the capsule, contain Faropenem sodium 2.5 hydrate 123.5mg, reduced glutathion 20mg, other are the medicine acceptable carrier.If granule contains Faropenem sodium 2.5 hydrate 123.5mg in every gram granule, reduced glutathion 10mg, other are the medicine acceptable carrier.If powder ampoule agent for injection in every powder ampoule agent for injection, contains Faropenem sodium 2.5 hydrate 125mg, reduced glutathion 5mg.
The present invention also provides the preparation method of the present composition, and this method comprises faropenem or its pharmaceutically acceptable salt or its hydrate and glutathion or its blended step of acceptable salt pharmaceutically.
Preparation of the present invention according to the needs of preparation, can add galenic pharmacy medicine acceptable carrier commonly used.Can be prepared into finished product preparation according to the conventional method of galenic pharmacy, and be applied to suitability for industrialized production.
